Task 1 – National Survey Report of PV Power Applications in Sweden
What is IEA PVPS TCP?
The International Energy Agency (IEA), founded in 1974, is an autonomous body within the framework of the Organization for
Economic Cooperation and Development (OECD). The Technology Collaboration Programme (TCP) was created with a belief that
the future of energy security and sustainability starts with global collaboration. The programme is made up of 6 000 experts across
government, academia, and industry dedicated to advancing common research and the application of specific energy technologies.
The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCP’s within the IEA and was established in 1993. The
mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy
as a cornerstone in the transition to sustainable energy systems.” In order to achieve this, the Programme’s participants have
undertaken a variety of joint research projects in PV power systems applications. The overall programme is headed by an Executive
Committee, comprised of one delegate from each country or organisation member, which designates distinct ‘Tasks,’ that may be
research projects or activity areas.
The IEA PVPS participating countries are Australia, Austria, Belgium, Canada, Chile, China, Denmark, Finland, France, Germany,
Israel, Italy, Japan, Korea, Malaysia, Mexico, Morocco, the Netherlands, Norway, Portugal, South Africa, Spain, Sweden, Switzerland,
Thailand, Turkey, and the United States of America. The European Commission, Solar Power Europe, the Smart Electric Power
Alliance (SEPA), the Solar Energy Industries Association and the Cop- per Alliance are also members.

What is IEA PVPS Task 1?
The objective of Task 1 of the IEA Photovoltaic Power Systems Programme is to promote and facilitate the exchange and
dissemination of information on the technical, economic, environmental and social aspects of PV power systems. Task 1 activities
support the broader PVPS objectives: to contribute to cost reduction of PV power applications; to increase awareness of the potential
and value of PV power systems; to foster the removal of both technical and non-technical barriers and to enhance technology co-
operation. An important deliverable of Task 1 is the annual “Trends in photovoltaic applications” report. In parallel, National Survey
Reports are produced annually by each Task 1 participant. This document is the country National Survey Report for the year 2019.
Information from this document will be used as input to the annual Trends in photovoltaic applications report.

1 INSTALLATION DATA
The photovoltaic (PV) power systems market is defined as the market of all nationally installed (terrestrial) PV
applications with a PV capacity of 40 W or more. A PV system consists of modules, inverters, batteries and all
installation and control components for modules, inverters and batteries. Other applications such as small mobile
devices are not considered in this report.
For the purposes of this report, PV installations are included in the 2019 statistics if the PV modules were installed
and connected to the grid between January 1st and December 31st of 2019, although commissioning may have
taken place at a later date.
Applications for Photovoltaics
The installation of grid connected PV systems in Sweden can be said to have taken off in 2006, when about 300
kW was installed that year. Before that only a few grid-connected systems were installed each year. Until 2006, the
Swedish PV market almost exclusively consisted of a small but stable off-grid market where the majority constituted
of systems for holiday cottages, marine applications and caravans. This domestic off-grid market has been quite
stable throughout the years. But since 2007 more grid-connected capacity than off-grid capacity has been installed
annually. The grid-connected market is almost exclusively made up by distributed roof-mounted systems installed
by individual homeowners, companies, municipalities, farmers, etc. Already from the start, the Swedish distributed
market has been driven by the self-consumption business model, as there has never existed a feed-in-tariff in
Sweden. Capital subsidies in combination with different types of schemes that add value for the excess electricity
has until now been crucial for this business model to work in Sweden. About 46 % of the installed grid-connected
PV power are residential systems and 46 % are installed on commercial facilities.
With regards to Building-Integrated PV (BIPV) in the decentralized market segment, several companies offer
different solutions and the feeling (without any backing of statistics) is that the number of BIPV projects in Sweden
is increasing.
So far only a couple of relatively small ground-mounted centralized PV parks, 5 % of the grid-connected market,
have been built. But the interest and activity in this market segment has increased a lot in 2019 and the number
and sizes of centralized PV parks are expected to increase in the coming years.
Annual installed PV capacity
The installation rate of PV continues to increase at a high speed in Sweden. A total of 288.93 MW was installed in
2019, as shown in Figure 1 and Table 2. This means that the annual Swedish PV market grew with 59 % compared
to the 182.19 MW that was installed in 2018.
In recent years, the market for grid-connected PV systems has grown rapidly in Sweden. This continued in 2019 as
another 286.99 MW of grid-connected systems were installed under the year, a 59 % increase compared to the
180.15 MW installed in 2018.
Of the grid-connected PV capacity installed in 2019, 11.45 MW is estimated to be centralized PV parks and 275.55
MW distributed PV systems for primary self-consumption. By that, the annual market of centralized PV in Sweden
grew with about 22 % and the distributed annual market by 61 % as compared with 2018, when approximately 9.40
MW of centralized and 170.75 MW of distributed PV was installed.
Sweden has a stable off-grid PV market. In 2017 and 2018, about 2.06 MW and 2.03 MW respectively of off-grid
applications were sold. In 2019 the off-grid market decreased slightly to 1.94 MW.

The numbers for total installed PV capacity by the end of 2019 listed in this report are based on two data sources.
All the grid-connected PV capacity is collected through surveys sent out by Statistics Sweden, SCB, (Statistiska
Centralbyrån) on behalf of the Swedish Energy Agency (Energimyndigheten) to all the Swedish grid operators [1].
As it is mandatory to notify the grid operator when a PV system is connected to the grid, the grid operators should
have all the grid-connected PV systems within their grid area registered, and they are obliged to share this
information with the Swedish Energy Agency. The accuracy of the grid connected capacity is therefore judged to
be high.
The official collection of grid-connected PV capacity by the surveys to the grid operators has only been carried
out for the years of 2016, and thereafter. The historic numbers for the installed grid-connected PV capacity (and
off-grid PV capacity) in Sweden until the end of 2015 are therefore exclusively based on the yearly collection of
the sales statistics by the Swedish representatives in IEA PVPS task 1. For 2016 and 2017 weighted average
number between the sales statistics and the statistics from the grid operators has been used due to uncertainties
about the quality of the grid operators’ statistics these years. For a more detailed description see the 2018 version
of National Survey Report of PV Application in Sweden [2].
Data for off-grid PV systems are by definition impossible to get from the grid operators. The information about
installed off-grid PV capacity is therefore based on cumulative sales statistics that have been collected directly
from company representatives throughout the years by the Swedish representatives in IEA PVPS task 1. Off-grid
systems older than 20 years are assumed to have been decommissioned by now and are therefore withdrawn
from the cumulative sales statistics to obtain the total off-grid capacity in Sweden. The companies that have
contributed off-grid data for 2019 are listed in section 4.6. Older Swedish National Survey Reports list the active
companies for the sales statistics for their respective year. The accuracy of the off-grid capacity is judged to be
much lower than for the grid connected capacity.

Total installed PV capacity
The total grid-connected capacity at the end of 2019 was 698.05 MW, according to the grid operators. Out of this
capacity about 30.52 MW is estimated to be centralized PV and 667.53 MW to be distributed. In addition, a total of
18.27 MW of off-grid PV applications have been sold in Sweden since 1993, wherein 15.82 MW is estimated to still
be in operation.
By adding the off-grid and the grid-connected PV capacities together, one can conclude a total of 713.87 MW of
electricity producing PV power by the end of 2019, illustrated in Figure 2 and summarized in Table 4. The total
installed PV capacity grew by 68 % in 2019, which is in line with the marked development over the five previous
years, where the total market grew by 59 % (2018), 46 % (2017), 47 % (2016), 63 % (2015) and 85 % (2014).
The strong overall growth in recent years started with the introduction of the direct capital subsidy system (see
section 3.2.1) in 2006, and has since then been fuelled by the declining system prices (see section 2.2), high
popularity among the public (see section 1.6.2), a growing interest from utilities (see 7.2) and an ongoing reformation
work from the Government to simplify the rules for micro-producers (see section 3.3).
In total there were 43 944 grid-connected PV systems in Sweden by the end of 2019. The number of off-grid systems
is unknown. A majority of the grid-connected PV systems, 37 656, are small systems below 20 kW. 6 277 are in
between 20 kW – 1000 kW and only eleven systems are above 1 MW according to the official statistics (summarized
in Table 5). However, the official statistics count everything behind one single connection point to the grid as one
system. Several of the centralized PV parks built in Sweden have several connection points to the low voltage
distribution grid. These PV parks are divided into several systems in the statistics, and often in sizes below 1 MW.
So, the actual number of PV systems above 1 MW in Sweden is larger than eleven the way most people would see
it.
With regards to the number of installed PV systems in Sweden, statistics are available for grid-connected system
for the years 2016 to 2019. The number of systems at the end of each year, and the corresponding average system
size is presented in Table 6. As can be seen at the end of 2019, Sweden had 43 994 grid-connected PV system,
and the corresponding average system size was about 16 kW. That is a relatively small system size and it clearly
illustrates that the Swedish PV market mainly consist of small distributed PV systems.

PV market segments
The official statistics of the grid operators, collected by the Swedish Energy Agency, only include segmentation in
PV system sizes (power) in the ranges 0–20 kW, 20–1000 kW and >1000 kW. The total installations at the end of
2019, according to this source, are summarized in Table 7.

However, for market segmentation there is another data source. In the database of the Swedish direct capital
subsidy (see section 3.2.1), called Svanen, all PV systems that have been granted support from the start of the
subsidy programme in 2009 until now are recorded. By cross-referencing between this database and Sweden’s
national business directory, a business sector can be assigned to each system owner. By doing this, the database
can be divided into centralized, industry, commercial or residential systems. It is also possible to sort the PV systems
based on if they were installed on “ground (mark)”, “single-family houses/small buildings (småhus)”, “multi-family
houses (flerbostadshus)”, “facilities (lokaler)” or “other (annat)”. The Swedish standard classification names for the
different type of buildings are added within the parenthesis to make it easier for the Swedish readers as there in
some cases are no straightforward translations into English for these building types. The “other (annat)”
classification includes all installations that do not fit into the other building types. This could be decentralised ground
mounted systems, systems on churches or other cultural buildings and systems on schools just to mention a few.
A problem with the Svanen database is however that a lot of systems have been recorded in an incorrect way, for
example with the wrong power rating, granted subsidy or organization. When it is obvious that the information has
been recorded incorrectly, these systems have manually been removed for the analysis within this report.
The installed PV capacity in the Svanen database for 2019 is lower than the total installed as recorded by the
Swedish Energy Agency. However, by dividing the annual installed PV capacity in Svanen for each market segment
by the total installed PV capacity in Svanen, the different market segments share of the annual installations can be
estimated. The historic development of these shares is presented is presented in Figure 3.
As Figure 3 clearly illustrates, the biggest market segments in Sweden have been residential single-family houses
and commercial facilities. A slight variation over the years can be seen in Figure 3, but these two segments have
always been the biggest. The reason for that is that the self-consumption business model is easy to implement for
these types of buildings.

Task 1 – National Survey Report of PV Power Applications in Sweden
11
The low shares of the other market segments, such as centralized PV parks, industry and residential multi-family
houses can all be explained by the current policy structure in Sweden.
The reason for the underdeveloped Swedish market of centralized PV parks, as compared to in many other
countries, is that the current support schemes has not been enough do drive PV park development in Sweden until
now. The two support schemes that has been available has been the renewable electricity certificate system
(see section 3.2.3) and a maximum 1.2 million SEK per system from the direct capital subsidy programme (see
section 3.2.1). However, this is a market sector that is expected to grow in the coming years. At the time of writing
there are thirteen commenced PV parks in Sweden that are larger than 1 MW. Besides those mentioned, the authors
are aware of additional plans for several larger PV parks. It seems as though this sector is on the brink of managing
without any subsidies, with the help of innovative business models such as PPA-contracts and PV cooperative
models (see section 2.4).
The almost absent market segment of PV systems on industry properties can be explained by the current tax laws.
First, the manufacturing industry in Sweden has a reduced energy tax. Instead of paying the full energy tax of 0.347
SEK/kWh they only pay 0.005 SEK/kWh. Therefore, the value of self-produced and consumed electricity becomes
lower for manufacturing industries as compared with actors that pay the full energy tax. The other major policy
obstacle for this market segment is the 255-kW limit (see section 3.3.2), where an owner of a system larger than
255 kWp pay energy tax on the self-produced and consumed electricity as well. Many larger industries consider PV
systems of <255 kWp too small to consider, and therefore do not invest in PV, even if they have excellent roofs and
high electricity consumption.
The general obstacle for residential multi-family houses is the current tax laws which makes it complicated to self-
consume PV electricity in the apartments of a multi-family house. The most common situation is that the apartments
have their own meter and contract with the grid operators and the whole multi-family house has one separate meter
and contract for the electricity consumed in common areas of the house, e.g. elevators, laundry room, lighting. With
this arrangement it is only possible to use the produced PV electricity (from a PV system on the building) for the
electricity consumption of the common areas. If the owner of the multi-family house wants to sell the PV electricity
to the apartments, the owner becomes a retailer of the electricity and must follow the regulations which come along
with that role including the Swedish energy tax that is applied to the electricity (even if it has not left the building).
Hence, it is difficult to reach a high degree of self-consumption in multi-family houses arranged this way. The value
Figure 3: Various market segments share of the annual installed PV capacity in Sweden in 2019. Based on
statistics from the capital subsidy database Svanen. The written percentages in the graph represents the
total shares of Residential, Commercial, Industry and Centralized.

of the excess electricity exported to the grid drops if the fuse exceeds 100 amperes (see section 3.3.5), thus it
becomes hard to achieve a decent profitability for such installations. However, it is possible to self-consume the PV
electricity in the apartments without taxes if the whole multi-family building, including the apartments, share one
single meter and contract with the grid operator. This arrangement requires that the electricity consumption in the
apartments is included in the general rent of the apartments. And then it is up to the owner of the multi-family house
to decide if the residents in the apartments should pay a fixed price for the electricity regardless of their consumption,
or handle the metering of the electricity consumption themselves and vary the level of the monthly rent for the
residents depending on their electricity consumption. The latter solution becomes more and more common in
Sweden, but the general complexity to move to this arrangement is one reason for the low installation numbers for
multi-family houses. Several proactive housing and property companies have however experienced added values
after investments in PV, such as sustainability, fair cost, and induced innovativeness [3]. These experiences are
likely to spread over time to other actors and motivate them to overcome the perceived legislative barriers.
The geographical distribution of PV in Sweden
The data from the grid operators’ statistics about the installed PV power in Sweden has a geographical resolution
down to municipality-level. This data has been used to illustrate the geographical distribution of PV in Sweden in
Figure 4 and Figure 5 for most of the municipalities in Sweden. However, some municipalities are marked as blank
by the public Swedish Energy Agency due to confidentiality reasons. For these municipalities, data from the green
electricity certificate system (see section 3.2.3) has been used to complement the grid operators’ data in creating
Figure 4 and Figure 5.
In 2016 these municipalities were Ale, Arjeplog, Arvidsjaur, Bjurholm, Dorotea, Fagersta, Gällivare, Habo,
Haparanda, Hedemora, Hofors, Jokkmokk, Kalix, Kiruna, Ljusnarsberg, Ludvika, Lycksele, Lysekil, Malå, Munkedal,
Munkfors, Nordmaling, Pajala, Sala, Sorsele, Storuman, Sundbyberg, Sävsjö, Tanum, Tidaholm, Täby, Umeå,
Vilhelmina, Vännäs, Åsele, Älvsbyn, Örebro and Överkalix.
In 2019 these municipalities were Ale, Arjeplog, Arvidsjaur, Borgholm, Haparanda, Hultsfred, Norberg, Skellefteå,
Sorsele, Storuman, Surahammar, Åmål, Överkalix.
Figure 4 and Figure 5 clearly show that the expansion of PV takes place at different speeds in Sweden's
municipalities. When it comes to most installed PV capacity, Gothenburg, followed by Uppsala and Stockholm were
in the top at the end of 2019 with 22.6, 18.9 and 17.0 MW, respectively. Gothenburg, who overtook the lead from
Linköping in 2018, was much helped by the 5 MW PV park that was finalised on Hisingen in December 2018. The
local utility company is building another 5 MW PV park in 2020.
When the installed PV capacity is divided by capita, as in Figure 5, Sjöbo municipality overtook the last year’s leader
Heby in 2019. The main reason for that is that Sweden’s so far biggest PV park, “Sparbanken Solcellspark” at 5.8
MWp was commissioned in Sjöbo last summer. Sjöbo only has about 19 200 inhabitants, so the PV park had a huge
effect. The top three municipalities then became Sjöbo, Heby and Simrishamn with 405.2, 242.8 and 230.5
W/capita, respectively. It is no coincidence that Heby and Simrishamn also are in the forefront. In Heby, Swedens
first PV cooperative was started already in 2009 (see section 2.4) and in 2018 Swedens largest roof-mounted PV
system was installed on a logistics center. In Simrishamn the utility E.On is running a smart grid project in the village
Simiris where they will run the whole village on solely locally produced wind and PV electricity in an island mode
every fifth week.
The Swedish electricity market is from the first of November 2011 divided into four bidding areas by decision of the
Swedish National Grid (Svenska Kraftnät), marked as SE1, SE2, SE3 and SE4 in Figure 4 and Figure 5. The reason
is that northern Sweden has an excess of electricity production, since that is where a lot of the wind power and a
majority of the hydropower is situated, while the demand is larger than the production in southern Sweden. This
has resulted in transmission bottlenecks, and the borders between the bidding areas have been drawn where there
are congestions in the national grid. The idea of the four bidding areas is to make it clear where the national grid
needs to be expanded and where an increased electricity production is required to better meet the consumption.

Task 1 – National Survey Report of PV Power Applications in Sweden
13
From this perspective, it is positive that a majority of the PV capacity is being installed in southern Sweden and
mainly in the densely populated municipalities, as Figure 4 shows.
The value of the PV electricity is also higher in SE4 and SE3, as the average value factor between 2014 and 2019
(see section 2.6 for further explanation and discussion) of PV in these bidding areas was 1.028 and 1.025
respectively, as compared to 1.024 in both SE2 and SE1 respectively [4].

Key enablers of PV development
1.6.1 Other technologies
For four years the surveys that went out to the installation companies included questions about grid connected
battery capacity that had been installed. According to the installations companies a total battery capacity of 6 362
kWh was installed in 2019,, a slight increase compared to 2018 Table 8: Annual installed grid connected stationary
battery capacity installed by PV installation companies. illustrates. The general global trend of decreasing battery
prices [5], signals that a growing battery market in Sweden is expected. In 2018 a clear shift can be seen Table 8:
Annual installed grid connected stationary battery capacity installed by PV installation companies., as compared
to previous years, where the battery market for private households became larger than the market for commercial
systems. This development can be explained by the introduction of the capital subsidy programme for storage (see
section 3.9.3), which now has an effect on the storage market.
The reader should be aware that this battery capacity is not the total annual installed grid connected battery capacity
in Sweden. It is only the battery capacity that PV installation companies have installed in connection to distributed
PV systems.

1.6.2 The public opinion about PV
The general opinion about PV in Sweden is very positive among the public. In an annual survey [8], sent out by the
SOM-institute, randomly selected respondents have answered the question “How much should Sweden invest in
the following energy sources during the next 5-10 years?”. The result is presented in Figure 6, indicating a strong
majority of 82 % of the respondents want more investments in PV in Sweden, which makes the PV technology by
far the most popular electricity production technology in that aspect.
When it comes to the willingness of homeowners to install PV on their house, the results from two different surveys
conducted with national representative samples of Swedes, are presented in Figure 7. The survey presented in
Figure 7a is from 2016 [9] and the one presented in Figure 7b from 2018 [10]. The results from the two surveys are
similar and show that about 60 % of the homeowners in Sweden are interested in having a PV system on their roof.
Finally, there is also a great interest for larger PV systems, and scientific analysis has shown that the installation of
PV systems creates a number of added values for commercial and multi-family building owners [3].
Figure 6: The public opinion in Sweden about different electricity production technologies.
Figure 7: The result of two different surveys conducted with a national representative sample of Swedes.
In (A) the question was “If you had the opportunity, would you then like to produce your own electricity?”
In (B) the question was “As a homeowner, have you installed PV or are you planning to do so?”.

PV in the broader Swedish power system
The complete statistics of the Swedish electricity production of 2019 is not yet available. In Figure 9 the Swedish
electricity production in 2018 is presented. The electricity production data used in Figure 9 and Figure 8, along with
Table 10, were retrieved from Svenska Kraftnät [11] but with complementary data from SCB [12] with regards to
the fuels used in the Swedish CHP power plants. The exception is the produced PV power. Since a large share of
the total PV power production is self-consumed by prosumers it is not registered in the statistics from Svenska
Kraftnät as they only measure electricity fed into the grid. The PV production used in the figures and table below
were therefore instead generated through simulations using a model that have a proven high correlation of 0.95–
0.99 to reported historical production data [13].
The simulation result was generated in proportion to the geographical location of the population and the available
solar radiation, this was done in order to ensure that the solar production was distributed realistically. For each year
the production was calculated from the average installed power at the beginning and the end of the year and was
weighted against values on the installed capacity.
Figure 9: Total electricity production in Sweden in 2018.

As can be seen in Figure 8, the Swedish electricity has historically been produced by technologies that have a low
CO2-footprint. This along with the low electricity prices (see section 2.6) counts as the two main reasons why the
Swedish PV deployment started late compared to other European markets and still is rather small.

2 COMPETITIVENESS OF PV ELECTRICITY
Module prices
Module prices in Sweden are heavily dependent on the international module market. Sweden saw a very rapid
decline in price for PV modules between 2008 and 2013 due to a growing domestic market, which allowed retailers
to import larger quantities. But also due to the overall price decline of modules on the international market. Between
2013 and 2016, the price decline in Sweden was more moderate.
One of the reasons for the stabilization of module prices in this time period was the import duties on Chinese PV
modules and cells that were introduced in 2013 by the European Commission [14]. In these measures, a minimum
import price (MIP) was introduced, which means that no silicon solar cells or modules could be imported to the
European Union at a price lower than 0.56 €/Wp, which corresponded to about 5.2 SEK/Wp.
In September 2018 the European Commission terminated the duties on Chinese modules. After the termination of
the duties many Swedish retailers lowered their module prices towards the Swedish installation companies with 20-
30 percent. That resulted with the price of a typical module to the end consumer going down by 15 % in 2018, which
continued in 2019 with an additional average price drop of 9 % (see Table 11), according to sales statistics.
Table 11: Typical module prices for a number of years. The prices are reported by Swedish installers and
retailers. The prices are the prices to the end costumer, not the import price for the installers and retailers.

System prices
Sweden has experienced a large decrease in PV system prices since 2010, especially before 2013, as Figure 10
shows. The major reason for the decline in system prices in Sweden is that the prices of modules and the balance
of system (BoS) equipment has dropped in the international market. Another reason is that the Swedish market is
growing, providing the installation firms a steadier flow of orders and an opportunity to streamline the installation
process, thus reducing both labour and cost margins. A clear trend of decreasing yearly full-time labour positions
per installed MW is illustrated in Table 33 further corroborate this hypothesis. Competition in the market has also
increased. In 2010 the author of this report was aware of 37 active companies that sold and/or installed modules or
PV systems in Sweden. In the end of 2019, the corresponding figure had gone up to 314.
2.2.1 Estimated PV system prices by the sales statistics
When it comes to PV system prices, there are two different data sources. One is the sales survey that yearly goes
out to the Swedish installers and retailers as part of the collection of data for this and previous Swedish National
Survey Reports. These surveys have been conducted the same way since 2010, and they collect statistics about
prices that the installer and retailer companies regard as typical for some standard PV systems for their company.
The reported prices have for the years 2010–2017 been weighted with regards to the number of kWp each company
installed in that market segment. For the 2018 and 2019 numbers, the reported prices have not been weighted (as
the collection of installation data from the installation companies after 2017) and the reported prices are a regular
average. The price information from the sales surveys are presented in Figure 10 and Table 11.

2.2.2 PV system prices recorded in the direct capital subsidy programme
The other source for system price statistics is the database of the Swedish direct capital subsidy, called Svanen.
As described more in detail in section 1.4 it is possible to sort the PV systems by market segment, meaning if they
have been installed on “ground (mark)”, “single-family houses/small buildings (småhus)”, “multi-family houses
(flerbostadshus)”, “facilities (lokaler)” or “other (annat)”. The Swedish standard classification names for the different
type of buildings are added within the parenthesis to make it easier for the Swedish readers as there is some cases
are no straightforward translations into English for these building types. So, most PV systems in the database can
be divided into centralized, industry, commercial and residential systems, and as the system sizes (in kWp), prices
and commission dates are also recorded, it is possible to extract price information within the different market and
size segments, as well as follow the price development over the years.
When it comes to the prices of turn-key grid connected roof-mounted PV systems there is of course a wide range,
even for systems with similar size and type of owner. The range depends on many factors, such as type of building,
type of roof, type of module and BoS, etcetera. Furthermore, it is not possible to derive if the PV systems are
building applied (BAPV) or building integrated (BIPV), or if the owner has carried out some of the installation work
by him/herself. These factors result in several recorded PV system prices (especially in the segment of small
residential single-family systems) that are unusually high >30 SEK/Wp or low <10 SEK/Wp.
Furthermore, there is also the economies of scale, where larger systems are comparatively cheaper to install due
to the fact that some costs, such as for example designing of the system, erection of scaffolding, commissioning
etc, depends little on the number of modules that are being installed.

Task 1 – National Survey Report of PV Power Applications in Sweden
21
For this report several size (power) ranges for residential and commercial systems have been selected and an
average has been derived within these size ranges for PV systems. The reason for choosing these size intervals is
because the number of systems should suffice to derive a reasonable average price and that the economies of
scale become less profound the larger the system becomes. For the residential sector the size ranges are 5–10
kWp and 10–20 kWp for single-family houses, and 20–50 kWp and 50–100 kWp for multi-family houses. The average
prices for residential systems are presented in Figure 11 and Table 13. For the commercial sector the size ranges
are 10–20 kWp, 20–50 kWp, 50–100 kWp and 100–255 kWp, presented in Figure 12 and Table 14. The reason for
choosing 255 kWp as the upper boundary for the largest commercial systems is due to the current tax legislation
(see section 3.3.2). Table 13 and Table 14 also list how many systems that the presented average prices have
been derived from, in order for the reader to get a sense of relevance of the average price presented.
The reason for only presenting prices from 2013 and onwards, and not to include 2009–2012 even if they exist in
the database, is that the number of systems installed those years is so small and the spread of prices between
them so high that deriving an average price of these systems would be precarious and misleading.

2.2.3 PV system price discussion
The fast decrease in PV system prices in Sweden the last few years has slowed down, but a declining price trend
can still be seen. For small PV systems on residential single-family houses of approximately 5 to 10 kWp, both

Task 1 – National Survey Report of PV Power Applications in Sweden
24
Table 12 (that is based on the installations companies estimates) and Table 13 (that is based on prices statistics
derived from the Swedish direct capital subsidy programme) show that the price decreased in 2019, with around
3–4 % to reach an average of 14.2 SEK/Wp. The price of somewhat larger PV systems on residential single-family
houses of about 10–20 kWp also declined with about 4 %, as the average prices in this market segment went down
from 12.7 to 12.1 SEK/Wp (see Table 13Table 13). For residential PV systems on multi-family houses the prices
went down with 1 % and 5 % within the size ranges of 20–50 kWp and 50–100 kWp respectively in 2019.
For roof-mounted PV systems on commercial buildings the price decline seems to have followed the same pace as
the prices went down with 2 % for ~100 kWp systems and 3 % for ~15 kWp systems according to installation
companies (see Table 12). However, Table 14 show that prices for commercial facilities were about the same in
2019 as in 2018.
It is interesting to note that for small residential single-family houses the installation companies estimate typical
system prices at the same level as what have actually been recorded in the direct capital subsidy programme,
namely on average 14.2 SEK/Wp, while for large commercial systems of about 100 kWp the installation companies
estimate lower typical system prices (10.1 SEK/Wp) as compared to the average of the recorded systems in the
direct capital subsidy programme (11.6 SEK/Wp). Looking in the database of the direct capital subsidy programme
a few outlier systems with system prices >30 SEK//Wp are noted in this category, which pull up the average prices.
Consequently, it seems like the typical price for a large commercial PV system of about ~100 kWp was closer to 10
SEK/Wp in 2019.
The largest price decline in 2019 occurred for centralized utility scale PV parks, where the typical price went down
with 8 % from 8.2 SEK/Wp to 7.5 SEK/Wp (see Table 12). An explanation is that five >1 MWp PV parks were
commissioned in Sweden in 2019.
The general slowdown of the price reduction of PV system is expected as it is impossible to continue with such a
fast price reduction as was seen a couple of years ago when the Swedish market was catching up the international
market prices. The stagnation of the prices for the residential and small commercial sector might be explained by
the very high demand for PV in Sweden. The fact that the subsidy levels in the Swedish direct capital subsidy
system haven’t been lowered since 2014 until it was changed in May 2019, may be another reason (see section
3.2.1). This means that the installers could charge the same prices, as the customers have the same profitability,
even if module and other hardware costs has continued to go down.
Table 15 summarizes the PV system prices in 2019. The price ranges presented are appraisals made by the authors
and are based on data from both the installer and retailers’ surveys and the Svanen-database of the direct capital
subsidy.

Financial parameters and specific financing programs
The interest rate (reporäntan) of the central bank of Sweden (Riksbanken) started at -0.5 % in 2019, but was
increased to -0.25 % on the 9th of January and was then kept at that level for the entire year [15]. Changes in interest
rate by the central bank have a direct impact on the market rates, which therefore have been quite low in 2019. The
cost of capital for a PV system has consequently been low.
In Table 16 the average mortgage rate in 2019 has been used for residential installations. For commercial
installations in Sweden a realistic loan rate has been reported to be the STIBOR rate plus 450 dps. A study to derive
the levelized cost of electricity (LCOE) of Swedish centralized PV parks projects under 2019 and 2020 are taking
place right now, and preliminary average weighted average cost of capital (WACC) from this study is used for
industrial and ground-mounted installations in Table 16.

To the knowledge of the authors, the first loan specifically directed to PV installations in Sweden was launched in
2019. It is Sparbanken Syd that now offer private persons to finance their investment in PV systems on their house
by a specific PV loan [18].
Specific investments programs
Already in 2009, the first PV cooperative, Solel i Sala & Heby ekonomisk förening, started in Sweden. This PV
cooperative has a FiT agreement with the local utility company Sala-Heby Energi, that buys the electricity from the
cooperatives PV systems. Since the start in 2009 the cooperative has now built six systems with a total capacity of
599 kWp. Other examples of PV cooperatives that has built co-owned PV systems are Solel i Bergslagen ekonomisk
förening, with two systems totalling 112 kWp, and Zolcell 1:1 ekonomisk förening, with 2 systems totalling 27 kWp.

PV cooperative models have in later years been adapted by utility companies that have built large PV parks or
systems. Any private person or company can buy a share in such a park and the shares represent a certain yearly
production, which the utility company deduct from the share owner’s electricity bill. One examples of this is the 1
MWp park with solar tracking outside of Västerås, which the utility company Mälarenergi and the installation
company Kraftpojkarna manage together. Another example is Kalmar Energi that installed a crowdfunded 600 kWp
system on the roof of a local farm called Nöbble Gård. Following the positive response of Nöbble Gård Kalmar
Energi is now building big crowd funded PV park close to the Kalmar Airport. This park will be built in four stages of
750 kWp each. The first one was finalized in the end of September 2017, the second in June 2018 and the third in
May 2019. The first stage, 0.6 MW, of their crowd funded PV park was finalized in April 2019, the second stage of
another 0.6 MW was in June 2019 and at the time of writing 60 % of a third stage has been financed.
In 2014 there was no company offering PV leasing contracts. However, in 2015, the company Eneo Solutions AB
started to offer solar leasing contracts to owners of commercial and public buildings. In 2016 two utility companies,
Umeå Energi and ETC El started to offer solar leasing contracts to private homeowners.
Additional Country information
Sweden is a country in northern Europe. With a land area of 407 284 km² [19], Sweden is the fifth largest country
in Europe. In January 2017 Sweden passed ten million inhabitants for the first time in history [20]. The population
density of Sweden is therefore low with about 25 inhabitants per km², but with a much higher density in the southern
part of the country. About 85 % of the population lives in urban areas.

Electricity prices
In Sweden, the physical electricity trading takes place on the Nordic electricity retailing market, Nord Pool Spot
market. Historically, electricity prices in Sweden have primarily been dependent on the rainfall and snow melting,
the availability of the nuclear reactors and the outside temperature. In recent years, a lot of wind power has been
built and more transmission connections to surrounding countries have come online, which affect the spot prices
on windy days.
The Swedish electricity market is from the first of November 2011 divided into four bidding areas by decision of the
Swedish National Grid (Svenska Kraftnät). The reason is that northern Sweden has a surplus of electricity
production compared to the demand, while there is a higher demand than production in southern Sweden. That has
resulted in transmission capacity problems and the borders between the bidding areas have been drawn where
there are congestions in the national grid. The idea of the four bidding areas is to make it clear where in Sweden
the national grid needs to be expanded and where in the country increased electricity production is required to
better meet consumption, and thus reduce the need to transport electricity long distances. The geographical borders
of the areas are marked in Figure 4 and Figure 5.

In 2019 the spot prices were quite stable over the year, as Figure 13 illustrates, and the yearly average ended up
at 0.401 in SE1, 0.401 in SE2, 0.405 in SE3 and 0.421 in SE4. The very small difference between the areas does
not influence the distribution of PV systems over the country to the same extent as solar radiation (see section 2.7)
and the population distribution does (see section 1.4). Looking back over the last six years, the spot prices have
varied quite substantially in Sweden, as Figure 14 and Table 19 illustrates, which makes it harder to predict the
business case of centralized PV parks. With more in-depth analysis of the production profile of PV and the spot
price variation, the market value of the PV electricity and the value factor can be derived [26]. The market value
points to whether the production profile of power generation from a specific energy resource matches the spot price
variation, and is the average of the production share at times the corresponding spot price pt at every specific
timestep t. This is expressed by the equation:


where T is the number of time steps in the examined period. The value factor VF is the market value divided with
the average spot price  in the examined period:






A value factor greater than one indicates that the value of electricity generation exceeds the average spot price for
a certain period (typically one year), and vice versa for value factors under one. A value factor over one for a power
supply indicates that the electricity market is demanding electricity production that is in line with the power supply's
production profile.
As can be derived from Table 19 the market value of PV electricity in Sweden has on average been higher than the
spot prices in Sweden under the time period 2014 to 2019. On average a PV system received 10 SEK more per
MWh than the average spot price. One can also see that the market value of PV electricity is higher in the two
southern price areas (SE3 and SE4) than in the two northern ones (SE1 and SE2). This is fortunate, as the average
global radiation is higher in the southern part of Sweden.

Analysing the value factor of PV, Table 19 show that the value factor has varied over the years. In 2015 and 2019
it was below 1.0, while it was higher than 1.0 in 2014, 2016, 2017 and 2018. The highest value factor was achieved
in 2018, which was also the year with highest global radiation records in Sweden (see section 2.7). High production
and a high value factor do not necessarily have a correlation. The reason for the high value factor and an irregularly
high production by PV in 2018 was actually the low production by other power sources in Sweden, due to the long
periods of anticyclone weather (with high barometric pressure). In the Swedish power mix wind power and hydro
stands for large shares (see Figure 8 and Figure 9), which are both production sources that depend on low
barometric pressure weather, as this typically leads to higher wind speeds and precipitation. Furthermore, the
electricity production from Swedish CHP plants are heavily dependent on heat demand from the well-developed
Swedish district heating networks, and the heat demand was of course very low due to long periods of sunny and
warm weather that year. This led to a situation with much higher electricity prices in the summer, compared to in
the winter.
If one compares the value factor of PV with the value factor of the other power sources [4], one can see that hydro
power, PV and CHP in general has value factors above 1.0, while nuclear and wind power consistently have value
factors below1.0. A simplified conclusion is that the price indicates that the Swedish electricity system would benefit
if production with the production profiles similar to either hydro power, PV or CHP would be added. However, this
does not by default correlate with profitability for these power sources.

As the electricity mix in Sweden changes, (more wind and PV are expected to be built while the two nuclear reactors
at Ringhals 1 and Ringhals 2 face decommissioning as of 30 of December 2019 and 31st of December 2020) the
value factor of the different power sources will change. E.g. in a recent study it was simulated that the value factor
of PV will go from in general being above 1.0 to in general be below 1.0 if PV reaches above 5 % of the total power
production in the electricity mix [27].
Household electricity costs consist of several components. The base is the Nord Pool Spot price of electricity. On
top of that, energy tax, the cost of green electricity certificates, the variable grid charge, the fixed grid charge, VAT
and sometimes an electricity surcharge and a fixed trading fee are added. Figure 15 illustrates the evolution of the
average electricity price for the average end consumer over the years [28]. In Figure 16 the variable part of the
electricity price, which is what can be saved if the micro-producer replaces purchased electricity with self-generated
PV electricity, is illustrated. Furthermore, the value of the excess electricity is shown for two base cases with the
Nord Pool spot price as a base compensation offered by electricity trading utility companies (see section 7.2),
energy compensation from the grid owner (see section 3.3.6), the tax credit system (see section 3.3.5) and with
and without the green electricity certificate, since few PV owners are using the green electricity certificate system
(see section 3.2.3).

family house with electric heating.

32
The reader should note that the electricity price in Figure 16 was the lowest achievable in May 2019, and that most
customers payed more. It is also worth noting that some utility companies offer higher compensations than the Nord
Pool spot price, so with all current possible revenue streams, both the self-consumed electricity and the excess
electricity would have been higher than in the figure.
Global solar radiation
The total amount of solar radiation that hits a horizontal surface is called the global radiation. The global solar
radiation thus consists of the direct radiation from the sun and the diffuse radiation from the rest of the sky and the

remuneration from green electricity certificates.

ground. The solar radiation therefore depends on the weather, on the position on the globe and the season of the
year. The distribution of annual average global radiation over Sweden is presented in Figure 17 [29].
In the long-term variation of global radiation in Sweden a slight upward trend has been noted and the average solar
radiation has increased by about 8 % from the mid-1980s until today, from about 900 kWh/m2 in 1985 to the current
level of the recent years, which has varied between 900–1 000 kWh/m². In 2019 annual average accumulated global
radiation reached 976 kWh/m² [29]. From a PV production perspective, a rather good year, but far below the historic
record of 1050,8 kWh/m2 in 2018, when long periods of anticyclone weather (where barometric pressure is high)
over Scandinavia gave very sunny weather during May and July.
Production costs of PV electricity
The most common way to estimate the production cost of electricity is to calculate the levelized cost of electricity
(LCOE). For calculating the LCOE for PV the following equation can be used;

were Infl stands for the annual inflation rate.
The LCOE of PV electricity very much depend on the size of the PV system and the type of actor owning the system,
as the CAPEX and WACC parameters are the two most influential ones for the end result. In this report the
assumptions made for the LCOE of a small residential BAPV systems on a single-family house (hereafter called
villa systems) is discussed, while preliminary assumptions derived from an upcoming interview study for centralized
PV parks are just listed.
The general lifetime of a villa-system is today unknown as very few PV systems in Sweden (or internationally) have
been operated for longer than 20 years. The PV modules usually have a warranty of 25 or 30 years, which could
be used as an indicator of the economic lifetime. It is difficult to prove that the warranty holds for PV systems in
Swedish climate and determine what the degradation rate is in a northern climate, as very few studies have been
made. But one study made on modules from a PV system installed 1981 on Bullerön showed that the PV modules
degraded 2 % over 25 years [30]. This corresponds to a degradation rate of only 0.08 %/year. It is hard to tell from
just one study if these silicon modules were of very good quality or if the Swedish climate with lower temperatures
give lower module degradation in general. There are some unpublished measurements of old systems that indicate
that the latter holds, so a degradation rate of 0.2 % has been assumed for the LCOE calculations.
With regards to the first-year yield of villa systems in Sweden a study summarizing the actual production of 828
(2017) and 1380 (2018) decentralized PV systems concluded that the average specific yield for Sweden adjusted
to average solar irradiation was 801 kWh/kWp for 2017 and 790 kWh/kWp for 2018. Therefore, we assume a first-
year yield of an average villa system to be 800 kWh/kWp. This number can of course be higher for individual systems
as it depends significantly on local factors such as azimuth, tilt, shadowing effects and geographical location in
Sweden (see Figure 17).
As concluded in section 2.2 the typical villa system price, both estimated by the installations companies and as
average of registration systems in the Swedish direct capital subsidy programme was 14.3 SEK/kWp. Adding the
Swedish VAT of 25 % the final CAPEX then becomes 17.9.
The yearly fixed operation and maintenance costs of villa systems are harder to estimate. It is believed that most
of the homeowner’s take care of the administrative work, follow the PV systems production (electricity monitoring)
and take care of module cleaning without reflecting over the cost of their time. Other typical O&M costs does not
apply to homeowners. E.g. the insurance costs of PV systems are usually covered by the normal home insurance,
there is no additional real estate tax if the PV system is mounted on the roof of a villa and there is usually no
electricity and balancing cost, nor additional annual grid expenses for villa systems. The later because the law
states [31] that an electricity user who has a fuse subscription of no more than 63 amperes and who produces
electricity whose feed in can be made with a power of maximum 43.5 kilowatts shall not pay any fee for the feed in
if the electricity user has extracted more electricity from the grid than he/she has fed in to the grid within a year.
However, some cost estimations associated to the fixed operation and maintenance for homeowners can be made.
One example is that Checkwatt (see section 4.4.1.2) offers a visualization product that includes an alarm if the PV
production falls outside expectations to an annual cost of 420 SEK. This can be viewed as an annual electricity
monitoring service. Furthermore, some utilities charge an administrative fee to handle the initial administration of
renewable certificates (see section 3.2.3) and guarantees of origin (see section 3.3.7). This fee is usually a one-
time fee of about 950 SEK, but it is usually not included in turnkey PV system prices. If this one-time administrative
cost is distributed over the 15 years that one can get renewable electricity certificates and for a 10 kWp system, it
becomes 6 SEK/kWp/a.

Task 1 – National Survey Report of PV Power Applications in Sweden
35
There are usually no variable costs associated to PV system as no fuel is consumed, nor are there any moving
parts that wear out with regards to each kWh produced. However, as initial grid connection cost is included in the
CAPEX and annual fixed grid cost in the O&Mfix a consistent methodology calls for that all variable costs (or income)
from the grid operator is accounted for in the variable operation and maintenance. Hence, the grid benefit
compensation (see section 3.3.6) that a villa system owner receives, can be regarded as a negative variable cost.
The grid benefit compensation typically varies between 0.02 and 0.10 SEK/kWh for different grid operators but
seems to be around 0.04 SEK/kWh on average.
It is usually assumed that the major reinvestment needed to achieve 30 years lifetime of a PV system is a one-time
replacement of the inverters. No Swedish study has been conducted about the future cost of inverters, but from
international studies a common derived price is 25 €/kWp [32][33], which corresponds to 260 SEK/kWp.
The residual value/cost of a PV system is very hard to estimate today, as very few PV systems have been
decommissioned so far. It has been estimated that the global cumulative PV panel waste will amount to 1.7–8
million tonnes by 2030, and that the corresponding total potential material value recovered through PV panel
treatment and recycling could be 450 million USD. Even if the global PV waste streams still are relatively small, an
international recycling industry is starting to take form [34][35]. However, it is still difficult to speculate what the
dismantling costs and recycled material value will be 30 years into the future. A common assumption is that the
value of the material that is possible to recycle correspond to the cost of decommission a system and take care of
all components, which leads to a residual value of 0 SEK in total. This assumption is very uncertain but the best we
can do with the knowledge of today.
The estimation of the WACC for private individuals is also tricky. When it comes to the cost of equity, few people
think about things like discount rate and risk for his/her personal investments. To simplify, we have therefore
assumed a 100 % dept financing and that a PV system is financed through an enlargement of the mortgage loans,
which rates on average was 1.6 % in 2019. As a private homeowner does not pay any corporate tax rate, the
nominal weighted average cost of capital per annum becomes 1.6 %. As the goal of the Swedish National Bank
(Sveriges Riksbank) is to keep the inflation at 2 % [36], the real weighted average cost of capital per annum
becomes -0.4 %.
All LCOE assumptions are summarized in Table 22, and with these assumptions the LCOE of a 10 kWp villa system
becomes 0.74 SEK/kWh. This is with no subsidies whatsoever. If the direct capital subsidy is used, which gives a
20 % rebate on the CAPEX, the LCOE becomes 0.6 SEK/kWh. These 0.6 SEK/kWh in production cost can be
compared with the revenues of the self-consumed electricity and excess electricity in Figure 16 for assessments of
profitability of small residential systems in Sweden in 2019.
With the assumptions for a 5 MWp centralized PV park listed in Table 22, the LCOE becomes 0.43 SEK/kWh.
Comparing this production cost with the market value of PV the last six years in Table 19, it can be concluded that
profitability for a merchant business model would only be reached with spot prices at levels seen in 2018. Hence,
for market of centralized PV parks in Sweden it is still important that additional value to PV electricity is added
through, either subsidies such as the renewable electricity certificates (see section 3.2.3), or by business models
such as PPAs or cooperative owned PV parks (see section 2.4).

3 POLICY FRAMEWORK
This chapter describes the support policies aiming directly or indirectly to drive the development of PV. Direct
support policies have a direct influence on PV development by incentivizing, simplifying or defining adequate
policies. Indirect support policies change the regulatory environment in a way that can push PV development.

National targets for PV
There is no official target for future PV installation in Sweden. However, there exist a political agreement that sets
a goal that Sweden will have a 100% renewable electricity system by 2040, while still planning to be a net exporter
of power. The agreement is not a political stop date for nuclear, but in order to reach the goal, this implies phasing
out the Swedish nuclear reactors that are coming of age and continuously pushing for new renewable energy
production. Many of the introduced legislation changes in the coming years are expected to spring from this political
agreement, and the Swedish PV market will most likely benefit from it.
Direct support policies for PV installations
3.2.1 Direct capital subsidy for PV installations
The current capital subsidy for solar cells was introduced on July 1, 2009. Prior to that, there was support for energy
efficiency in public premises, where solar cells were included as eligible investments that could be applied for. In
this program, PV systems could get 70 % of the installation costs covered and the program got the grid-connected
PV market started in Sweden. The support program for public premises was introduced in 2005 and ended after
2008.
In the beginning of 2009, there was a gap with no direct support for grid-connected PV and the installation rate went
down in 2009, as can be seen in Table 4. However, a new subsidy program was introduced in mid-2009, now open
for all actors [37]. Support rates were 55% for large companies and 60% for all others. Originally, 50 million SEK
was deposited annually for three years. This support program has since been extended, support levels have
changed, and more money has been allocated, summarized in Table 24 and Table 25.

The original program was planned to end by the 31st of December 2011 but has been prolonged several times.
In 2017 the budget was increased even more as the government added 200 million SEK for 2017 and 525 million
SEK for each of the years 2018–2020. Later another 170 million SEK was added to the 2018 budget, summing up
to 1,085 million SEK in total. After the election in autumn 2018 the parliament passed an autumn budget which
decreased the annual budget for the direct capital subsidy to 436 million SEK for 2019. In the spring of 2019, the
new formed government added 300 million SEK to the budget and later another 500 million SEK in the next autumn
budget. At the same time, it was communicated that the original budget for 2020 would be 835 million SEK. In the
spring budget of 2020, another 200 million SEK was added. The budget over the years is summarized in Figure 19.
Since its introduction, the interest in the capital subsidy program has always been greater than the budget allocated.
When the support was introduced the 1st of July 2009, there had been a gap since the 31st of December 2008 when
support for public premises was ended, and many actors were prepared to invest. The 50 million SEK that were
allocated for 2009 were therefore all applied for already in day 3 [38]. Ever since then, the amount of money applied
for each year has been much higher than the allocated budget. Therefore, a long queue to get the subsidy has
arisen as applications do not fall out of the line at the end of a year. When the situation was at its peak in 2016,
average waiting time was on average 722 days, i.e. almost 2 years [38]. The effect of the previous long waiting
times led to that the program not solely stimulated, but also constituted an upper cap of the Swedish PV market.
Until 2011 the new version of the subsidy covered 60 % (55 % for large companies) of the installation costs of PV
systems, including both material and labour costs. For 2012 this was lowered to 45 % to follow the decreasing
system prices in Sweden and was lowered further in 2013 to 35 %. From 2015 the level was decreased to maximum
30 % for companies and 20 % for other stakeholders. From January 1st, 2018 the Swedish government increased
the subsidy level for “others” to 30 % so that all actors had the same level. From the 8th of May 2019 the level has
been decreased to 20 % for all following the decline of PV prices and increase in electricity prices for end
consumers.
In the current version of the statute, funds can now only be applied for if the system costs are less than 37 000 SEK
excluding VAT/kWp. Solar power/heat hybrid systems can cost up to 90 000 SEK plus VAT/kWp. If the total system
costs exceed 1.2 million SEK, capital support is only granted for the part of the system cost that is less than this
value (see Table 25). The 1.2 million SEK cap effectively lowers the subsidy level available for big PV systems. For
example, if a large centralized PV park of 10 MW at a cost of 70 million SEK receives the 1.2 million SEK subsidy,
it will only cover 1.7 % of the total system cost.

1Extract from Boverket's database 2020-05-31. The granted resources are expected payments which may change if the circumstances change in
individual cases.
2The numbers are probably higher for several of the later years, as there is a large delay in the system due to the long ques.
Since the start of the first program in 2006 until the end in 2019, 3 051.58 million SEK had been granted and
2 210.30 million SEK had been disbursed [40]. This capital has supported a total installation of 593.12 MWp so far.
This means that the average subsidy for all PV systems since 2006 to 2019 has been 3.7 SEK/Wp, down from
11.8 SEK/Wp in 2015, 8.9 SEK/Wp in 2016, 5.3 SEK/Wp in 2017 and 4.6 SEK/Wp in 2018.
Listed in Table 25 is the annual installed PV capacity that has received support from the direct capital subsidy as
compared to the statistics of yearly installed grid connect PV capacities. The statistic from direct capital subsidy
program correlates well with the yearly installation statistics, except for 2009, 2018 and 2019. For 2009 it can be
explained with a backlog of installations from the older direct capital subsidy program. The difference in the statistics
for 2018 can probably be related to the switch from sales statistics to collecting the statistics from the grid owner.
The explanation for the incoherence of 2019 is probably a delay in disbursement of support to already
commissioned systems. A general explanation for the higher number of annual installed capacities compared to
yearly PV capacity with support from the direct capital subsidy is that nowadays it is more common to complete the
installation of the PV system without first being granted the direct capital subsidy. This can be seen in the database

Task 1 – National Survey Report of PV Power Applications in Sweden
41
of the program where there are several systems that have a registered system completion date that is earlier than
the granted support date.
3.2.2 Direct capital subsidy program for renewable energy production in the
agriculture industry
In 2015 the Swedish Board of Agriculture (Jordbruksverket) introduced a direct capital subsidy for production of
renewable energy. The subsidy can be applied for if a company has a business in agriculture, gardening or herding.
The subsidy is given to support production of renewable energy for both self-consumption in agricultural activities
and for sale. This may be in the form of biomass, wind, hydropower, geothermal or PV [41].
The subsidy is granted for the purchase of materials, services of consultants to plan and carry out the investment,
but not salary to employees or work done by the applicant. The level of the direct capital subsidy is 40 % of the total
expenses. The maximum amount of aid a company can receive is decided by the respective County Administration
(Länsstyrelse) or by the Sami Parliament (Sametinget) [41].
The support level of this direct capital subsidy is higher than in the national direct capital subsidy program for PV
installation. This can be motivated by the fact that many agricultural companies pay a lower level of the Swedish
energy tax (see section 3.3.1), which makes the value of self-consumed electricity lower than for regular electricity
consumers and therefore a PV system or any other renewable system is less profitable. A higher subsidy level
increases the profitability of PV installations on barns and other agriculture buildings, which is a market segment
with large potential [42].
Until the end of 2019, the program has granted and disbursed support to 101 PV projects with a total capacity of
3 725 kW for a total amount of 15 744 718 SEK, in accordance with Table 26.

3.2.3 The renewable electricity certificate system
The basic principle of the renewable electricity certificate system is that producers of renewable electricity receive
one certificate from the Government for each MWh produced. Meanwhile, certain electricity stakeholders are
obliged to purchase certificates representing a specific share of the electricity they sell or use, the so-called quota
obligation. The sale of certificates gives producers an extra income in addition to the revenues from electricity sales.
Ultimately it is the electricity consumers that pay for the expansion of renewable electricity production as the cost
of the certificates is a part of the end consumers' electricity price. The energy sources that are entitled to receive
certificates are wind power, some small hydro, some biofuels, solar, geothermal, wave and peat in power
generation, and each production facility can receive renewable electricity certificates for a maximum of 15 years
and limited to the end of year 2045.
The quota-bound stakeholders are: electricity suppliers; electricity consumers who use electricity that they
themselves produced if the amount used is more than 60 MWh per year and it has been produced in a plant with
an installed capacity of more than 50 kWp; electricity consumers that have used electricity that they have imported
or purchased on the Nordic power exchange; producers who produce electricity to a grid which is used without

Task 1 – National Survey Report of PV Power Applications in Sweden
42
support of grid concession (nätkoncession), provided the electricity used amounts to more than 60 MWh per year
and if the electricity is commercially supplied to consumers who use the electricity on the same grid; and electricity-
intensive industries that have been registered by the Swedish Energy Agency (Energimyndigheten).
The system was introduced in Sweden in 2003 to increase the use of renewable electricity. The goal of the certificate
system at that time was to increase the annual electricity production from renewable energy sources by 17 TWh in
2016 compared to the levels of 2002. In 2012 Sweden and Norway joined forces and formed a joint certificate
market. The objective then was that the electricity certificate system would increase the production of electricity
from renewable sources by 26.4 TWh between 2012 and 2020 in Sweden and Norway combined. In the common
market there is the opportunity to deal with both Swedish and Norwegian certificates to meet quotas [43]. In March
2015, the Swedish and Norwegian governments made a new agreement that raised the common goal of 2 TWh to
28.4 TWh until 2020. This increase will only be funded by Swedish consumers [44].
Furthermore, in the wake of the broad political agreement on the future Swedish electricity system (see section 3.1)
it was decided in 2017 that the electricity certificate system will be extended to 2030 with another 18 TWh of
renewable electricity. The prolongation involves a linear escalation of the 18 TWh with 2 TWh per year from 2022
to 2030. However, due to the rapid construction of wind power, the Swedish Energy Agency anticipate that the 2030
goal could be reached by as early as 2021 [45]. To avoid that the prices of the certificates drops down to zero due
to over-establishment of renewable energy sources, which would be detrimental to early investors, a new
proposition was circulated on March 18th, 2020. This proposition suggests that no power production constructed
after 2021 will be eligible for certificates, and that the termination of the certificate system be advanced to 2035
rather than the current 2045 end date [46].
In 2019, the average price for a certificate was reduced to 90.5 SEK/MWh from the average price of
145.7 SEK/MWh in 2018 [47] and the quota obligation was increased to 30.5 %, from 29.9 % in 2018 [48]. The
established trend in the level of the quota duties is summarized in Figure 21 and the price trend in Figure 20. Since
the start in 2003 until the end of 2019, certificates corresponding to 294.4 TWh has been issued in Sweden with PV
accounting for 463.7 GWh of them [47].
Figure 21: The quota levels in the renewable electricity certificate system [48].

43
Until 2005 there were no PV systems in the electricity certificate system [49]. However, as Table 27 show, the
number of approved PV installations increased over the years and a majority of the approved plants in the certificate
system are now PV systems. However, these systems only make up for a very small part of the total installed power
and produced certificates. As can be seen in Figure 22, most of the certificates go to wind and biomass power,
which produce more in the winter months. Even after considering the electricity consumption in Sweden, which is
higher in the winter, the allocation of certificates is higher in the winter months. By comparing Figure 22 and Figure
23, it is easy to see the potential for solar to level out the seasonality of certificate issuance. However, the installed
solar capacity would have to increase dramatically in magnitude.
340.1 MW of PV power was accepted in the certificate system at the end of 2019 [49], making it 49 % of the total
installed PV grid connected capacity. As Figure 24a shows, that share has been rather constant over the years.

There are several reasons why it has been difficult for PV to take advantage of the electricity certificate system and
why solar owners refrain from applying. One is that many owners of small photovoltaic systems do not consider the
income that certificates provide worth the extra administrative burden. The main reason for this is that the meter
that registers the electricity produced by a PV system is often placed at the interface between the building and the
grid. This has the consequence that it is only excess production from a PV system that generates certificates and
the solar electricity that is self-consumed internally in the building is not awarded any certificates. A PV owner can
get certificates also for the self-consumed electricity if an internal meter is installed. For smaller PV systems, the
additional cost of such a meter and the annual metering fee can be higher than the revenue from the additional
certificates, which means that many refrains from applying for certificates for the self-consumed electricity. This is
the main reason why the proportion of PV production that receive certificates per year is so low in Table 27 and
why only 181 840 certificates were issued to PV in 2019 [47]. This is only about 29 % of the theoretical production
of 691 MW × 900 kWh/kW ≈ 622 GWh from all grid-connected PV systems in Sweden. The reader should note that
the calculation above is very simplified since the whole cumulative grid-connected PV power at the end of 2019
was not up and running throughout the whole year.
Another reason why it has been difficult for PV to take advantage of the certificate system is that it can be difficult
for an individual to find a buyer for only a few certificates. However, this is about to change as more and more
utilities have begun offering to purchase certificates from micro-producers (see section 7.2). This, and the fact that
the systems are getting increasingly larger as the prices are going down, may be the reason for the clear trend in
in Figure 24b and Table 27 where the share of the produced PV electricity that receives certificates is increasing.
To summarize, the renewable electricity certificate system in the present shape is being used by some larger PV
systems and parks but does not provide a significant support to increase smaller PV installations in Sweden in
general. It is also likely to expect a decision about an earlier termination of the system in the near future.

3.2.4 BIPV development measures
There were no specific BIPV measures in Sweden in 2019.
Self-consumption measures
Self-consumption of PV electricity is allowed in Sweden and is the main business model that is driving the market.
Several utilities offer various agreements for the excess electricity of a micro-producer.
Since the spring of 2014 an ongoing debate about what tax rules that apply to micro-producers has been under
way, and consequently several changes in the different tax laws has occurred since then. Listed in this section are
some specific tax laws that affect self-consumption and micro-producers.

3.3.1 General taxes on electricity
In Sweden, taxes and fees are charged at both the production of electricity and at the consumption of electricity.
Taxes that are associated with the production of electricity are property taxes (see section 3.6.1), taxes on fuels
and taxes on emissions to the atmosphere.
The taxes associated with electricity consumption are mainly the energy tax on electricity and the value added tax
(VAT). The manufacturing and agriculture industry paid 0.005 SEK/kWh in energy tax in 2019. The Energy tax rate
has been increased in steps for residential customers the last couple of years after the Swedish Energy Commission
(see section 3.1) decided to remove the specific tax on nuclear and finance that with a higher energy tax [50]. The
latest increase occurred the first of January 2020 when the energy tax was increased from 0.347 SEK/kWh
(excluding VAT) to 0.353 SEK/kWh. The exception is some municipalities in northern Sweden where the energy
tax now is 0.257 SEK/kWh (excluding VAT) [51]. Additionally, a VAT of 25 % is applied on top of the energy tax.
Altogether, roughly 40 % of the total consumer electricity price (including grid fees) was taxes, VAT and certificates
in 2019.
3.3.2 Energy tax on self-consumption
There has been an ongoing modernization of the Swedish tax rules when it comes to taxation on self-consumed
electricity. The current rules, which were implemented on July 1st, 2017, can be can be summarized as [51]:
• A solar electricity producer that owns one or more PV systems whose total power amounts to less than
255 kWp does not have to pay any energy tax for the self-consumed electricity consumed within the same
premises as where the PV systems is installed.
• A solar producer that owns several PV systems, which total power amounts to 255 kWp or more, but where
all the individual PV systems are smaller than 255 kWp, pays an energy tax of 0.005 SEK/kWh on the self-
consumed electricity used within the same premises as where the PV systems is installed.
• A solar producer that owns a PV system larger than 255 kWp pays the normal energy tax of 0.347 SEK/kWh
on the self-consumed electricity used within the same premises as where the PV systems is installed, but
0.005 SEK/kWh in energy tax for the self-consumed electricity from the other systems if they are less than
255 kWp.
The current legislation has the effect that few PV systems over 255 kWp are built for self-consumption in Sweden.
The full energy tax on self-consumed electricity limits the profitability for those systems. This leads to that the large
technical potential of PV systems within the industrial sector currently is unexploited.
When it comes to systems smaller than 255 kWp the main economic obstacle for real estate owners that plan to
build several small PV systems has been removed with this legislation. However, the administrative burden of
measuring and reporting the self-consumed electricity if the total power limit of 255 kWp is exceeded remains.
However, there is an ongoing discussion on how to tax self-consumption, and it is not unlikely that changes to this
legislation will take place in the near future. One positive prospect in this matter is that the government has declared
their purpose to remove the 0.005 SEK/kWh energy tax for real estate owners that own several small systems, and
thereby remove the administrative barrier, by sending in a state aid notification to the EU Commission [52].
3.3.3 Deduction of the VAT for the PV system
Sweden has a non-deductible VAT for permanent residents. The possibility to deduct the input VAT for a PV system
therefore depends on whether all produced electricity is sold, or if a portion of the generated electricity is consumed
directly for housing and only the excess electricity is sold to an electricity supplier [53].

Task 1 – National Survey Report of PV Power Applications in Sweden
47
If only the excess electricity is sold to an electricity supplier and the PV system also serves the private facility, then
deduction of the VAT for the PV system is not allowed.
If all generated electricity is delivered to an electricity supplier, then the PV system is used exclusively in economic
activity and deduction of the VAT for the PV system is allowed.
However, according to Case 6174-18 of the Swedish Supreme Administrative Court, it is stated that the VAT
deduction waiver for permanent housing does not include homeowner’s association's (BRF) acquisition of PV
systems. The homeowner’s association is granted the right of deduction for VAT as long as the acquisition is
attributable to the association's VAT liable sales of surplus electricity. In summary, this means that a homeowner’s
association may deduct VAT on the investment in a PV system corresponding to the proportion of electricity that
will be sold to the electricity grid.
3.3.4 VAT on the revenues of the excess electricity
A PV system owner that sells the excess electricity will receive compensation from the electricity trading utility
company and from the grid owner (see section 3.3.5). If the total renumeration from the property (including other
revenue streams than selling excess electricity) under a tax year exceeds 30 000 SEK, excluding VAT, the house
owner needs to register for VAT and handle the VAT streams between the utilities that buy the excess electricity
and the tax agency (see Figure 25). If the total annual sales do not exceed 30 000 SEK the PV system owner are
exempted from VAT [54].
At a reimbursement from a utility company of 0.5 SEK/kWh, 60 000 kWh can be sold per year before reaching the
limit. At a self-consumption rate of 50 % it corresponds to a PV system of a size of about 120 kWp. Hence, as a
general rule of thumb, the 30 000 SEK limit corresponds to PV systems of 100–200 kWp, which is a very large PV
system size for regular homeowners.
The limit of 30 000 SEK was implemented the 1st of January 2017 and is an improvement for the Swedish PV
market. In 2016 a private homeowner needed to go through the administration of registering for VAT and reporting
the VAT to the Government. The new set of rules makes it much easier for a household to invest in PV in Sweden.
Furthermore, it has also reduced the administration for the tax agency as it doesn't need to handle the registration
of several thousands of private PV owners. As the Government is not losing any tax income, as illustrated in Figure
25, it is a win-win situation for all parties as compared to before the 1st of January 2017.
3.3.5 Tax credit for micro-producers of renewable electricity
The 1st of January 2015, an amendment to the Income Tax Act was introduced [55]. The tax credit is 0.60 SEK/kWh
for renewable electricity fed into the grid. The right to receive the tax credit applies to both physical and legal
persons. To be entitled to receive the tax credit the PV system owner must:
• feed in the excess electricity to the grid at the same connection point as where the electricity is received,
• not have a fuse that exceed 100 amperes at the connection point,
Figure 25: Illustration of the revenue and VAT streams for the excess electricity for a private PV owner
before and after the 1st of January 2017.

Task 1 – National Survey Report of PV Power Applications in Sweden
48
• notify the grid owner that renewable electricity is produced at the connection point.
The basis for the tax reduction is the number of kWh that are fed into the grid at the connection point within a
calendar year. However, the maximum number of kWh for which a system owner can receive the tax credit may not
exceed the number of kWh bought within the same year. In addition, one is only obliged to a maximum of
30 000 kWh per year. The grid owner will file the measurement on how much electricity that has been fed into and
out of the connection point in one year and the data will be sent to the Swedish Tax Agency (Skatteverket). The tax
reduction will then be included in the income tax return information, which should be submitted to the Swedish Tax
Agency in May the following year.
The tax credit of 0.60 SEK/kWh is received on top of other compensations for the excess electricity, such as
compensation offered by electricity retailer utility companies (see section 7.2), the grid benefit compensation (see
section 3.3.6) and revenues for selling renewable electricity certificates and guarantees of origins (see section 3.2.3
and 3.3.7). The tax credit system can be seen as a feed-in premium for the excess electricity. However, unlike the
case in other European countries, the Swedish tax credit system does not offer a guaranteed revenue over a specific
period. This means that the extra income that a micro-producer receives from the tax credit system when feeding
electricity to the grid can be withdrawn, increased or decreased by a political decision.
According to the Swedish Tax Agency 29 512 micro-producers of renewable electricity received a total 74 884
654 SEK for excess electricity fed into the grid in 2019. This amount is based on 124 807 MWh of excess electricity
fed into the low voltage grid by micro producers, reported by the grid operators to the Swedish Tax Agency. The
average production fed into the grid per micro-producer with a capacity of less 100 amperes was thereby 4 229 kWh
in 2019, as summarized in Table 29.

These numbers contain, not only PV, but all small-scale renewable production. To get an estimation of the share of
PV in the tax reduction one can look at the power of systems that had a production capacity below 69 kW (which
corresponds to the 100-ampere limit of the tax reduction) in the green electricity certificate system. In total there
was 224 677 kW of systems with a power less than 69 kW by 2019-12-31. Of this power 220 111 kW was PV, and
the rest was 2 372 kW wind, 1 235 kW hydro and 959 kW biofuel or peat system [49]. If one uses this relationship,
a rough estimation is that 189 876 695 SEK of the total 193 815 512 SEK has been paid to PV system owners
through the tax credit for micro-production system until the end of 2019. This calculation is just a rough estimation
since both the total produced electricity in a year and the self-consumption ratio differ between the different
renewable energy technologies and between all the individual production facilities.
3.3.6 Grid benefit compensation
A micro-producer is entitled to reimbursement from the grid owner for the electricity that is fed into the grid. The
compensation shall correspond to the value of the energy loss reduction in the grid that the excess electricity entails

Task 1 – National Survey Report of PV Power Applications in Sweden
49
[31]. The compensation varies between different grid owners and grid areas and is typically between 0.02 and 0.10
SEK/kWh.

3.3.7 Guarantees of origin
Guarantees of origin (GOs), were introduced in Sweden on December 1st in 2010, and are electronic documents
that guarantee the origin of the electricity. Electricity producers receive a guarantee from the Government for each
MWh of electricity. The electricity producer can then sell GOs on an open market. The buyer is usually a utility
company who wants to sell that specific type of electricity. Utilities buy guarantees of origin corresponding to the
amount of electricity they would like to sell. GOs are issued for all types of power generation and applying for
guarantees of origin is still voluntary.
When the electricity supplier has bought the GOs and sold electricity to a customer, the GOs are nullified. The
nullification ensures that the amount of electricity sold from a specific source is equivalent to the amount of electricity
produced from that source.

A utility company that wants to sell, for example, electricity from PV can do so in two ways. Either by nullify
guarantees of origin from its own PV-system, or by purchasing guarantees of origin from a PV-system owner and
nullify them when the supplier sells the electricity to the end customer.
The GO act (2010:601) and regulation (2010:853) was changed the first of June 2017 to enable the Swedish Energy
Agency to issue GOs for electricity that can be transferred to another EU Member State [56]. Thus, the Swedish
GO system now has been adapted to the EECS standard.
As a result of the new legislation and due to the increase of PV system the trading with solar GOs in Sweden
increased dramatically, as can be seen in Table 30. In 2017 a lot of solar GOs was imported to Sweden, and in
2018 a lot of them was exported. 2019 is once again seeing an increase in imported solar GOs, along with a three-
fold increase in nullification from the year before.
The trading volumes of solar GOs are still too small in Sweden for the system to really generate an actual market
price. But according to Svensk Kraftmäkling (SKM), the largest brokerage firm in the Nordic electricity market, Solar
GOs were generally traded in Europe for 60 €-cents/MWh in 2019, which would translate to the value 0.006
SEK/kWh. However, some Swedish utilities buy solar GOs issued in Sweden from small-scale PV owners for a
much higher price.

Collective self-consumption, community solar and similar
measures
Collective self-consumption from a PV system in an apartment building is allowed in Sweden if all the apartments
share the same grid subscription. A number of housing companies and housing societies are using this option. The
general approach for such a solution is that the whole apartment building share one electricity contract with the
utility and that the electricity is included in the rent, but that electricity consumption is being measured internally by
the housing company/society and the monthly rent is affected by this consumption.
Collective self-consumption where the electricity is transported over a grid that is covered by a grid concession is
currently not allowed.
Tenders, auctions & similar schemes
There were no national or regional tenders or auctions in 2019 in Sweden. However, commercial PPAs for PV exists
in Sweden.
Utility-scale measures including floating and agricultural PV
There were no specific national or regional subsidies for utility-scale PV in Sweden in 2019. The support and
measures accessible for utility-scale PV are the general support schemes of the direct capital subsidy (see section
3.2.1) but with a cap of 1.2 million SEK per system which lowers the benefits of utility-scale centralized PV parks,
the green electricity certificate system (see section 3.2.3) and the guarantees of origin system (see section 3.3.7).
3.6.1 Property taxes
Power generation facilities in Sweden are charged with a general industrial property tax. Today the PV technology
is not defined as power generation technology in the valuation rules for power production units in the real estate
law (Fastighetstaxeringslagen). The tax agency has so far classified the few large PV parks that exist as “other
building” and taxed them as an industrial unit. Currently the property tax of an industrial unit represents 0.5 % of the
assessed value of the facility [57].
Social Policies
There were no social policy measures directed to PV in Sweden in 2019.
Retrospective measures applied to PV
There are currently no retrospective measures applied to any subsidies for PV in Sweden.
Indirect policy issues
3.9.1 Rural electrification measures
There were no rural electrification measures in Sweden in 2018.
3.9.2 Exemption for building permits for solar energy systems
As from the first of August 2018 PV and solar thermal system installations on buildings are exempted from building
permits in general. Some installations still require building permits, and that is when the one of following situations
applies [58]:
• When the PV or solar thermal system does not follow the shape of the current building.
• When the PV or solar thermal system is installed within a residential area that is classified as valuable
from either a historical, cultural, environmental or artistic point of view.

Task 1 – National Survey Report of PV Power Applications in Sweden
52
• When the PV or solar thermal system is installed within a residential area where the municipality in the
detailed development plan defined that building permits are required for solar systems.
• When the PV or solar thermal system is installed within an area that are of national interest for the military.
Maps over these areas are located can be found here.
In these cases, a regular building permit must be submitted to the municipality.
3.9.3 Direct capital subsidy for storage of self-produced electricity
To help increase individual customers possibility to store their own produced electricity the Swedish Government
has introduced a direct capital subsidy for energy storage owned by private households. The subsidy is given for
energy storages that fulfil these criteria [59];
• connected to an electricity production system for self-consumption of renewable electricity,
• connected to the grid,
• helps to store electricity for use at a time other than the time of production,
• which increases the annual share of self-produced electricity used within the property to better meet the
electricity consumption.
The state aid is not given to installations of storage that has received the ROT tax deduction (see section 3.9.7) or
any other public support. Eligible costs are the costs of installing electrical energy storage systems, such as
batteries, cabling, control systems, smart energy hubs and installation work. The subsidy is only granted to
individuals with a maximum of 60 % of the eligible costs, but no more than 50 000 SEK [59].
For other end consumers than private households, that want to invest in PV with storage, the storage can be
included in the overall system cost in the regular direct capital subsidy for PV (see section 3.2.1)
The state aid for storage program was introduced in November 2016, but all storage installations that meet the
criteria and were installed in 2016 are entitled to apply for the subsidy. The budget for the storage subsidy program
is 25 million SEK for 2016 and 50 million per year for 2017 to 2019. However, the budget for this subsidy has not
been used in any single year. The total granted and disbursement of funds as of the end of 2019 was
51 766 639 SEK and 23 817 471 SEK, respectively.
3.9.4 Future aggregated grid subscriptions
From 2021 it will be possible to subscribe for aggregated grid contracts for connection points in areas where
Svenska Kraftnät previously refused increased grid connection capacities. The prerequisite is that there are
connection agreements for the points and that it is technically possible to connect them. An aggregated subscription
means that the grid customer is given the opportunity to transfer power between the different connection points that
are included in the aggregated subscription. These can be used to alleviate the situation in areas where there is a
lack of grid capacity. The change is being implemented in the existing tariff structure in order to be able to facilitate
the rapidly emerging markets relatively quickly.
3.9.5 Support for electric vehicles
3.9.5.1 The Bonus-Malus systems
The Bonus Malus system was introduced the 1st of July 2018 to replace the previously existing system of five-year
tax exemption for vehicles classified as a green vehicle.
The main cause for the new law was to increase the share of vehicles with low carbon footprint and to lower the
dependency of fossil fuels in the fleet of vehicles. For cars and light trucks taken into use from the 1st of July 2018,
an individual can get up to 60 000 SEK as a capital subsidy. For every gram of carbon dioxide per kilometre that
the vehicle emits, the bonus is reduced by a set amount. If the vehicle was sold and taken into use prior to 2020,
the bonus is reduced by 833 SEK per additional gram. For vehicles taken into use in 2020 or later, the bonus is
reduced by 713 SEK per additional gram. The lowest bonus was 10 000 SEK at 60 gCO2/km and from there the

Task 1 – National Survey Report of PV Power Applications in Sweden
53
bonus ceases. However, as of 2020, the lowest bonus can now be obtained for vehicles with emissions at 70
gCO2/km. Furthermore, the maximum bonus cannot exceed 25 percent of the vehicles’ price [60].
A company can also get a bonus. However, for companies it is up to 35 percent of the price difference between the
price of the low emitting vehicles’ and the price for the closest comparable vehicle [61].
For petrol- and diesel-powered vehicles, an increased vehicle tax (malus) is added for the first three years. The tax
increase is based on how much carbon dioxide the vehicle emits. If the vehicle emits 96-140 gCO2/km the tax
increase is 82 SEK per gram carbon dioxide emitted per kilometre. If the vehicle emits more than 140 gCO2/km the
tax increase is 107 SEK per gram carbon dioxide emitted per kilometre.
For 2019, there was 1.28 billion SEK administered by the Swedish Transport Agency [62]. Year 2020 has an
increased budget of 1.76 billion SEK.
3.9.5.2 Subsidies for charging infrastructure
To favour the development of the electrical vehicle market it is important to create a liable charging infrastructure.
In 2015 a capital subsidy (Klimatklivet) was established, aimed at supporting local and regional investments that
lower carbon dioxide emissions. The grant is administered by the Swedish Environmental Protection Agency
(Naturvårdsverket) and can be applied by everyone besides private individuals. Investments in charging
infrastructure is one of the types of projects that can be subsidised. Since 2015 to 2019, 2061 charging infrastructure
projects have been granted adding up to 409.7 MSEK [63]. The grant is up to 50 percent of the eligible costs [64].
Eligible costs are the costs needed to achieve the objectives of the project. A basic requirement for the cost to be
eligible is that it must be necessary for the implementation of the project.
From 2015 the applications for Klimatklivet could be granted for charging infrastructures for both public and private
use. But in 2019 another type of grant was established for charging infrastructure for private persons [65]. The
capital subsidy for private charging infrastructure is also administrated by the Swedish Environmental Protection
Agency (Naturvårdsverket) but will no longer be a part of Klimatklivet. This new subsidy program was implemented
to make the application procedure easier. The capital subsidy is up to 50 percent of the eligible costs, however,
there is a maximum of 15,000 SEK per charging point. Eligible costs are the material and labour costs that are
needed to install the charging point, such as the cost for the charging box and for the electrical wiring. Costs that
has received any other public support do not qualify as eligible costs [65].
In December 2017 the government decided to implement a grant for investments in charging infrastructure for
electrical vehicles. The grant (Ladda-hemma) is only given to private individuals and the charging point must be
installed on a property that the applicant owns [66]. The grant is up to 50 percent of the eligible costs, however,
there is a maximum of 10,000 SEK per property. Eligible costs are the material and labour costs that are needed to
install the charging point, such as the cost for the charging box and for the electrical wiring. Labour costs that have
received the ROT tax deduction (see section 3.9.7) or any other public support do not qualify as eligible costs [66].
In 2019 the grant (Ladda-hemma) for charging infrastructures was renamed to “Ladda bilen” and was extend so
that also companies, housing cooperatives and municipalities can apply for money. A single home can still get up
to 10,000 SEK, while other actors can get up to 15,000 SEK per charging point.
3.9.6 Curtailment policies
There were no rules when it comes to curtailment of renewable electricity in Sweden in 2018.
3.9.7 ROT tax deduction
The ROT-program is an incentive program for private persons that buy services from the construction industry in
Sweden in the form of tax credits. ROT is a collective term for measures to renovate and upgrade existing buildings,
mainly residential properties. Reparations and maintenance as well as conversions and extensions are counted as
ROT work and are therefore tax deductible, provided that such work is carried out in close connection with a
residence that the client owns and in which he or she lives, or if it is a second home, like a recreational
summerhouse [67].

Task 1 – National Survey Report of PV Power Applications in Sweden
54
The ROT-tax deduction in 2019 was 30 % of the labour cost and of maximum 50 000 [67] for the installation of a
PV system. The requirements are that the house is older than five years and that the client has not received the
direct capital subsidy for PV. Installation or replacement of solar panels are entitled ROT, while services of solar
panels are not.
According to the Swedish Tax Agency labour costs are estimated at 30 % of the total cost, including VAT. The total
deduction for the whole PV systems was therefore 9 % in 2019. If it can be proved that the labour costs constitute
a higher proportion than 30 %, the total deduction then consequently becomes higher.
The upside of the ROT-tax deduction scheme is that there is no queue and that the PV owner can be sure of
receiving this subsidy. Some homeowners therefore install their PV systems with the ROT tax deduction and later
pay this back to the Government if they receive the direct capital subsidy for PV.
Financing and cost of support measures
In the first version of the direct capital subsidy program 142 531 152 SEK were disbursed and in the second version
a total of 2 072 296 562 SEK has been disbursed from 2009 to the end of 2019 (see section 3.2.1). This system is
financed by the Swedish state budget and the money is distributed by the 21 county administrations.
In addition, the direct capital subsidy for renewable energy production in the agriculture industry program has under
2015–2019 granted a total support of 15 744 718 SEK to PV systems (see section 3.2.2). This system is financed
by the European Agricultural Fund for Agricultural Development (EJFLU), meaning the funding comes from the
European Union.
Furthermore, PV systems have benefited from the renewable electricity certificate system and had at the end of
2019 received a total of 463 720 certificates over the years (see section 3.2.3). By taking the monthly average prices
for the certificates and multiplying these prices with the number of certificates that has been issued to PV in each
month the total support to PV by the end of 2019 becomes 53 434 745 SEK [47]. The renewable electricity certificate
system is financed by electricity consumers, except for electricity-intensive industries that have certificate costs only
for the electricity that is not used in the manufacturing process.
Finally, a rough estimation is that a total of 189 876 695 SEK (see section 3.2.7) has been paid to small scale PV
system owners through the tax credit for micro-producers of renewable electricity subsidy under 2015–2019. This
subsidy financed by the Swedish state budget.
Adding all the above subsides the Swedish PV market had at the end of 2019 in total received about
2 458 million SEK in direct subsidies.

4 INDUSTRY
The Swedish PV industry mainly contains of small to medium size installers and retailers of PV modules or systems.
At the writing of this report the author was aware of 314 companies that sold and/or installed PV modules and/or
systems in the Swedish market (see section 4.6) in 2019. In addition, the author was also aware of 41 consultancy
firms working with different aspects of PV in Sweden (see section 4.7).
With regards to the upstream industry there were 2 active module producers in Sweden in 2019 (see section 4.3),
even if the production volumes were small, and 12 companies active in manufacturing of production machines or
balance of systems equipment (see section 4.4). Furthermore, the author was aware of 11 companies that can be
classified as R&D companies, or companies that had R&D divisions in Sweden (see section 4.5) in 2019.
Unfortunately, there is a trend of fewer and fewer upstream PV industry companies in Sweden. Several Swedish
module manufacturers shut down or went bankrupt around 2010-2012, namely ArticSolar, Eco Supplies, Latitude
Solar, PV Enterprise and REC Scanmodule. In recent years several Swedish start-ups, R&D companies and
manufacturers of BoS products have been forced to close down, e.g. Optistring Technologies AB (in 2017), Box of
Energy AB (in 2018), Sol Voltaics AB (2019), Solibro Research AB (in 2019), Solar Wave (in 2019), and Solarus
Sunpower AB (in 2020).
4.1.1.1 Svensk Solenergi
Svensk Solenergi is a trade association which, with about 260 professional members, representing both the
Swedish solar energy industry and market as well as the research institutions active in the solar energy field. Since
the Swedish PV market is still rather small, the association's resources have so far been rather limited. However,
the organisation is growing, and the activity is increasing.
Production of feedstocks, ingots and wafers
Sweden did not produce any feedstock or wafers in 2019 and there are currently no plans for this kind of production
in the future.
Production of photovoltaic cells and modules
Module manufacturing is defined as the industry where the process of the production of PV modules (the
encapsulation) is done. A company may also be involved in the production of ingots, wafers or the processing of
cells, in addition to fabricating the modules with frames, junction boxes etc. The manufacturing of modules may
only be counted to a country if the encapsulation takes place in that country.
In the beginning of 2011, there were five module producers in Sweden that fabricated modules from imported silicon
solar cells. In the acceleration of PV module price reductions on the world market in 2011 and 2012 the Swedish
module manufacturers struggled (along with the rest of the module production industry) and at the end of 2012 only
SweModule AB of the Swedish companies remained in business. In 2015 also SweModule was filed for bankruptcy,
and there is no longer any large-scale module production in Sweden. Renewable Sun Energy Sweden AB, who
bought the production equipment and the brand SweModule produced 1 MW of commercial modules as part of their
product development in 2019. Furthermore, CIGS thin film equipment manufacturer Midsummer AB inaugurated a
BIPV production line in Sweden in October 2019 and did produce some BIPV modules that same year. In total
1.36 MWp of modules where therefore produced in Sweden in 2019. However, both SweModule And Midsummer
has announced plans to produce larger quantities in 2020.
Total PV cell and module manufacturing together with production capacity information is summarised in Table 31
below.

4.3.1.1 Midsummer AB
Midsummer is a supplier of equipment (further described under the section 4.4.1.6) for manufacturing of CIGS thin
film flexible solar cells as well as a developer and producer of thin film solar panels. Under the trademark
Midsummer Solar Roofs, they sell integrated solar roofs with a focus on design and functionality. Today they have
three products: Midsummer SLIM — long CIGS modules integrated directly onto regular standing seam metal roofs,
Midsummer WAVE — flexible solar panel that follows the wave shape of Sweden’s most popular roof tile and
Midsummer BOLD — 60-cell thin film CIGS solar panels for applications on membrane and metal roofs. Typically,
Midsummer BOLD modules are installed on factories or warehouses which usually can’t handle the weight of
conventional panels. Another popular market is that for sport halls and arenas. Midsummer SLIM and Midsummer
WAVE are focused on the residential market.
Midsummer also has a sheet metal production line which they ramped up under 2019. The thin film solar panels as
well as the production of sheet metal, with or without solar cells, for roof applications takes place in Järfälla. They
are now aiming to expand from the local production in Järfälla, Sweden to multiple facilities in Europe.

4.3.1.1 SweModule
Module production has taken place in Glava, Värmland since 2003 when REC ScanModule AB built a module
production facility there. In end of 2010 REC ScanModule AB closed down their production, but the facilities were
taken over by SweModule AB that continued to produce modules from imported silicon solar cells. In 2015
SweModule went bankrupt. In total, over 2 500 000 multi crystalline silicon modules, corresponding to 500 MW,
have been produced at the site since 2003. However, it seems like these numbers will increase in the coming years
as the production facilities in September in 2016 were acquired by the newly formed company Renewable Sun
Energy Sweden AB. The company begun with refurbishment and repairing of some of the equipment in 2016 and
in 2017 the equipment was upgraded to be able to produce monocrystalline modules with four- and five-busbars.
Under 2018 the certification process of their four- and five-busbars modules was finalised, and the factory is now
ready to produce larger quantities. Under 2016, 2017 and 2018, small quantities of approximately 100, 250 and 500
modules respectively were produced to test the equipment. In 2019, the company produced about 3 000 modules,
which was sold mainly to the Swedish and African PV market.
4.3.1.2 Windon AB
Windon was started in 2007 after a year of product development of different PV equipment. In 2011 Windon became
an OEM by producing PV modules with its own brand in SweModules production facility in Glava, Sweden. Since
the closure of the production facility in Glava in 2015, the company first moved their OEM production of modules to
a factory in Poland, but since the beginning of 2017 almost all of Windons modules are produced on two production
lines in a facility in northern Italy by Windon’s own staff. For 2020 Windon plans to expand their module production
by also producing some quantities in Latvia in addition to the production in Italy. In addition to the module production
the company also produces mounting material and inverters (see section 4.4.1.12).

4.4.1.2 Checkwatt AB
Emulsionen Ekonomiska Förening has for many years been offering a metering system, which includes equipment
and an IT system to micro-producers so they can receive the green electricity certificate system (see section 3.2.3)
for the self-consumed electricity as well. The system sits directly by the solar or wind power inverter and reports the
gross production for allocation of certificates. In 2017 the consultant company Emulsionen placed their metering
concept in the newly formed Checkwatt AB so that this company could solely focus on the metering business.
The actual meter of Emulsionen/Checkwatt is manufactured in China, but the company assembles the data logger
in Sweden. In total Emulsionen/Checkwatt has sold about 2 000 units over the years. Of these around 800 were
sold under 2018. Under 2017 Checkwatt also developed their product so that the meter and the IT system are
compatible with the data that the grid operator have and to data provided by solar radiation sensors. Among other
services, Checkwatt offers; Power meters – MID-certified with gateway communicating with cloud server and
associated visualisation and monitoring services, management of Green Electricity Certificates and Guarantees of

collection from DSO of client’s electricity production and consumption, solar irradiance sensors for precise solar
photovoltaics system evaluation and Solmolnet – tailor made IT system providing data management of metering
and photovoltaics solar production for electricity retailers.
4.4.1.3 Comsys AB
PV modules produces DC current, which in traditional systems is converted via inverters to AC current. The AC
current is in most installations later converted back to DC to run different applications such as lighting systems,
servers, routers etc. Comsys, formerly Netpower Labs, is a company that develops DC-based backup power
systems for data centres and tele-/datacom systems. They have developed hardware and a concept with DC-UPS
systems with integrated PV regulators for running servers and lighting systems directly on DC current without
conversions, thereby reducing the losses significantly. Comsys also has a product called ADF, which remove
interference from the grid through AC filters.
The production of the components occurs at two locations in Sweden, Malmö and Söderhamn. The interest in DC
current powering data centres, commercial buildings and lighting systems is increasing, which probably means that
interest of using PV in these kinds of systems will be become more and more attractive. Comsys has installed the
DC power system in more than 30 data centres and commercial buildings since 2011, 10 of which have integrated
PV. In addition to data centres in 2019 Comsys helped a metal manufacturer in Gnosjö, Sweden, with installing a
DC micro-grid which can go into island mode at the event of a power outage. This system is complete with a 100
kW PV system and batteries that can run the factory’s servers and other critical equipment for 8 hours.
4.4.1.4 Ferroamp Elektronik AB
Ferroamp was founded in 2010 and has developed a product that they call an EnergyHub. The EnergyHub
technology offers a new system design that enables a better utilization of renewable energy in buildings by
introducing a local DC nanogrid ecosystem with smart power electronics. PV solar production and energy storage
is closely integrated on a DC grid, reducing conversion losses as solar energy is stored directly in the batteries
without multiple conversion steps as common in traditional system designs. The EnergyHub offers cost effective
backup power functionality for selected DC loads such as servers, LED lights and DC fast charging of electric
vehicles. Ferroamp has also developed a platform for energy efficiency measures with a service portal for partners
and customers, which extends operation hours to nights and winter months with dynamic power peak management
and selective load control. During 2019 the company supplied its DC grid technology for the world's largest DC
powered office building in Gothenburg including 180 kW PV, 230 kWh energy storage, 100 kW HVAC system and
1 500 luminaires all powered by 380/760 VDC.
In 2014 Ferroamp reached a milestone as they started the shipment of their EnergyHub ACE system for energy
efficiency, hence going from a solely R&D company to a production company. In the end of 2015 Ferroamp released
its PV solar and energy storage solutions. The battery cells come from China, but the production and mounting of
all the components takes place in Sweden. Shipments of scalable PV solar and Energy Storage solutions started
in 2016. 2018 started with a listing on Global Clean Tech top 100 list for game changing technologies and in June
2019, Ferroamp won the 2018 Intersolar Smarter E Award for its PowerShare technology. PowerShare allows
buildings to share PV solar, energy storage and EV charge control via a local DC grid. Benefits include increased
self-consumption, better utilization of energy storage and the potential to create Local Energy Communities with
controlled energy flows.
Ferroamp currently has 20 such DC grids in operation in Sweden. The company has installed over 1 000 systems
to date ranging from small residential systems to larger commercial facilities with integrated PV solar up to 300 kW
and Energy Storage of 300 kWh.
4.4.1.5 MAPAB

they have nearly 200 employees located in Sweden and the US. They produce their solutions locally in the
company's factory in Sweden. The target markets for their products are home and small-scale storage, smart grid
infrastructure, and commercial and industrial support. Nilar produce fully recyclable batteries, free of cadmium,
mercury and lead. The patented Nilar Hydride® battery is based on a bi-polar design, where cells are laid
horizontally and stacked on top of one another to gain space efficiency. By placing their flat cells in a layered
structure in their building block the battery packs that can be varied in sizes.
Nilar, together with Ferroamp, has developed a complete solution that integrates energy storage with power
electronics which facilitates both installation and utilization of the systems. Nilar also works closely with Enequi.
Enequi’s technology works by harvesting the energy when it’s available either from PV or at a low cost from the
grid. The energy is then stored in the built-in Nilar battery packs that can allocate and manage the total energy
needs of the property.
During 2019 Nilar launched an energy storage solution to meet the growing demands from the residential market.
The new cabinet is powered by 6 kWh of Nilar Hydride® batteries. It allows the user to take full advantage of peak
shaving and time shifting applications. During the same year, Nilar delivered more than 200 systems.

focus is on off-grid systems. These inverters are then manufactured in China. They observed a growing interest in
solar energy projects in the telecom and regional rail transit market in 2019 and expect the growth to continue.
4.5.1.3 Epishine
Epishine was founded 2016 with the aim to commercialize organic polymer solar cells. They are a spin-off from
Linköping University based on decades of research resulting in process break-troughs that they think is part of the
tipping point for printed OPV, where global research simultaneously has proven interesting performance and life-
length.
Their first manufacturing site in Linköping focuses on small modules optimized for indoor ambient lighting, targeting
the growing number of battery-driven wireless products, specifically the IoT-market where Epishine initially focuses
on replacing batteries in low power devices such as sensors and consumer electronics.
The manufacturing process, although on a small scale, is constructed as a roll-to-roll process with a conscious
focus on establishing manufacturing methods that can be scaled up to larger formats in the next step that will target
the BIPV-market.
4.5.1.4 Exeger Sweden AB
Exeger is one of the companies in the world that has made the most progress in commercializing the dye-sensitized
solar technology. Already in 2014 Exeger demonstrated that the solar cells could be produced by screen-printing.
The product they have developed is called Powerfoyle, and the material is engineered to generate power with indoor
light and indirect sunlight.
Since 2014 Exeger have been building the world's largest DSC production plant located in Stockholm. In this
production facility Exeger print lightweight flexible and aesthetic solar cells that can be integrated into products such
as consumer electronics, automobile integrated photovoltaics, building integrated and building applied
photovoltaics. In 2016 Exeger worked with several partners to develop commercial consumer electronics
prototypes. Fortum also invested 5.2 million Euros in the company, which enabled Exeger to increase their
production capacity in their new factory from 10 to 15 million units of e-reader sized cells annually. Furthermore,
Exeger received further investment from Softbank in 2019, which enabled planning of a second factory. The
company also entered an agreement with ABB that will design the production robots for the second factory.
In 2019 JBL launched solar powered self-charging headphones with integrated Exegers cells. The company also
announced a collaboration with POC, with the aim of integrate Exegers cells into smart helmets. The production of
these products was planned to start in late 2019, but due to the close down of the Chinese industry at that time (in
an effort to control the COVID-19 outbreak) the production has been post-pone. Exeger has however been ready
to deliver the cells for these headphones and helmets during this period.
4.5.1.5 Peafowl Solar Power AB
Peafowl Solar Power is a spin-off company from Uppsala University developing a new kind of plasmonic solar cell
technology. The solar cells are highly transparent and suitable for outdoor and indoor usage. The current focus is

4.5.1.7 Solarus Sunpower Sweden AB
Solarus is a solar energy company with their roots in Sweden. The company has two different solar panel product
lines, one thermal and one combined PV and solar thermal. Their systems use modules that in part receive direct
sunlight and in part receive focused light from a reflective trough mounted underneath the module. The energy from
the sunlight is collected by water pipes and/or solar cells on the backside and on top of the modules. The commercial
focus lies on the PV/T module, which produces 230 W of electricity and 1 200 W heat under peak conditions. In
2014 Solarus moved to new R&D facilities in Gävle and also started to build a larger production facility in Venlo in
the Netherlands. This production facility is owned by the Dutch sister company Solarus Sunpower BV. The
production was ramped up in 2015 and around 400 PV/T modules was produced in the first year. This number
increased to around 700-800 PV/T modules in 2017. In total, the plant has a production capacity of 30 000 modules
per year. During 2017 the PV/T module stared a testing process at TÜV and Solarus Sunpower started installing
their PV/T solar systems on several hotels in South Africa. The systems perform according to expectations and in
some cases even better than expected. Solarus Sunpower AB filed for insolvency in the beginning of 2020 and
started ramp down business in 2019.
4.5.1.8 Solibro Research AB
The CIGS thin film solar cell company Solibro started as a spin-off company from Uppsala University and Solibro
was in September 2012 acquired from Q-cells by Hanergy, a Chinese group focused on power production. From
September 2013 Solibro Research was owned by Hanergy Thin Film Power Group Ltd. Solibro gResearch AB was
put into liquidation, along with all the other Solibro companies in the group, at the end of 2019.
The task of Solibro Research AB was to further develop the Solibro technology. In 2014 the company achieved a
new world record for the efficiency of a thin film solar cells of 21.0 %. Solibro beat its own internal record, in 2017,
by producing a small-scale CIGS cell with a conversion efficiency of 22.9 %.
In 2017 Solibro Research also started a new development project with perovskite solar cells and thin film tandem
solar cells with a perovskite layer on top of a CIGS layer. During 2018 the research started reaching competitive
levels and in 2019 they managed to produce a CIGS cell with perovskites on top with a conversion efficiency of
23.6 %. This technology and knowledge will live on as several senior employees of former Solibro Research in the
beginning of 2020 started the start-up Evolar AB. This company will further develop the technology of putting
perovskites on top of different type of solar cells (not only CIGS) to achieve higher conversion efficiencies.
4.5.1.9 SolTech Energy Sweden AB
Stockholm based Soltech Energy Sweden is listed on Nasdaq First North Growth Market and develops and sells

China, where they sold and installed about 139 MW until the end of 2019 through their joint venture company ASRE.
4.5.1.10 Sol Voltaics AB
Sol Voltaics was a company that developed methods of improving the efficiency of solar cells by the use of thin film
of nanowires. The company filed for bankruptcy in the beginning of 2019. For further information about the
company’s previous activities, please check older versions of the Swedish National Survey Report.
4.5.1.11 Swedish Algae Factory
Swedish Algae Factory was founded in 2014 around the discovery of the traits of certain diatom species. This
specific trait is their ability to harvest light in a very efficient way through their nanostructured silica shell. The

Task 1 – National Survey Report of PV Power Applications in Sweden

company has developed an algae cultivation and wastewater treatment system from which they harvest this silica
frustule of the algae. The actual organic algae biomass that is left after the extraction of the silica frustule, could be
utilized in several applications such as for feed production or energy and organic fertilizers. The silica material on
the other hand has been identified as a higher value product and in 2016 the company started to test this material's
ability to enhance the efficiency of solar cells. Initial lab tests have shown that the nanostructured silica material can
be utilized to enhance the efficiency of silicon solar panels with over four relative percentage, due to its light trapping
and light manipulating properties.
Under 2017 the company started product testing together with partners to further test this material’s ability to
enhance the efficiency of silicon solar panel by being incorporated into coatings in and on silicon solar panels,
reaching an enhancement of 5 % in panel efficiency so far. The company also further validated the potential of the
material to enhance the efficiency of DSSC (dye sensitized solar cell) and concluded in 2019 in an article a potential
of over 38 %. In 2018 Swedish Algae Factory built a large pilot facility with a yearly production capacity of 300 m2
diatoms in Kungshamn, Sweden. The company will in 2020 start to build commercial production plant with a capacity
of up to 3000 m2, which is planned to be finalized in 2021.
Meanwhile they are developing two types of commercial products. One is to use their material as coatings in PV
modules during the actual production of the modules. The other is to offer retrofit coatings on top of the glass of
already installed modules, as a way of increasing the performance of old modules.

5 HIGHLIGHTS OF R&D
PV research groups
The Swedish solar cell related research consists largely of fundamental research in new types of solar cells and
photovoltaic materials. Several of the research groups in this category are at the forefront and are highly regarded
internationally. Furthermore, there are some smaller groups that focus on PV systems and PV in the energy system-
oriented research. In the table below the different Swedish PV or battery research groups are summarized.

Public budgets for PV research
The majority of the Swedish government's funds to PV research are distributed by the Swedish Energy Agency
(Energimyndigheten), which is tasked with leading the energy transition in Sweden, and the Swedish Research
Council (Vetenskapsrådet). Other organizations that can dispense Governmental money to PV related research are
The Swedish Governmental Agency for Innovation Systems (VINNOVA) and The Swedish Foundation for Strategic
Research (SSF).
6 PV IN THE ECONOMY
This chapter aims to provide information on the benefits of PV for the economy.
Labour places
With the bankruptcy and shut down of several of the Swedish PV module factories in 2010 and 2011 the number of
labour places in the Swedish PV module production industry decreased dramatically. However, the number of
people involved in selling and installing PV systems is increasing as the Swedish PV market grows. The growing
market also leads to an increased involvement from the utility companies, consulting firms and real estate owners.
In many companies and research institutes several people work only partly with PV related duties. The number of
PV related jobs summarized in Figure 28 and Table 33 is an assembly of all the reporting stakeholders' estimations
over how many full-time jobs the Swedish PV market employs at their company. The figures are therefore just
estimations.
By summarizing the labour places related to the actual Swedish PV market, i.e. PV system installers and retailers,
utilities, consulting firms, real estate owners and building companies, and divide it with the annual installed PV
capacity, one can get an estimation of how many labour places that is created per installed PV capacity. As Table
34 shows, the estimated number of created labour places per installed MW was 7.9. A clear trend of fewer and
fewer created labour places per installed MW can also be seen, which cannot be explained by changes in general
system sizes (as Table 6 shows). The reason is probably that the companies are becoming bigger and more
effective in their installation process. The decreasing created labour places is probably one of the reasons for the
declining PV prices in Sweden (See section 2.2).

7 INTEREST FROM ELECTRICITY STAKEHOLDERS
Structure of the electricity system
In Sweden electricity is transported from the major power stations to the regional electricity grids (40–130 kV) via
the national grid (220 kV and 400 kV). From the regional grids, electricity is transported via local, low voltage grids
(40 kV or less) to the electricity consumers. The voltage in the wall sockets in Sweden is 230 V.
The backbone of the electrical grid, the national grid, is owned by the Swedish state and managed by the Swedish
National Grid (Svenska Kraftnät), whereas power utility companies own the regional and local grids. The Energy
Markets Inspectorate (Energimarknadsinspektionen) is the regulatory authority over the electricity market. Since
the grid is a monopoly, there is only one network owner in each area that is licensed.
The base price of the electricity is daily set by the Nordic electricity retailing market, Nord Pool. Electricity trading
companies then use this price as basis for their pricing in the competition for customers. The Swedish electricity
market was deregulated in 1996, which resulted in that the customers could change their electricity supplier more
easily.
There was 134 electricity trading companies and 173 grid owners in Sweden in 2017 [68]. However, the Swedish
grid market is dominated by Vattenfall, E.ON and Ellevio that covers 52 % of all customers. The retail market is
dominated by three companies; Vattenfall, Fortum and E.ON, which together have 56 % of all customers.
Interest from electricity utility businesses
Several utility companies startedmarketeing small turnkey PV systems suited for roofs of residential houses in 2012.
The utility companies that the author is aware of that offered these kinds of turnkey PV systems in 2019 were:
Affärsverken Karlskrona, Bixia, C4 Energi, Dalakraft, E.ON, Enkla Elbolaget, ETC El, Fortum, Fyrfasen Energi,
Gislaved Energi, Gotlands Elförsäljning, Gävle Energi, Jämtkraft, Jönköping Energi, Kalmar Energi, Kraftringen,
Kungälv Energi, LEVA i Lysekil, Luleå Energi, MälarEnergi, Mölndal Energi, Nossebro Energi, Piteå Energi, Sala-
Heby Energi, Sandhult-Standareds Elektrisk, SEVAB Strängnäs Energi, Skellefteå Kraft, Skånsk Energi, Sollentuna
Energi & Miljö, Stockholm Exergi, Storuman Energi, Switch Nordic Green, Södra Hallands Kraft, Telge Energi,
Tekniska Verken i Linköping, Trollhättan Energi, Umeå Energi, Upplands Energi, Utellus, Varbergs Energi,
Vattenfall, Västra Orust Energitjänst and Öresundskraft. These utility companies are also listed as retailers of PV
systems in section 4.6. Most of these utilities collaborate with local Swedish installation companies that provide the
actual system and execute the installation. Only a few of them have the installation competence and product
distribution lines in-house.
One utility company, Umeå Energi also offer leasing of PV system to private persons.
Furthermore, in 2011, several utility companies started introducing compensation schemes for buying the excess
electricity produced by micro-producers. This trend continues, as more and more utility companies now have various
offers for the micro-producer's excess electricity, their green electricity certificates and guarantees of origin. The
offers and compensation vary between the utilities. Most of them have in common that the demand that the micro-
producer is a net consumer of electricity during a year and that they buy their electricity from the utility company.
Some buy the GO's and the green electricity certificates, while some don't. The overall compensation from utilities
for the electricity, plus GO's and the green electricity certificates, varies between 0.25 and 0.70 SEK/kWh. Some
utilities offer even higher compensation if the customer buys the PV system from the company.
Since 2014 a few utilities have started to work with centralized PV parks. Since there are no subsidies for large-
scale PV parks in Sweden, except for the green electricity certificate system (see section 3.2.3) and the maximum
1.2 million SEK from the direct capital subsidies (see section 3.2.1), the proactive utility companies that have started
to work with PV parks have had to test different financial arrangements and business models such as share-owned
PV parks, power purchase agreements and PV electricity offers to end consumers. The utility companies that have

Task 1 – National Survey Report of PV Power Applications in Sweden
72
built PV parks over 1 MWp are Mälarenergi, Arvika Kraft, Varberg Energi, ETC El, Kalmar Energi, Luleå Energi,
Göteborg Energi, Affärsverken, Vallebygdens Energi and Jämtkraft.
Interest from municipalities and local governments
As can be seen in Figure 4 and Figure 5 there are some municipalities in Sweden that stand out in installed PV in
total and by capita. Important factors for the high local PV diffusion rates are in general peer effects [69] and local
organisations that promote PV. Research has shown that the influence of local initiatives from different stakeholders
has played a major role in the deployment of PV in many of the municipalities with the highest PV penetration in
Sweden [70]. In several cases local electric utilities, often owned by the municipality, have successfully taken an
active role in supporting PV with action such as purchasing the excess electricity of PV adopters, selling PV systems
and dissemination of information. Other local initiatives that have influenced the adoption of PV are seminars and
information meetings arranged by local actors. One example to highlight is the Swedish Energy Agency financed
information campaign for residential PV adoption that occurred in Sweden in 2017, in which 41 % of Sweden’s
municipalities participated and led to a positive effect on PV adoption rates [71].
Some Swedish municipalities and local government have introduced ambitions goal for PV. Examples are:
• In Örebro County, the goal is to produce 150 GWh of PV electricity by 2030, which would correspond to
about 4 percent of the county's electricity use [72].
• The municipality of Uppsala that has set a goal to have approximately 30 MWp of PV by 2020 and about
100 MWp by 2030 [73].
• The municipality of Helsingborg has set an ambition that local production of solar power corresponds to
10 percent of electricity demand in 2035 [74].
• Kristianstad's goal is for the municipal group to produce 2 GWh of solar energy per year in 2020, and 40
GWh per year in the municipality by 2030 [75].
Another activity several municipalities have implemented is the fabrication of so called “sun maps” to help potential
stakeholders in PV to easier assess the potential for their roof. These “sun maps” illustrate in colour scale the
incoming solar radiation on all the roofs in the city, sometimes considering the tilt of the roof and shadowing effects
of nearby buildings or building elements. At the time of writing the sun maps that the author is aware of are; Ale,
Alingsås, Borlänge, Borås, Botkyrka, Danderyd, Ekerö, Eskilstuna, Eslöv, Falkenberg, Falun, Forshaga, Gävle,

Vellinge, Värmdö, Värnamo, Västerås, Ånge, Ängelholm, Örebro, Örnsköldsvik, Östersund and Österåker.
There are 15 regional energy agencies (Energikontoren) in Sweden whose purpose is to promote energy efficiency
and the use of renewable energy at local and regional level. With support from the Swedish Energy Agency
(Energimyndigheten) they coordinate national initiative project with the municipality's energy and climate advisers.
The largest local PV promoting project is probably the association Solar Region Skåne, which started in 2007 as a
collaboration between the municipality of Malmö, the regional energy agency of Skåne (Energikontoret Skåne) and
Lund University. Solar Region Skåne is a network and knowledge centre for solar energy activities in the Skåne
province.

8 HIGHLIGHTS AND PROSPECTS
Highlights
The positive PV market development in Sweden continued in 2019 as the annual market grew with 83 % to a yearly
installed power of 289 MW. This led to Sweden passing the 700 MW threshold as the cumulative installed capacity
at the end of 2019 was 714 MW. The PV system prices continued to decrease with about 2–4 % in 2019 for both
residential and commercial grid connect roof-mounted systems. The price decline seems to have been higher, about
8 %, for centralized ground mounted PV parks.
The major policy change in 2019 that affect the Swedish PV market was the lowering of the support level from 30 %
to 20 % in the direct capital subsidy programme as of May 2019. This policy change might actually have a positive
effect on the market, since a lower support level enables support for larger a PV capacity within the limited
programme budget.On the industry side, basically no module production occurred in Sweden. Some Swedish
companies focusing on new PV technologies or balance of system components continued to develop in a healthy
way, while others were forced to liquidate their business. Furthermore, the Swedish PV industry is becoming
broader as more and more actors with other core businesses, such as utilities and real estate owners, are taking
an increasing interest in the PV technology.
Prospects
In the very short term, the Swedish PV market is facing three major uncertainties. The first one is how the COVID-
19 pandemic and the resulting economic recession will affect the PV market. Due to the restrictions implemented
to slow down the spread of virus, the overall activity in Sweden has gone down, leading to inter alia lower electricity
prices, higher unemployment and less profitability of companies. The lower electricity prices have a negative impact
of the profitability of new and existing PV systems, while higher unemployment and reduced profitability of
companies has a negative impact of the available capital and the willingness to invest this in PV.
The second uncertainty is that the current ordinance of the major subsidy in Sweden, the direct capital subsidy
programme, will end as of the last of December 2020. For private individuals the government has presented a
proposal to replace the direct capital subsidy with a tax reduction for installing green technology [76], which is similar
to the current ROT tax deduction. In this memorandum it is suggested the tax reduction for installation of green
technology is provided with 15 percent of the charged labour and material costs for the installation of solar cells and
with 50 percent of the charged labour and material costs for installation of storage of self-produced electric energy
and installation of charging point for electric vehicles. The suggested tax reduction amount to a maximum of 50,000
SEK per taxation year. Even if the support level is lower than in the current direct capital subsidy programme, this
transition to a tax reduction could be very beneficial for the residential sector as it will decrease the amount of
administration as there will be no need for private homeowners to be granted money, which in some cases has
taken more than a year with the current direct capital subsidy programme. However, it is uncertain what will happen
with the commercial sector. Companies are not allowed to apply for the tax reduction. If no other support scheme
is introduced, this market segment might take a hit as the support level drops from 20 % to zero as of 2021.
Thirdly, an unexpected communication from the Government on June 10, 2020, the government introduced an
application deadline for photovoltaic support as of July 7, 2020. Individuals and companies that were considering
installing solar cells in the fall of 2020 thus had less than a month to make the decision and apply for photovoltaic
support of 20 percent after the communication.
In the medium term, it is expected that the Swedish PV market continues to grow. The introduction of the tax credit
for micro-producers in 2015, the applied (and coming) reforms to reduce the administrative burdens for PV
investors, the launch of an information platform by the Swedish Energy Agency and the increase of activity from
utilities have made the situation quite good for homeowners and small companies to invest in PV. One example of

an up-coming suggested reform that will make it easier for investors in small PV system is the harmonization of the
definition “micro-producer” that is defined different in different laws [55][31]. Another suggested regulatory change
is that property owners should be allowed to build small micro grids that connect different buildings within their
premises [77].
Large centralized PV parks has been a marginal occurrence in Sweden until now. However, this market segment
is believed to grow a lot in the coming years, as it seems to be on the brink of manage without any subsidies.
In the long term, the Swedish PV market is in a good position to grow. In general, there is a growing interest for PV
in Sweden and the public is very positive towards the technology. In October 2016, the Swedish Energy Agency
presented a broad PV strategy for Sweden. This strategy includes a vision that 5 to 10 % of Sweden's total electricity
demand could come from PV in 2040, which would correspond to roughly 7–14 TWh [78]. Furthermore, the goal of
the broad political agreement of The Swedish Energy Commission that Sweden shall have a 100 % renewable
electricity consumption by 2040 [79] forebodes a policy framework in which PV should be able to flourish.
