ABSTRACT The recent years have seen a strong rise in policies aiming to increase the diffusion of clean energy technologies. While there is general agreement that such deployment policies have been very effective in bringing technologies to the market, it is less understood how these policies affect technological innovation. To shed more light on this important question, we conducted comparative case studies with a global sample of 9 firms producing solar photovoltaic (PV) modules, complemented by in-depth interviews with 16 leading PV industry experts. We propose that, on the one hand, policy-induced market growth serves as an important catalyst for innovative activity as it raises the absolute level of firm investments in technological exploration. On the other hand, however, deployment policies create an incentive for firms pursuing more mature technologies to shift their balance between exploitation and exploration toward exploitation. Firms focusing on less mature technologies cannot tap the potentials of exploitative learning to the same extent as those with more mature technologies. Therefore, stimulating strong market growth may raise the barrier to market entry for less mature technologies. We conclude that, when designing deployment policies, great care should be taken to avoid adverse effects on technological diversity and a premature lock-in into more established technologies.

    ABSTRACT: Research has identified several reasons why fleet managers are good candidates to be electric vehicle (EV) early adopters such as their intense usage and high automobile purchase rates. This expectation is supported by a recent study which found that to 2013, governments and private companies were responsible for a majority of global EV purchases. Using content analysis of fleet manager interviews and pilot project reports, this study investigated 14 US and Dutch organizations that adopted EVs from 2010 to 2013 to determine which factors influenced their purchase decisions. In addition, it also analyzed the reasons why these same firms did or did not expand their EV fleets. Fleet managers identified testing new technologies as being the overarching driver of their initial adoption of EVs. Organizations also noted several influential but secondary factors including lowering their environmental impact, government grants, and improving the organization’s public image. For organizations that decided to expand their EV fleets, the primary motivating rationales were firm-specific, including pursuing first-mover advantage, specialized operational capabilities, or a compelling business model.

    ABSTRACT: Renewable energies have a key role in defining an energy policy based on security, independence, and sustainability. The Italian market is characterised by the absence of support mechanisms for photovoltaic sources for electricity and by a high level of maturity in the energy market. Consequently, this paper contributes to, and advances, the debate concerning self-consumption that can support the economic sustainability of photovoltaic facilities. We constructed a database to conduct an analysis. A survey was conducted among 750 companies operating in various stages of the industry supply chain. The survey collected data related to industry turnover, profitability levels, profitability margins of the business areas and employee numbers. The economic feasibility of photovoltaic investment is evaluated for systems of varying sizes (3 kW, 20 kW, 200 kW, 400 kW, and 1 MW) located in two areas of the country to account for different levels of insolation (northern and southern regions). The indicators used are net present value (NPV) and discounted payback time (DPBT). A subsequent sensitivity and scenario analysis is conducted according to the share of self-consumption, investment costs, and financial structure to examine 210 case studies.

    ABSTRACT: Battery storage is generally considered an effective means for reducing the intermittency of electricity generated by solar photovoltaic (PV) systems. However, currently it remains unclear when and under which conditions battery storage can be profitably operated in residential PV systems without policy support. Based on a review of previous studies that have examined the economics of integrated PV-battery systems, in this paper we devise a simulation model that investigates the economic viability of battery storage for residential PV in Germany under eight different electricity price scenarios from 2013 to 2022. In contrast to previous forward-looking studies, we assume that no premium is paid for solar photovoltaic power and/or self-consumed electricity. Additionally, we run the model with a large number of different PV and storage capacities to determine the economically optimal configuration in terms of system size. We find that already in 2013 investments in storage solutions were economically viable for small PV systems. Given the assumptions of our model, the optimal size of both residential PV systems and battery storage rises significantly in the future. Higher electricity retail prices, lower electricity wholesale prices or limited access to the electricity wholesale market add to the profitability of storage. We conclude that additional policy incentives to foster investments in battery storage for residential PV in Germany will only be necessary in the short run. At the same time, the impending profitability of integrated PV-storage systems is likely to further spur the ongoing trend toward distributed electricity generation with major implications for the electricity sector.
