... Probably because of their outstanding reliability, crystalline solar modules are the most common ones, boasting a market share of approximately 90%. The best efficiency that can be reached with p-Si modules is about 26.7%, while m-Si PV ones are capable of approximately 22.3% [49][50][51][52][53][54][55][56][57][58]. Nevertheless, the efficiency of the m-Si and p-Si modules that are mostly used today lags behind to a great degree, and remain between 10-18% in the area of the EU [59]. ...
... Concerning the a-Si photovoltaic technology, which is a thin-film-based PV technology, the highest value of efficiency to be reached currently is only 10.5%, which is still about twice as high as the 4 to 6% of the a-Si modules mainly used today. As there is no data currently available about the market share of a-Si technology, one can only make assumptions on the basis of the fact that the total share of all thin-film solar modules constitutes about 10% [49,52,53,[57][58][59][60][61]. ...

With the spread of the use of renewable sources of energy, weather-dependent solar energy is also coming more and more to the fore. The quantity of generated electric power changes proportionally to the intensity of solar radiation. Thus, a cloudy day, for example, greatly reduces the amount of electricity produced from this energy source. In the countries of the European Union solar power plants are obligated to prepare power generation forecasts broken down to 15- or 60-min intervals. The interest of the regionally responsible transmission system operators is to be provided with forecasts with the least possible deviation from the actual figures. This paper examines the Visegrad countries’ intraday photovoltaic forecasts and their deviations from real power generation based on the photovoltaic power capacity monitored by the transmission system operators in each country. The novelty of this study lies in the fact that, in the context of monitored PV capacities in the Visegrad countries, it examines the regulation capacities needed for keeping the forecasts. After comparing the needs for positive and negative regulation, the author made deductions regarding storage possibilities complementing electrochemical regulation, based on the balance. The paper sought answers concerning the technologies required for the balancing of PV power plants in the examined countries. It was established that, as a result of photovoltaic power capacity regulation, among the four Visegrad countries, only the Hungarian transmission system operator has negative required power regulation, which could be utilized in power-to-gas plants. This power could be used to produce approximately 2.1 million Nm3 biomethane with a 98% methane content, which could be used to improve approximately 4 million Nm3 biogas of poor quality by enriching it (minimum 60% methane content), so that it can be utilized. The above process could enhance the viability of 4–6 low-methane agricultural biogas plants in Hungary.
... In the case of unglazed glazing of a photovoltaic, the decrease in electrical efficiency is linear and equal to 0.015 when the temperature was between 25 °C and 34 °C and the solar radiation increased from 100 to 1000 W/m 2 [38]. According, Zsiborács et al. [39], with silicon photovoltaic cells, a decrease of 1 °C in temperature will result in an average increase of 0.27% in efficiency of energy production. ...

Access to electricity and supplying reliable energy are the key elements that support local economic development and contribute to reducing poverty. Moreover, the problem of environmental protection can be considered as a factor of sustainable development. In response to these many challenges, appropriate national and regional policies, as well as mechanisms, have been implemented. In Mali, strong dependence on the importation of oil, growth in demand, and the low rate of electrification have pushed the highest authorities to think of diversified technological solutions like renewable energy for the satisfaction of energy demands, especially photovoltaics, for which the country has significant potential. The hybrid systems used is a compromise, because the emission rate of carbon dioxide emitted by thermal power plants must be reduced and limited to preserve supernatural disasters. For this, hybrid photovoltaic systems coupled to the grid increased, but the management of the production of these photovoltaics poses a lot of problem due to its intermittent status. It is in this context that we conducted an optimization study of a hybrid system photovoltaic connected to the grid. We applied our approach to the most extensive distribution post of Mali capital. For the simulation, we used the modeling and simulation tool named HOMER.

The energy demand of mankind is constantly growing, thus the utilization of various renewable energy sources, which also reduces negative environmental effects, is becoming more and more important. Because of the achievement of climate protection targets, photovoltaic (PV) energy has an increasing role in the global energy mix. This paper presents the technical and economic aspects of different photovoltaic system configurations designed to suit the Hungarian renewable energy regulations. In this study, five alternative PV configurations were examined for systems with a capacity from 50 kW to 500 kW, related to low-and medium-voltage installations. This article also introduces and explains the Hungarian economic PV and Feed-in-Tariff (FiT) regulations, where three different investment alternatives are analyzed with the help of economic indicators. This study could help stakeholders in the market (e.g., the Hungarian industry sector and local governments) understand the possible directions of technical and economic PV development. According to the results, the payback periods in all the studied economic-technical cases were below 10 years. The experimental results show that each investment option may be a good decision from an economic and technical point of view under the Hungarian regulations in force in 2019.

L'objectif principal de cette étude est l'optimisation de la production d'électricité d'une centrale photovoltaïque d'une puissance de 50MWc, située à KITA dans une zone dont le climat est caractérisé par de hautes températures. La connaissance de la température des cellules photovoltaïques (PV) est d'une importance significative pour la prédiction de l'efficacité que le système PV peut atteindre pendant le fonctionnement. Dans cette étude on se focalise sur l'analyse de l'écoulement de convection forcée laminaire autour d'un panneau PV, élément principal d'une centrale photovoltaïque, soumis aux conditions climatiques spécifiques du Mali pour une journée type, c'est-à-dire la température ambiante, l'éclairement ainsi que la vitesse et la direction du vent. Les équations de transport de masse, de quantité de mouvement et de l'énergie sont résolues numériquement en utilisant la méthode des volumes finis. Nos résultats montrent que la prise en compte de l'effet du vent joue un rôle important dans l'estimations de température des cellules photovoltaïques.

This paper examines the thermal properties of free-standing, ground-installed, south-facing crystalline and amorphous silicon photovoltaic modules, the remaining energy and the energy generation of the modules, in ideal and actual summer weather conditions. This work studies the algorithms in other studies used to describe the thermal processes occurring on the surface of photovoltaic modules. Using accurate devices and real, measured data, the deviations and the inaccuracies of theoretical approaches are investigated. The emphasis of the present study is to improve the simulation accuracy of the total emitted long-wave radiation at the module surface and to show the appropriate overall convection coefficient values for ground-mounted south-facing photovoltaic technologies. The innovative aspect of the present paper is an improved model resulting from an improved convective heat transfer and net long-wave radiation calculation. As a result of this research, algorithms describing the energy fluxes were developed. These algorithms have a 1-3% better accuracy of the net long-wave radiation calculations at the module surface. The rate of net energy exchange by convection at the module surface could be improved by 10-12% compared to the previous literature.

The aim of the study is to compare the tilt angle-orientation and dual-axis tracking characteristics of mono-(m-Si), polycrystalline (p-Si), and amorphous silicon (a-Si) modules in the summer of 2017, under real meteorological conditions with simulated data. The most important new element of our study is that, besides a comparison of the three most significant photovoltaic types, the technologies are differentiated by examining specific energy generation using dual-axis tracking and four different orientations at 5-degree intervals compared to simulated values, near to the summer solstice. For these types of measurements, as far as we are aware, there is no previous reliable, well-supported, comparative data. The simulated data show less accurate results, proving the importance of real data. Based on simulated data, the tilt angle and orientation showed about 10% favorable values compared to reality. Knowing our results can make it easier to plan investment, and estimate the investment and operational costs and their return on crystalline and amorphous silicon solar modules, for both sun-tracking and fixed systems with various orientations and tilt angles.
