“…Degradation processes occur in all types of modules; however, they involve different mechanisms: chemical reactions, mechanical damage, corrosion of metallic parts, encapsulate discoloration or delamination and antireflection coating failure. In general, PV modules degrade faster in hot and dry climates [35][36][37][38] causing losses of even 50% due to the soiling effects [39][40][41]. Temperate climates are advantageous in this context, since precipitation helps to keep modules clean.…”

Due to the observed increase of photovoltaic installations capacity in Poland, the research on the performance of different modules became an important issue from the practical and scientific point of view. This paper is intended to help system planners to choose photovoltaic modules and inverters taking into account the actual operating conditions. The study is devoted to the assessment of four different technologies of photovoltaic modules: polycrystalline silicon (pc-Si), amorphous silicon (a-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe). The data was collected at a solar plant located at high latitude location, in the eastern part of Poland, during the fourth year of the plant operation. The influence of irradiance on the temperature and efficiency of modules was studied. The results show that the efficiency of the pc-Si and CIGS modules decreases with rising temperature; however, the efficiency of the a-Si and CdTe modules is more stable. The impact of changing external conditions on the inverter efficiency as well as array and system losses during various seasons of the year was shown. The inverter efficiency reaches up to 98% in summer and drops as low as 30% in winter. Small average array capture losses of 7.41 (kWh/kWp)/month (0.25 h/day) are observed for the CIGS and 10.4 (kWh/kWp)/month (0.35 h/day) for pc-Si modules. The a-Si and CdTe array losses are higher, up to 2.83 h/day for CdTe in summer. The results indicate high annual energy yields of the pc-Si and CIGS modules, 1130 kWh/kWp and 1140 kWh/kWp, respectively. This research provided new data on pc-Si and especially the performance of the thin film modules and losses in a photovoltaic installation under temperate climate.

The analysis of the degradation of tandem amorphous silicon (a-Si:H) and microcrystalline silicon ( -Si:H): Micromorph thin-film photovoltaic (TFPV) modules and its impact on the output power of a PV array under outdoor long term exposure located in Jaén (Spain) is addressed in this work. Furthermore, the evolution of main solar cell model parameters is evaluated by means of parameters extraction techniques from monitored data of the PV system in real operation of work. The degradation rate and the stabilization period of micromorph TFPV modules, as well as the results of the evolution of each of the solar cell model parameters along the outdoor long-term exposure are analysed in order to gain a better understanding of changes in performance of micromorph TFPV modules and the behaviour of the output power of the PV generator.

“…Одна-ко данные методы требуют установки дополнительного дорогостоящего оборудования: систем измерения эффек-тивности модулей в стандартных условиях, пираномет-ров для измерения мощности солнечного излучения. Достоинством прямого измерения характеристик модуля в стандартных условиях является его точность, однако данные измерения могут приводить к ускорению де-градации характеристик модулей в связи с повышенны-ми механическими нагрузками [6]. Недостатком метода оценки эффективности, основанного на моделировании деградации и отжига оборванных связей, является его сложность и невысокая точность.…”

Разработан метод оценки эффективности работы alpha-Si/mu c-Si солнечных модулей на основе анализа данных мониторинга значения тока и напряжения в точке максимальной мощности и данных измерения температуры поверхности модуля. Приведена методика оценки параметров работы alpha-Si/mu c-Si модулей в ходе эксплуатации после начальной деградации модуля, и произведено сравнение результатов оценки параметров со значениями, измеренными в лаборатории. Ошибка оценки параметров не превысила 3%, для максимальной мощности модуля в стандартных условиях ошибка оценки составила 0.36%. Данная методика может применяться для оценки эффективности модуля и краткосрочного прогнозирования (день, неделя) мощности генерируемой солнечной энергоустановкой в условиях эксплуатации с использованием стандартных средств мониторинга.
