“…Regarding the technology-dependent degradation, 1% degradation is reported for the crystalline silicon and a-Si modules, 0.6% for the CdTe and 0.5% for the CIGS modules [43]. On average, the degradation rate is in the range 4.5%-6% and even 10% in the case of CdTe [6,[44][45][46].…”

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.

“…Regarding outdoor, change in parameters were observed depending on the location and climatic conditions (Bücher et al, 1997, Gottschalg et al, 2013. Phinikarides et al (2015) carried out an investigation on 12 grid-connected photovoltaic systems in Cyprus centered upon multi-crystalline silicon (multi-c-Si), monocrystalline silicon (mono-c-Si), Heterojunction with Intrinsic Thin layer (HIT), CdTe, CIGS and a-Si. They also observed that both the mono-c-Si and multi-c-Si technologies displayed higher seasonal variations, with greater average standard deviation when compared with thin film technologies (Phinikarides et al, 2015).…”

The photovoltaic (PV) lifetime and the return-on-investment for local PV system installation rely on long-term device performance. Understanding the efficient degradation behavior under a given set of environmental conditions is, therefore, a primary goal for experimental research and economic analysis. The modules were characterized with measurement of their I-V features under similar outdoor condition. Moreover, measurement of different meteorological parameters like humidity and temperature is done from the weather station. The present study aims to measure electrical characteristics (I sc , V oc , P max and FF) in monocrystalline and amorphous silicon modules exposed for 5 years in a sub-oceanique climate in Cologne. The results show the P max of monocrystalline silicone has more degradation (3.41%/year) than the amorphous silicon (1.76%/year).

“…In addition, the undersized inverter affects the seasonality of PV system performance not only from the amplitude but also the seasonal patterns (only in a-Si system). Meanwhile, the seasonal time series decomposition methods (CSD, STL and ARIMA) are superior in the degradation rate calculation with robustness and insensitivity to outliers, as recommended by other authors (Phinikarides et al, 2013;Phinikarides et al, 2015;Ye et al, 2014).…”

“…Among the numerous statistical software involving ARIMA, Bereau, 2016). Due to the monthly PR time series as short as three years, some ARIMA models were unable to converge and therefore, the airline model ARIMA(0, 1, 1)(0, 1, 1) 12 was pre-selected with successful description about the majority of seasonal time series (Phinikarides et al, 2015). Another fundamentally important use of X-13ARIMA-SEATS is to extend the series with forecasts as long as 5 years.…”
