Abstract Current research focuses on the performance degradation of photovoltaic (PV) modules, examining both crystalline silicon (p-Si and m-Si) and thin-film technologies, including a-Si/c-Si, HIT, CdTe and CIGS. These modules were operated outdoors in two distinct climatic zones in the United States (US) over a period of three years. The degradation analysis includes the study of various quantities, such as the decrease in peak power, the reduction in current and voltage, and the variation in the fill factor. The annual degradation rate (DR) of PV modules is obtained by a linear fit of the effective maximum… More >
