The LEEE-TISO (Laboratory of Energy, Ecology and Economy Solar-Ticino), test center of photovoltaic modules in Switzerland, stated that the power degradation rate of crystalline silicon PV modules could go from 0.7% to 9.8% during the first exposure year and 0.7% to 4.9% during the second one (LEEE, 2008).
Temperature, humidity and UV radiation are the main factors of silicon PV module degradation. Modeling of PV module degradation is still poorly studied in literature. Accelerated tests are an alternative for investigating PV module degradation. PV modules are often considered to be the most reliable component of a photovoltaic system.
After years of improvement in photovoltaic (PV) module performance, including the reduction of power degradation rates toward a mean of −0.5%·year −1 to −0.6%·year −1 for crystalline silicon (c-Si) technology, 1 there are new pieces of evidence that the degradation rates for many c-Si modules are now increasing.
Degradation to the module power requires an interaction causingcell-level defects. Degradation of silicon solar cells is dominated by four modes: potential-induced, light--induced, wafer cracking, and metal corrosion. These modes affect the cells in different ways and may range from almost no loss of power to complete loss of power. 4.1.
Accordingly, research must more and more focus on photovoltaic modules degradation. This paper presents a review of different types of degradation found in literature in recent years. Thus, according to literature, corrosion and discoloration of PV modules encapsulant are predominant degradation modes.
