A Novel Method for Investigating Photovoltaic Module Degradation

Effects of UV on power degradation of photovoltaic modules in combined acceleration tests

“…Several cases of PV module degradation caused by single UV exposure have been reported, for example, the delamination at the glass=encapsulant or cell=encapsulant interface, 5,6,9,12) the discoloration of the encapsulant [1][2][3][4]6,[9][10][11]13) and backsheet, [14][15][16] and recently the production of acetic acid in the encapsulant. [17][18][19] However, current standard PV module qualification tests such as IEC 61215 are considered insufficient for the evaluation of UV impact as well as the combined effect of multiple factors on PV modules.…”

Energy performance of different silicon photovoltaic technologies under hot and harsh climate

“…(i) electrical parameters from IeV curves recorded under outdoor or simulated indoor conditions and corrected to STC [21,26], (ii) regression models such as the PVUSA (Photovoltaics for Utility Scale Applications) and Sandia models [27], (iii) normalized ratings such as PR (performance ratio) [4,10,13], (iv) scaled ratings [28,29] of the modules performance in relation to the seasonal variation.…”

Performance Factors of the Photovoltaic System: A Review

“…However, the presence of solar tracker increases the efficiency of PV output power and the dust accumulation effect able to be reduced by 50% at a peak time. The comparison of PV performance under clean and dusty conditions have been evaluated by [18]. The result shows that the maximum power loss for polycrystalline and monocrystalline module is about 18 to 78% respectively while maximum current loss is from 23% to 80% for both types.…”
