Reduction in performance of WINAICO modules of less than 1 %
Creglingen, 07.08.2012 – TÜV Rheinland has tested WINAICO’s WSP photovoltaic module series of Win Win Precision Technology Co., Ltd. from Taiwan with excellent result. Conventional solar systems have inherently differences in voltage between the system framework and solar cells. The differences can lead to unwanted leakage currents which successively corrode the polymers of the foils within the laminate during the life cycle. This can reduce the performance of the cells and cause a loss of yield. This effect is called potential-induced degradation (PID).
