Abstract:
The primary objective is to evaluate the thermal behavior of EVA encapsulant based commercial glass-glass (GG) and glass-polymer backsheet (GB) modules through outdoor accelerated testing at two different weather conditions – Arizona (AZ) and Florida (FL) site. Two sets of module substrates (GG and GB) comprising of four modules each with 4 different thermal insulation thickness have been investigated: no insulation (NI), aluminum tape (Al tape), 0.5-inch thermal insulation, 2-inch thermal insulation (T1, T2, T3 and T4, respectively). Substrate temperatures of the modules were monitored from March 2020 to September 2020 and were analyzed in conjunction with the weather station data obtained from both sites. Non-destructive module level characterization techniques that includes I-V curve tracing, ultraviolet fluorescence (UVF) imaging, electroluminescence (EL) imaging and infrared (IR) were performed on the front side of the modules both before the stress tests (i.e. pre-stress) and after the field accelerated stress tests (i.e. post-stress) to determine the best performing module substrate and to identify the failure modes.
