Test purpose:
Before conducting thermal cycling and wet freezing accelerated aging tests, all photovoltaic module samples must be pre exposed to controlled ultraviolet radiation. The core purpose of this preprocessing step is to evaluate the UV resistance of polymer materials and sealant adhesives, which typically degrade, discolor, or delaminate when exposed to UV radiation for extended periods of time.
