Test Background
Photovoltaic glass, encapsulation film, and backsheet are the outer protective materials of the module, and their durability is related to the long-term reliability of the photovoltaic module system. Unqualified packaging materials are prone to serious failures such as significant power attenuation, yellowing and cracking of the backplane as time goes by when used outdoors, which will have a serious impact on the return on investment of the power station.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various photovoltaic products and provides professional accelerated aging testing services for photovoltaic module packaging materials.
Scope of tests
is suitable for glass, encapsulating film and backsheet of photovoltaic modules.
Test method
1. Sample pretreatment
