Durability of Photovoltaic Laminated Glass Modules Affected by Temperature-Humidity Cycles

Abstract

Temperature and humidity cycles test of photovoltaic glass modules are carried out by different cycling time. The change of transmittance, interface and strength of photovoltaic glass modules are compared by different experiment time. With the increasing of temperature humidity cycle time of photovoltaic glass modules, the light transmittance of influence is more serious, and stress strength of the longest cycle is weakened 32.84% than one cycle. Therefore, the influence of photovoltaic glass modules under different temperatures and humidity conditions is more serious. So it is very necessary to study durability and safety under temperature and humidity cycles of photovoltaic glass, related to power generation efficiency of the photovoltaic glass modules.
