Outdoor solar photovoltaic power plants will inevitably encounter extreme weather conditions. What is the impact on photovoltaic power plants under extreme weather conditions? 1. The influence of extreme temperature Extremely low temperature and extremely high temperature will affect the life spam of the device. Extremely low temperatures can cause ground frost and damage the foundation. Extremely hot weather may damage the output power of the panel. An increase in temperature will cause the surface of the component to overheat, which will result in a sharp drop in the power generation efficiency of the module. According to the surface test results, if the temperature rises by 10°C, the aging rate of photovoltaic modules will double. At the same time, photovoltaic module packaging materials and cables will also be affected by high temperatures that accelerate aging.
