GB/T 46981-2025
ActiveExtended thermal cycling of PV modules—Test procedure
光伏组件扩展热循环 试验程序
Application Summary AI generated
This standard specifies a test procedure for evaluating the durability of photovoltaic (PV) modules under extended thermal cycling conditions, simulating the thermal stress experienced in real-world climates. It is applied in the solar energy industry for qualification testing of PV modules, particularly for products intended for high-temperature or high-thermal-stress environments. The procedure helps manufacturers and certification bodies assess module reliability and resistance to fatigue failure from repeated temperature changes.
