METHOD AND SYSTEM FOR TESTING WEATHER RESISTANCE OF PHOTOVOLTAIC MODULE

摘要

The present disclosure relates to a method and system for testing weather resistance of a photovoltaic module. The method includes sequential steps of: according to a predetermined appearance inspection standard, performing an appearance defect inspection on the photovoltaic module; testing a light attenuation rate of the photovoltaic module, and when the light attenuation rate is smaller than a predetermined attenuation threshold, under a predetermined test condition, checking an output power of the photovoltaic module; simulating a climate environment, and performing an environmental weather resistance test on the photovoltaic module; according to the appearance inspection standard, performing an appearance defect inspection on the photovoltaic module; testing the light attenuation rate of the photovoltaic module, and when the light attenuation rate is smaller than the attenuation threshold, checking the output power of the photovoltaic module under the predetermined test condition; and ending testing of weather resistance.
