Abstract: The present disclosure relates to a method and system for testing weather resistance of a photovoltaic module.

Abstract: The disclosure provides a solar photovoltaic module, including a front glass plate, a first packaging adhesive film, a solar cell layer, a second packaging adhesive film, a waterproof layer, a bonding layer and a polymer back plate which are bonded successively. In the solar photovoltaic module provided in the disclosure, the front glass plate with strong rigidity and a flexible polymer back plate with light weight are arranged at two sides of the solar photovoltaic module respectively, thereby reducing the overall weight of the solar photovoltaic module. Meanwhile, the overall rigidity of the solar photovoltaic module can be ensured through the glass back plate, thereby enhancing applicability of the solar photovoltaic module in various products.

Abstract: The present disclosure relates to a method and system for testing mechanical tolerance of a photovoltaic module. The method include 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; performing a mechanical tolerance test on the photovoltaic module; according to the appearance inspection standard, performing an appearance defect inspection on the photovoltaic module; checking the output power of the photovoltaic module under the predetermined test condition; and ending testing of the mechanical tolerance.
