Description

Technical Field

[0001] The present application belongs to the field of photovoltaic technology, and specifically relates to a frame and a photovoltaic module. Background Art

[0002] As the core part of the solar power generation system, photovoltaic modules convert solar energy into electrical energy and send it to the battery for storage or to drive the electrical load to work. Photovoltaic modules include laminates and frames, where the laminates include the front plate, the front plate film layer, the battery cell, the back plate film layer and the back plate. The frame is used to fix and support the laminates, and has certain requirements for its strength and impact resistance.

[0003] The front panel of the lightweight photovoltaic module is made of high molecular polymer, with a thickness as low as 4mm and a surface density of up to 4.3kg / mm 2 , usually do not use the frame for packaging. However, photovoltaic modules with tempered glass front panels usually use the frame for packaging.

[0004] Due to the lack of frame structure for support and protection, when lightweight photovoltaic modules are installed on roofs with large spans of color steel tiles / brackets, they will be severely deformed due to outdoor exposure, resulting in dust accumulation on the modules and power generation loss. Since the rigidity of lightweight photovoltaic modules is less than that of photovoltaic modules with tempered glass front panels, the frames suitable for the latter cannot effectively protect and support the former, that is, conventional frames cannot meet the load requirements of lightweight photovoltaic modules. Summary of the invention
