Description

A photovoltaic module with a frame structure

technical field

The utility model relates to a solar photovoltaic assembly, in particular to a photovoltaic assembly with a frame structure. the

Background technique

Solar photovoltaic modules are products that connect multiple single solar cells in series and parallel according to needs, and package them with tempered glass, EVA film, backplane, aluminum alloy frame and other materials through a special production process. the

When photovoltaic modules are combined with buildings, such as installed on the roof, not only must meet the performance requirements, but also consider the coordination of appearance and color. Conventional components generally use silver-white aluminum alloy frames and white backplanes. The color is single and does not match well with dark roof tiles. CN202004022U discloses a black solar cell module, which uses a black frame and a black backplane to meet the aesthetic requirements, but because the black backplane absorbs heat, the power of the module will drop, and such a black module is only suitable for cold regions. the
