Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and in particular to a photovoltaic double-glass module. Background Art

[0002] At present, when laminating photovoltaic double-glass modules, external aluminum alloy frames are often used to assist. The purpose is to relieve the edge pressure of the module and prevent the peripheral battery strings of the module from sliding inward due to excessive edge pressure, which in turn causes poor spacing between the module strings and leads to module degradation. The use of lamination frames requires a lot of manpower, and the lamination frames will deform after a period of use. Replacing the deformed lamination frames requires costs, and the use of deformed lamination frames can easily cause the lamination frames to press against the back of the module, crushing the module glass and causing the module to be scrapped, thereby causing losses to the photovoltaic module.

[0003] There are many ways to replace laminated frames in the market, such as using corner guards for lamination, but all of them add external support, which has many defects. External support will lead to uneven distribution of component thickness, local thickness is too thin, and it is easy to crush the component glass. Therefore, how to relieve the pressure on the edge of the component and effectively save labor costs and the later maintenance costs of the laminated frame is a technical problem that needs to be solved urgently.
