Frame profile of solar photovoltaic module

Abstract

The invention discloses a frame profile of a solar photovoltaic module. The frame profile comprises an upper frame body and a lower frame body, wherein the upper frame body and the lower frame body are fixedly connected by a welding process, the upper part of the upper frame body is of a clamping groove structure, the lower part of the upper frame body is of a support plate structure, the lower frame body is made of an L-shaped plate material, a hollow cavity is formed by the support plate structure of the upper frame body and the lower frame body, and a through hole structure is formed in an upper panel of the clamping groove structure in the length direction. The frame profile of the solar photovoltaic module, disclosed by the invention, has the advantages that the frame profile is reasonable in structural design, the mounting and use properties are stable, and the through hole structure in the surface of the clamping groove of the upper frame body can effectively increase the light intercepting area of the solar cell module and ensure the photoelectric conversion efficiency; meanwhile, through the clamping groove structure, the mass and the using amount of the frame profile are effectively reduced, and the purpose of controlling the cost is achieved.

Description

technical field [0001] The invention relates to a frame profile of a solar photovoltaic module, in particular to a frame profile of a solar photovoltaic module that can improve the photoelectric conversion efficiency of a solar cell, has stable installation performance, and saves materials, and belongs to the technical field of solar photovoltaic modules. Background technique [0002] As one of the emerging energy sources, solar energy has been applied all over the world and is favored by people because of its characteristics of no pollution and low cost. With the widespread use of solar energy, the solar photovoltaic industry is gradually becoming a new sunrise industry. Solar photovoltaic modules usually include solar cell components and frames. Solar cell components are generally composed of tempered glass, EVA layer, solar cells, EVA layer and back sheet, which are combined by a laminator; while frames are mostly made of aluminum alloy, aluminum The quality frame is fix...

AI Technical Summary

Problems solved by technology

Among them, the single-arm structure is light in weight and saves consumables, but the supporting effect is average, while the preparation process of the double-arm structure is relatively complicated, the amount of consumables is large, the quality of the card slot is large, and the upper panel will block the solar cells, which will affect the solar cells to a certain extent. The effective light-receiving area of ​​the module reduces its photoelectric conversion efficiency
