AI Technical Summary

Technical Problem

In the existing frame photovoltaic modules, a gray-abundant band is easily formed on the edge of the A-side of the laminate, blocking the battery cell from receiving light and affecting the power generation efficiency of the photovoltaic module.

Method used

A frame is designed, including a first side plate, a second side plate and a support structure. Through the installation groove and convex structure, the upper surface of the laminate is fully exposed, reducing dust accumulation problems, and improving bonding reliability through filling of the adhesive layer.

Benefits of technology

It effectively avoids the problem of dust accumulation on the upper surface of the laminate, improves the power generation efficiency of the photovoltaic module, and enhances the connection firmness between the laminate and the frame.

Abstract

The utility model provides a frame and a photovoltaic module. The frame comprises a first side plate, a second side plate and a supporting structure. One end of the first side plate is provided with a first protrusion, one end of the second side plate is connected to the other end of the first side plate, and the other end of the second side plate is provided with a second protrusion. And a mounting groove is formed among the first convex part, the first side plate, the second side plate and the second convex part. The supporting structure is connected to the side, deviating from the mounting groove, of the first side plate. The first side plate is also provided with at least one third convex part, and / or the second side plate is also provided with at least one fourth convex part; and the distance between the convex parts is greater than or equal to 0.8 mm. The contact area between the mounting groove and the glue can be increased through the arrangement of the third convex part and / or the fourth convex part, the space between the adjacent convex parts can be fully filled with the glue by limiting the distance parameter between the convex parts, gaps are reduced, and the connection firmness of the laminated piece and the frame is guaranteed.
