When the existing solar photovoltaic panel is installed, the photovoltaic panel is installed in a rectangular frame firstly, and then the photovoltaic panel is installed on a solar bracket through a connecting plate on the frame. The frame of the photovoltaic panel is generally formed by splicing four sections and comprises two symmetrical long frames and two short frames, corner codes are inserted into the inner cavities of splicing nodes of the four sections, four pits distributed in a rectangular mode are punched at the end splicing points of the four frames, the corner code locking assembly is realized by utilizing anchor points formed by protruding parts at the bottoms of the pits and saw teeth on the corner codes to be meshed, and the connection of adjacent section frames is completed; in order to meet the waterproof isolation requirements of four sides of a photovoltaic panel, sealant is required to be smeared at the panel clamping part of the frame, when the panel is installed in the frame clamping part, redundant sealant is extruded out of the top surface and the bottom surface of the panel, extruded sealant is reserved in the sealant containing cavity of the clamping part, the sealing effect is enhanced, the sealant extruded out of the frame in the subsequent cleaning process can be avoided, and the operation flow is simplified.
At present, according to the installation direction of a rectangular panel, only a long frame or a short frame of a frame is generally connected with a bracket, namely, only two frames at opposite positions of four frames of the frame are connected with the bracket through connecting plates, and the sections of long frames and short frames of the existing frames are consistent, and all the sections of the long frames and short frames of the existing frames comprise connecting mounting plates, so that the overall weight of a panel assembly is increased, and the manufacturing cost of an aluminum frame is increased; the bottom of the clamping part of the traditional frame is not provided with a corresponding glue containing cavity, so that redundant sealant is extruded out of the bottom of the panel, the subsequent cleaning work is required to be added to the double-sided power generation panel, the sealant layer on the bottom surface of the panel is thin, and the tightness is poor; when the pit anchor points are punched and meshed at the splicing points of the end parts of the frames, punching cracks are easy to generate, so that the section is scrapped, the manufacturing rate is lower, and the production cost is higher.
The Chinese patent application document CN108809237A discloses a novel asymmetric frame for a solar photovoltaic module, and the asymmetric frame is adopted, so that the overall weight of the module is reduced, the manufacturing cost of the frame is reduced, but the frame connecting points are required to be cut for multiple times in different directions, and the complexity of the cutting process is improved; the bottom of the frame clamping part is not provided with a glue containing cavity, so that the sealing effect at the bottom surface of the edge of the panel is poor, and if the panel with double-sided power generation is used, the residual glue at the bottom surface is required to be cleaned;
therefore, there is a need for a solar cell frame that has good sealing properties against the upper and lower surfaces of the panel, is lightweight, has high yield, and is inexpensive.
