Photovoltaic system with glass fibers

Abstract

A photovoltaic system with glass fibers comprises a solar photovoltaic module frame and a junction box for a photovoltaic panel. A bayonet for mounting a solar cell module is arranged on the inner side of the frame, a night side of the frame is a mounting surface, a mounting cavity is arranged between the mounting surface and the bayonet, at least one vent hole is arranged on a sunward side of the frame and communicated with the mounting cavity, the solar photovoltaic module frame is made of glass fiber materials, the junction box for the photovoltaic panel comprises a junction box body and a box cover, four clamp grooves are arranged on one side of the junction box body, fixture blocks are arranged on the other side of the junction box body, clamp hooks corresponding to the clamp grooves are arranged on the box cover, elastic clamp hooks corresponding to the fixture blocks are arranged on the box cover, and the junction box is made of glass fiber materials.

Description

technical field [0001] The invention belongs to the field of photovoltaic devices, in particular to a photovoltaic system using glass fiber. Background technique [0002] When the solar cell module is in use, it will generate heat due to the irradiation of sunlight, and a certain amount of heat will be generated inside, which will increase the temperature of the battery sheet, resulting in a decrease in photoelectric conversion efficiency. Large-scale photovoltaic power generation systems such as building walls or photovoltaic curtain walls Among them, especially in photovoltaic power generation systems combined with buildings, solar photovoltaic modules are mostly used side by side, and they are closely connected to each other. Due to the aluminum alloy material used in the frame, the installation cavity formed in this way is isolated from the sunny side of the frame. , causing the heat on the back of the solar cell module to not dissipate smoothly, resulting in a continuou...

Problems solved by technology

[0004] The object of the present invention is to provide a photovoltaic system using glass fibers, a solar photovoltaic module frame that can smoothly dissipate the heat on the back of the solar cell module, so that the working efficiency of the solar photovoltaic module remains stable, and glass fiber replaces aluminum alloy to cause The overall cost and weight are reduced, which overcomes the defect that aluminum alloy is a non-ferrous metal and is more vulnerable to the threat of anti-dumping. In addition, the main body and the box cover of the junction box are fixed by using glass fiber materials and combining the slot and hook. It is easy to fix and seal, and at the same time, it is convenient to open the box cover through the elastic hook. The safety, flame retardancy and aging resistance are consistent, and the performance is good. The cost is one-third of that of plastic materials.
