Photovoltaic module

Abstract

The invention discloses a photovoltaic module which comprises a photovoltaic baseplate and a plurality of photovoltaic batteries formed on the photovoltaic baseplate, wherein the plurality of photovoltaic batteries are electrically and mutually connected in series. The plurality of photovoltaic batteries electrically and mutually connected in series are defined as several battery packs, a plurality of connecting boxes are installed on the photovoltaic baseplate, a bypass protection device is arranged inside each connecting box, and each connecting box and the corresponding battery pack are electrically connected in parallel. The connecting boxes on two sides of the photovoltaic baseplate are respectively provided with an outgoing line, and the connecting boxes with the outgoing lines control the plurality of electrically and mutually connected photovoltaic batteries. The photovoltaic module can simplify the cable arrangement of the bus bar inside the photovoltaic module, and is stable in working.

Description

Technical field [0001] The invention relates to the technical field of solar photovoltaic applications, and in particular to a photovoltaic module with a junction box. Background technique [0002] With the increasing depletion of global energy resources, the pace of mankind's search for new alternative energy sources is also accelerating. Solar energy is a renewable resource. Converting solar energy into electrical energy can not only save energy, alleviate the shortage of power supply, but also reduce environmental pollution. Therefore, solar photovoltaic technology has attracted more and more public attention and favor. Photovoltaic cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium copper selenide or other materials, so as to use the photovoltaic effect to convert light energy into electrical energy. At present, photovoltaic modules composed of multiple photovoltaic cell units are put into use in large quantities. Fo...

AI Technical Summary

Problems solved by technology

This connection method of one photovoltaic module and one junction box makes the internal circuit of the photovoltaic module 9 partially overlap with the external circuit, and leads to a longer lead wire drawn from the junction box 92, thereby wasting materials and causing line loss. Cause the output power of photovoltaic module 9 to drop, there is room for optimization

In addition, this connection method causes the head bus bars 93, 94, 95 to be turned over, and the stacking operation is complicated, which easily causes debris
