Solar cell module and solar power generation system

Abstract

The invention relates to a solar cell module. The solar cell module comprise a plurality of solar cell pieces, a back plate for supporting the solar cell pieces and a junction box positioned on the other side of the back plate, wherein the junction box comprises an anode junction box and a cathode junction box; the anode junction box is connected with the anode of the solar cell module; the cathode junction box is connected with the cathode of the solar cell module; and the anode junction box and the cathode junction box are positioned at the positions of opposite angles of the back plate respectively. In the solar cell module, due to the fact that the anode junction box and the cathode junction box positioned on the other side of the back plate are positioned at the positions of opposite angles of the back plate respectively, when at least two solar cell modules are adjacently connected for use, the anode junction box of each solar cell module can be tightly adjacent to the cathode junction box of the adjacent solar cell module, and the anode junction box and the cathode junction box can be directly connected for use, so that the using amount of connecting cables is greatly reduced, the cost can be reduced, the reliability is improved, the generating capacity is improved, and the solar cell module is beneficial for application.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell component and a solar power generation system using the solar cell component. Background technique [0002] As a new energy source, solar energy has the advantages of being inexhaustible, clean and environmentally friendly compared with traditional fossil fuels. At present, the main solar energy utilization method is to convert the received light energy into electrical energy output through solar cell modules, which can be a large-area battery formed by connecting several solar cells (or photovoltaic cells) in series and then packaging them in a square array. components. Among them, the solar cell absorbs light energy, and the accumulation of different charges at both ends of the battery generates a "photovoltaic voltage", which is the "photovoltaic effect". Under the action of the photovoltaic effect, an electromotive force is generated at both ends of the sola...
