Junction box, solar cell module and solar cell system using the junction box

Abstract

The invention provides a solar battery assembly, which comprises a substrate and a junction box, wherein the substrate is provided with a front face for receiving radiation, and a back face opposite to the front face; the junction box is arranged on the back face of the substrate, and comprises a junction box body, a pair of fixed arms extending out of both sides of the junction box body, and an accommodating area positioned between the fixed arms; and the fixed arms are provided with buckles which can be matched with an external functional module. Through the setting, a connecting structure among the external functional module, the junction box and the solar battery substrate is simplified, so that the manufacturing procedures and cost of the solar battery assembly are reduced.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a solar battery assembly using photovoltaic effect to generate electricity, a junction box used in the assembly, and a solar battery system using the assembly. 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, one of the main solar energy utilization methods 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 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 photovol...

Problems solved by technology

[0006] However, the installation structure of this inverter is relatively complicated, because not only a lock needs to be provided between the junction box and the inverter, but also a snap-fit ​​method needs to be provided between the solar cell substrate and the inverter.

In addition, through holes of different shapes, such as L-shaped or inverted T-shaped, must be arranged on the solar cell substrate, which undoubtedly further increases the manufacturing process and cost of the solar cell module.
