Problems solved by technology

Polycrystalline silicon cells in the industry have several standard sizes, and each cell is usually connected in series in a common way to form a battery string. The first and last ends of the battery string are connected to the junction box through bus bars, but In this single series method, the actual power output of the components is difficult to increase, and there is no effective means to reduce the loss on the connection line
In addition, the individual differences (such as efficiency consistency and matching) between the cells in the battery string will also easily affect the overall efficiency of the cell assembly.

Abstract

Disclosed in the invention is a solar photovoltaic assembly comprising a battery panel and two two-into-one junction boxes. A piece of tempered glass, a high-permeability EVA board, a battery string,a high-cut EVA and a back board are arranged from top to bottom in a lamination layer sequence; and the two two-into-one junction boxes are arranged at the upper and lower opposite angles of the backboard.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a special-type 5×10 solar photovoltaic module for generating electricity by photovoltaic effect. Background technique [0002] As a photoelectric conversion element, solar cells have received more and more attention and research as a pollution-free energy source because of their safety, ease of disposal, and non-pollution. Since the voltage of solar single cells is relatively low, in order to meet the needs of end users, it is necessary to connect single cells in series to form solar modules. The structure of solar modules is generally in the form of a rectangular array, which is composed of multiple battery strings connected in series. Generally, the number of battery strings is an even number. Two strings are connected in parallel with one diode, and the width of the module is basically 992mm. However, this kind of solar module has strong limitations in installation. Some...
