A kind of processing method of low-power solar photovoltaic module

Abstract

The invention discloses a low-power solar photovoltaic assembly processing method, and relates to the technical field of solar battery assembly processing. The method comprises the steps of scribing abattery piece according to a predetermined route; splitting the battery piece along a scribing route perpendicular to main grid lines according to the predetermined route or part of the predeterminedroute to obtain fragment battery pieces; connecting the fragment battery pieces in series by a conductive material to form battery unit strings, and connecting the battery unit strings in series to form a battery string at the same time; splitting the battery string into target battery strings along a route parallel to the main grid lines; laying the target battery strings on a predetermined plane, bending the conductive material between two adjacent target battery unit strings, and enabling the target battery unit strings to be sequentially arranged and fixed along a direction perpendicularto the main grid lines to obtain a battery array; laying an adhesive film and a sheet material in sequence from inside to outside on two sides of the battery array, and extracting a lead of the battery array; and laminating the battery array, the adhesive films and the sheet materials into a whole by heating and laminating to obtain a laminated member. The method disclosed by the invention reducesthe labor cost required by series welding and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of processing solar cell components, in particular to a processing method for low-power solar photovoltaic components. Background technique [0002] Since solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible supply, the study of solar power generation has become the main direction for the development and utilization of new energy sources, and power generation through solar cells has become a major way for people to use solar energy today. [0003] In conventional solar photovoltaic modules, whether it is a large module used for power generation in a power station or a low-power module used in civilian life, the battery sheets are connected into battery cell strings through conductive materials, and then the battery cell strings are arranged separately. The bus bar welds the battery cells into the whole battery string. The whole process takes up a lot of manpower, and b...

[0003] In conventional solar photovoltaic modules, whether it is a large module used for power generation in a power station or a low-power module used in civilian life, the battery sheets are connected into battery cell strings through conductive materials, and then the battery cell strings are arranged separately. The bus bar welds the battery cells into the whole battery string. The whole process takes up a lot of manpower, and because the bus bar is close to the battery sheet, it is easy to damage the battery sheet during the manual welding process.

Especially for low-power photovoltaic products, it is necessary to scribing and boosting the voltage of the cells, which involves more manual operations and cannot guarantee consistent product performance. If automatic welding is used, the automation requirements for the equipment are very high
