Photovoltaic module laying method and photovoltaic module

Abstract

The invention provides a photovoltaic module laying method and a photovoltaic module, and belongs to the technical field of photovoltaic module preparation, and the photovoltaic module laying method comprises the following steps: respectively cutting a first cutting seam and a second cutting seam which are parallel to each other at two sides of a first EVA adhesive film; laying the first EVA adhesive film and a plurality of battery strings on the photovoltaic glass, so that the battery strings are perpendicular to the first cutting seam and the second cutting seam, and enabling welding stripsat the two ends of the battery strings to sequentially penetrate through the first cutting seam and the second cutting seam respectively; connecting the welding strips with the bus bar; and sequentially laying the second EVA adhesive film and a back plate. According to the photovoltaic module laying method, the first cutting seam and the second cutting seam are cut in the first EVA adhesive film,the welding strips of the battery strings penetrate through the first cutting seam and the second cutting seam to be connected with the bus bar, it is guaranteed that the positions of the battery strings is fixed, and the battery strings are prevented from deviating in the follow-up laminating process; and the production cost is reduced, the working efficiency and the quality of the photovoltaic module are improved, and the service life of the photovoltaic module is prolonged.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic module preparation, and more specifically relates to a photovoltaic module laying method and the photovoltaic module. Background technique [0002] Photovoltaic glass is a kind of special glass that is laminated into solar cells, can use solar radiation to generate electricity, and has related current lead-out devices and cables; photovoltaic glass is ultra-clear glass, also known as colorless glass, highly transparent glass, and low-iron glass. It has high light transmittance and good physical properties. [0003] The laying process of photovoltaic modules is a key link in the production of modules. The main process is to first lift the photovoltaic glass to the feeding table of the laying machine, and lay EVA (EVA is the abbreviation of Ethylene Vinyl Vinyl Acetate, which is a A thermosetting and viscous adhesive film, used to be placed in the middle of the laminated glass), to ensure that...
