Lamination process of photovoltaic hollow glass assembly

Abstract

The invention discloses a lamination process of a photovoltaic hollow glass assembly, which comprises the following steps of: arranging the back surfaces of battery strings upwards, and leading out reserved bus bars at the positions of slots; laying a layer of packaging structure on the back surface of the battery pieces which are arranged in series; covering the back photovoltaic glass on the packaging structure on the battery piece; overturning the front photovoltaic glass and the back photovoltaic glass to enable the front surface of the battery piece to face upwards, separating the leading-out line of the bus bar, and fixing the leading-out line by attaching to the front photovoltaic glass; carrying out lamination on the prepared photovoltaic module; and after the lamination is finished and cooling is carried out, aligning the junction box with the outgoing line of the bus bar for installation, and fixedly welding the leading-out line of the bus bar with the terminal of the junction box. The lamination process flow of the photovoltaic hollow glass assembly is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaics, and in particular relates to a lamination process of photovoltaic hollow glass components. Background technique [0002] The solar photovoltaic hollow module is a new green product that organically combines photovoltaic power generation modules with hollow glass. It is mainly composed of solar photovoltaic modules, spacers, sealants and safety glass. Because the traditional solar photovoltaic modules generally have a junction box attached to the back, and the cavity behind the hollow module and the glass will seal the junction box in the middle cavity, resulting in no electrical connection between the hollow modules. Afterwards, hollow components widely used the junction box to exit the side of the component to solve this problem. However, the side exit of the junction box will cause the junction box to exceed the size of the component, and the junction box is prone to collision and ...

AI Technical Summary

Problems solved by technology

Because the traditional solar photovoltaic modules usually paste the junction box on the back, and the cavity behind the hollow module and the glass will seal the junction box in the middle cavity, so that the electrical connection between the hollow modules cannot be carried out.

Afterwards, hollow components widely used the junction box to exit the side of the component to solve this problem. However, the side exit of the junction box will cause the junction box to exceed the size of the component, and the junction box is prone to collision and displacement during manufacturing, storage or transportation. Position and other issues, and the problem of protruding junction boxes often needs to be considered when arranging hollow components
