Abstract

The invention discloses a frameless FRP half-piece photovoltaic assembly, and the photovoltaic assembly comprises a laminated part and a junction box, and the laminated part sequentially comprises a light-weight high-light-transmission front plate, a front EVA packaging layer, a solar cell module, a rear EVA packaging layer, and an FRP backboard from the top to the bottom. The front EVA packaginglayer and the rear EVA packaging layer are used for bonding the light high-transmittance front plate, the FRP back plate and the solar cell module into a whole, and the junction box is a three-split junction box which is arranged in the middle of the FRP back plate. By means of the mode, the glass cover plate of the half photovoltaic module can be replaced with a light high polymer material, overall weight reduction of the photovoltaic module can be achieved, the surface of the photovoltaic module cannot be damaged due to tiny collision action, and transportation convenience and installation safety of the photovoltaic module are improved.

Description

Technical field[0001]The invention relates to the field of photovoltaic power generation, in particular to a frameless FRP half-cell photovoltaic module and its production process.Background technique[0002]With the development of the times and the advancement of technology, half-cell photovoltaic modules have quickly become the mainstream products of photovoltaic modules due to their low internal consumption and high overall module power. However, half-cell photovoltaic modules take into account the solar energy conversion efficiency and the effect of solar energy during the production process. For the protection of solar cells, highly transparent glass is generally selected as the panel material of photovoltaic modules. Although the use of glass as a panel material has a series of advantages such as good weather resistance, high hardness and good light transmittance, the glass itself is dense and brittle, and it is easy to cause damage due to accidental bumps during installation an...
