Adhesive-free packaged photovoltaic module

Abstract

The invention discloses an adhesive-free packaged photovoltaic module. The photovoltaic module comprises a lamination part and a frame body; a hydrophobic film layer is arranged on the edge and side surfaces of the lamination part; the hydrophobic film layer is formed by coating the surface of fiber net cloth with a mixed liquid of ethyl orthosilicate and methyltriethoxysilane; the frame body comprise side plates, backup plates, calendering sheets, supporting plates and seat plates, wherein one ends of the backup plates are connected with the side plates in sequence at intervals in a cantilever manner while bumps are arranged at the other ends of the backup plates; pressing heads are arranged at the other ends of the calendering sheets at intervals; groove openings are formed between the calendering sheets and the supporting plates; support plates are arranged between the supporting plates and the seat plates; and wedge-shaped blocks which enable the cantilever ends of the calendering sheets to be bent downwardly are arranged between the calendering sheets and the backup plates at intervals. Sealing connection between a guiding-pressing part and the frame body can be realized without needing adhesive or sealing strips in packaging, so that the problem of sealing failure in manual adhesive coating or sealing strip pressing and mounting can be avoided, so that seal packaging can be ensured effectively, the packaging process is simplified, material and man-hour cost can be saved, and power generation efficiency is improved.

Description

technical field [0001] The invention relates to a solar power generation system, in particular to a photovoltaic module formed without glue sealing. Background technique [0002] Solar energy is a clean and renewable clean energy, so it has been paid more and more attention by the society and favored by people, and plays an important role in social development and people's life and work. Therefore, the use of solar power to generate electricity has been widely used in municipal, household, office, transportation and other occasions. Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, and send the electrical energy to the storage battery for storage, or to drive the load to work. Photovoltaic modules can be laid on the top of various types of buildings to receive sunlight and generate electricity ...

AI Technical Summary

Problems solved by technology

In the prior art, the packaging and sealing of the cell laminates in the photovoltaic module and the frame made of profiles is mainly sealed with glue, and there are also seals with sealing strips. This glue seal has the following problems: the frame It is difficult to apply the glue (glass glue) around it evenly and in the correct position, so after a period of time, the glue is easily aged and degummed in the air, and the package seal fails, which not only affects the power generation efficiency, but also increases the cost of power generation

The use of sealing strips seals firstly that the sealing strips need to be manually assembled, and the assembly volume is large and troublesome, which affects the installation efficiency and increases the cost. Second, the manual assembly operation is careless, which will cause local water seepage
