Problems solved by technology

The current solar panel uses an aluminum alloy frame, which will hinder the penetration of large-angle oblique light, so that the photoelectric conversion rate will be compromised. In addition, the gap between the frame and the battery needs to be sealed by EVA film. EVA The aging of the film will cause poor sealing, which will reduce the service life of internal components

Abstract

The invention discloses a solar panel and a processing method. The solar panel comprises a body, an AS resin frame and a junction box. The AS resin frame is disposed outside the body. A side of the body is provided with the junction box. The body is composed of tempered Glass, a front EVA film, a PCB, a rear EVA film, a backplane and a crystalline silicon battery sheet. The top of the backplane isconnected with the rear EVA film. The top of the rear EVA film is connected with the PCB. The crystalline silicon battery sheet is uniformly welded to the top of the PCB. The top of the crystalline silicon battery sheet is connected with the front EVA film. The solar panel replaces an aluminum alloy frame with the AS resin frame so that the light inclined at a large angle can also fully irradiatethe surface of the battery, thereby improving the photoelectric conversion rate of the solar panel. Further, sealing is achieved by injection molding the AS resin frame. In cooperation with the frontEVA film and the rear EVA film, a gap between the tempered glass and the PCB can be fully filled, thereby achieving a good sealing effect.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell panel and a processing method. Background technique [0002] A solar panel is a device that directly converts solar radiation into electrical energy through the photoelectric effect by absorbing sunlight. Its main material is silicon. Compared with ordinary batteries, solar panels are an energy-saving and environmentally friendly green product. Solar panels are divided into crystalline silicon cells and thin-film cells. The current solar panel uses an aluminum alloy frame, which will hinder the penetration of large-angle oblique light, so that the photoelectric conversion rate will be compromised. In addition, the gap between the frame and the battery needs to be sealed by EVA film. EVA The aging of the adhesive film will cause poor sealing, which will reduce the service life of internal components. Therefore, it is necessary to design a solar cell panel and a ...
