Problems solved by technology

[0002] At present, tempered glass has the largest weight in solar cell components, accounting for more than 90% of the weight in solar cell components, and the weight of solar cell components installed in photovoltaic power stations has reached about 20 kilograms per square meter , the matching photovoltaic support frame also needs a certain structural strength to play the role of supporting solar cell components, resulting in the photovoltaic support frame also accounting for a considerable proportion of the construction cost of the photovoltaic power station, making the construction cost of the photovoltaic power station impossible At the same time, in the photovoltaic power station using sun-facing devices, in order to rotate the solar cell components with a certain weight, it also needs to consume a lot of electricity; Widely, reducing the weight of solar cell components has become an urgent problem to be solved. However, in solar cell components, tempered glass not only plays a role in protecting solar cells, but also undertakes the forming of the entire component together with the aluminum alloy frame, reducing the toughness. The thickness of the glass will affect the shape and performance of solar cell components, making it difficult to reduce the weight of current solar cell components

Embodiment 1

[0015] During production, each component of a lightweight solar cell module with a structural foam board as the substrate is sequentially laid with tempered glass, thermoplastic adhesive film, solar cell strings, thermoplastic adhesive film, back sheet, thermoplastic Adhesive film and structural foam substrate are bonded by lamination; use structural foam substrate larger than tempered glass and back sheet to allow tempered glass and back sheet and solar cells bonded between tempered glass and back sheet The strings are all within the protection range of the structural foam substrate, and the installation holes required for laying are set on the structural foam substrate, and there is no need to install the aluminum alloy frame, which reduces the weight of the solar cell module.

Embodiment 2

[0017] During production, each component of a lightweight solar cell module with a structural foam board as the substrate is sequentially laid with tempered glass, thermoplastic adhesive film, solar cell strings, thermoplastic adhesive film, and backsheet lamination. After molding, a structural foam substrate is then bonded under the backsheet; using the structural foam substrate is larger in size than the tempered glass and the backsheet, allowing the tempered glass and backsheet and the solar cells bonded between the tempered glass and the backsheet The strings are all within the protection range of the structural foam substrate, and the installation holes required for laying are set on the structural foam substrate, and there is no need to install the aluminum alloy frame, which reduces the weight of the solar cell module.

Abstract

The invention relates to a light solar cell module using a structural foam sheet as a substrate, and belongs to the technical field of solar photovoltaic application. The light solar cell module comprises the structural foam substrate, toughened glass, thermoplastic adhesion films, a back plate and solar cell string set pieces, wherein the toughened glass, the first thermoplastic adhesion film, the solar cell string set pieces, the second thermoplastic adhesion film, the back plate, the third thermoplastic adhesion film and the structural foam substrate are laid in sequence from top to bottom and adhere to each other in a laminating mode to form the light solar cell module. According to the light solar cell module using the structural foam sheet as the substrate, the structural foam sheet which is light in weight and high in structural strength, and easy to cut, and has certain rigidity is used as the substrate of the solar cell module, enough high strength and enough high rigidity are provided for forming of the whole solar cell module, the forming effect and the protection effect of the toughened glass and an aluminum alloy frame in the solar cell module are replaced, the purposes that the thickness of the toughened glass is reduced, and the aluminum alloy frame is omitted are achieved, and the weight of the solar cell module is reduced.
