Abstract

The invention relates to the technical field of solar photovoltaic modules and discloses a solar photovoltaic module, which includes a backplane, and further includes a second adhesive film layer, aninsulating layer, an EVA layer, a solar cell layer, a water blocking layer, a first adhesive film layer, a solar panel and a thin coating; the upper surface of the backplane is attached to the insulating layer through the second adhesive film layer; the EVA layer is attached to the upper surface of the insulating layer; the solar cell layer is attached to the upper surface of the EVA layer; and the water blocking layer is attached to the upper surface of the solar cell layer. The solar photovoltaic module is provided with the solar panel instead of upper glass so as to be improved in overall weight without deteriorating the effect. By applying the thin coating to the solar panel, the solar panel has good heat insulation and thermal insulation effects. By using the water blocking layer, thedevice has a light weight and a good waterproof effect, thereby increasing the efficiency and the service life of the solar cell layer in the device.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic components, in particular to a solar photovoltaic component. Background technique [0002] With the rapid development of solar power generation technology, solar power generation technology has been used in more and more products, and in order to ensure that solar photovoltaic modules have a long service life in various products, it is particularly important for the packaging of solar cell chips. Most solar photovoltaic modules use double-layer glass as the main packaging material, that is, a glass plate is arranged twice before and after the solar cell chip to make the photovoltaic module have higher rigidity. However, due to the heavy weight of the double-layer glass, it will cause The overall weight of solar photovoltaic modules is relatively large, which is not suitable for some products with weak carrying capacity, and solar photovoltaic modules are generally installed in the open ...
