Solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", solar panel but the production cost is so high that It has certain limitations in its widespread use. Compared with ordinary batteries and rechargeable batteries, solar panel solar batteries are more energy-saving and environmentally friendly green products.
The role of toughened glass is to protect the main body of power generation (such as cells), and the selection of light transmission is required. The light transmission must be high (generally above 91%);solar panel ultra-white toughened treatment. EVA is used to bond and fix the tempered glass and the main body of power generation (such as battery). The quality of transparent EVA material directly affects the life of the module. EVA exposed to the air is easy to age and yellow, solar panel which affects the light transmittance of the module. In addition to the quality of the EVA itself, solar panel the lamination process of the module manufacturer also has a great impact on the power generation quality of the module. For example, solar panel the EVA glue connection is not up to standard, solar panel and the bonding strength of EVA and tempered glass and backplane is not enough, solar panel which will cause EVA to age prematurely. Affect component life.
