EVA is used to bond and fix tempered glass and power generation main body (such as battery sheet)

The quality of the transparent EVA material directly affects the life of the module. The EVA exposed to the air is easy to age and turn yellow, which affects the light transmittance of the module, thereby affecting the power generation quality of the module. In addition to the quality of the EVA itself, the lamination of the module manufacturer The impact of the process is also very large. For example, the viscosity of the EVA adhesive is not up to standard, and the bonding strength of the EVA to the tempered glass and the backplane is not enough, which will cause the EVA to age prematurely and affect the life of the components.
