(1) Tempered glass: Its function is to protect the main body of power generation (such as cell), and the selection of light transmission is required:
1. The light transmittance must be high (generally above 91%); 2. Ultra-white tempered treatment.

(2) EVA: Used to bond and fix the tempered glass and the power generation main body (cell). 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 yellow, thus affecting the light transmission of the module. In addition to the quality of the EVA itself, the lamination process of the module manufacturer also has a great influence. Premature aging affects the component life of Solar Panels.
