PV modules refer to the smallest and indivisible photovoltaic cell combination device with packaging and internal connection, which can provide DC output alone, and different specifications of solar cell combination cut by solar cells or by laser cutting machine or steel wire cutting machine. compose together.

The composition of photovoltaic modules and the functions of each part

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

2.EVA. It is used to bond and fix the tempered glass and the main body of power generation (such as batteries). 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 In addition to the quality of the EVA itself, the power generation quality of the module is also greatly affected by the lamination process of the module manufacturer. For example, the adhesiveness of the EVA 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, affecting the component life.
