The Composition Of Solar Modules Aug 24, 2022

1. Tempered Glass

Its function is to protect the main body of power generation.

2. EVA

It is used to bond and fix the tempered glass and the main body of power generation. 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, thus affecting the light transmittance of the module. Encapsulates the power generation body and the backplane.

3. Solar Cells

The main function is to generate electricity. The mainstream in the power generation market is crystalline silicon solar cells and thin-film solar cells, both of which have their own advantages and disadvantages.

4. Photovoltaic Back Sheet

The back sheet plays a role in protecting the cells, and the backplane must be sealed, insulated, waterproof, and resistant to aging.

5. Aluminum Alloy Frame

Protect the laminate and play a certain sealing and supporting role.

6. Junction Box

It protects the entire power generation system and acts as a current transfer station. If the components are short-circuited, the junction box automatically disconnects the short-circuit battery string to prevent the entire system from being burned out.

7. Silica Gel

It acts as a seal and is used to seal the junction between the component and the aluminum alloy frame, the component and the junction box.
