Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electrical energy through photoelectric or photochemical effects. Due to its unlimited and energy-saving properties, it has now replaced fossil energy and become the choice of more and more countries.
The first step in solar panel manufacturing is to prepare raw materials, including solar cells, EVA, glass, backplane, etc. The quality and performance of these raw materials directly affect the performance and quality of solar panels.
The production of solar panel components mainly includes the following steps:
1. Sorting solar cells and placing them in different
2. Cutting solar cells for standby
3. Series-parallel solar cells: Put the solar cells in the string welding machine and connect them in a certain series-parallel manner to obtain the required voltage and current.
4. Laying EVA: Lay EVA on and below the solar cells to play a role in bonding, sealing and insulation.
5. Lamination: Place the glass, solar cells, EVA,and the backplane into solar panel laminator and then lamiantion them to protect the solar cells and improve their reliability.
After that, the solar panels will be tested and graded, classified according to different levels, and sold out of the factory
