Solar Panel Production Process
Solar Cell Sorting
1. Appearance:Whether there are lobes, missing corners, broken grid, etc.;
2. Color: Classification of batteries with similar colors
Solar Cell Welding
Weld the welding strip and the main grid line of the battery piece together;
Weld the front battery of the battery piece to the back electrode of the other battery piece to form a battery string
Assembling
1. Tempered Glass
2. EVA (buffer, seismic, heat insulation, moisture-proof)
3. Solar Cell String
4. Backplane (insulation, water resistance, aging resistance)
4 samples are laminated together
Middle Test
Detect whether there are hidden cracks, black chips, dark chips, Broken grid, broken plate, low efficiency plate, over – cutting, positive and negative electrode connection and other problems
Lamination
Vacuum, heat, melt EVA,
Glue the battery, glass, and back plate together
Packaging and Shipment
Shipping by container
