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.
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
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
Vacuum, heat, melt EVA,
Glue the battery, glass, and back plate together
Sunway’s Nantong production base currently has four production lines, three of which are automated and one is a manual assembly line, including one automatic scribing machine, four string welders, one stacking welder, four laminators, and three EL inspection channels, which are mainly used to produce cells and modules. Sunway is continuously developing and innovating products to meet the needs of more types of PV module production.
