5-10MW Annual Semi-Auto Solar Panel Production Line

Many customers want to open solar panel making plant, but they don’t know the manufacturing process and how to configure solar panel manufacturing equipment so the idea has never been realized.

1. Factory Layout Drawing

2. Mainly manufacturing process

Step 1: Test solar cell efficiency: make sure the same power cell to be used in one solar panel;

Step 2: Cut complete solar cell into small pieces;

Step 3: Welding solar cell: welding solar cell to string solar cell;

Step 4: Cutting EVA/TPT: according to the solar panel size to cut the EVA and TPT in the designed size;

Step 5: Lay up: achieve solar string automatic laying on glass EVA, and transporting module to the next process;

Step 6: Visual inspection: check the dirty for the Raw materials;

Step 7: Defect check: uses the EL tester machine to identifying micro-cracks, broken   finger wires, and other invisible defects in solar modules;

Step 8: Lamination: after EL tester checking the defects,  use solar panel Laminate the raw material into solar panel;

Step 9: Trimming: when the Solar panel get cooling after coming out from laminator,  It need Cutting the edges,  we call Trimming;

Step 10: Glue: use sealant to glue up on aluminum frame;

Step 11: Framing: use the framing machine to install the aluminum frame;

Step 12: Glue: fill the sealant to aluminum alloy after framing;

Step 13: Install junction box: glue the junction box and install it on the solar panel;

Step 14: IV Test: use solar simulator to test the finished solar panel Electrical performance test like power, current etc and record;

Step 15: Test the panel withstand voltage insulation;

Step 16: Defect check: uses the EL tester machine to identifying micro-cracks, broken finger wires and other invisible defects of finished solar modules;

Step 17: Label;

Step 18: Clean the surface and package.
