Do you know how many steps are required from the production, processing to the delivery of photovoltaic modules?


The first step is monolithic soldering: the cells are welded to the interconnection strips (tinned copper strips) to prepare for the series connection of the cells.


The second step is series welding: the cells are connected in series according to a certain number.


Step 3: Lamination: Continue the circuit connection of the battery strings, and protect the cells with glass, EVA film, and TPT backplate.


Step 4 Lamination: Cells and glass, EVA film, and TPT backsheet are bonded and fused together under certain temperature, pressure, and vacuum conditions.


Step 5 Framing: Cover the glass with an aluminum frame for easy installation at the same time.


Step 6 Cleaning : Ensure the appearance of the components.


Step 7: Electrical performance test: test the insulation performance and power generation power of the module


Finally, it is packed and put into storage.
