Cutting the solar cells and the positive and negative poles of the solar cell are connected in series with the soldering ribbon, and arranged in a fixed manner according to the design.

EVA film and Back sheet are cut to the designed size, and holes can be punched at the designed size to facilitate the extraction of Bus bar.

Use the manipulator to arrange the Tabbing cell stringer on the glass of EVA film according to the designed size .

After Laying up, check the inside of the battery for flaws such as cracks and welding to prevent Laminating from being unable to correct them.

After laying up, all the materials enter the Laminator, and under the condition of high temperature and vacuum, the Solar cell is solidified between the backplane and the glass or panel film by EVA, so as to improve the service life of the solar cell. 

Cut EVA and backhseet that spill out of the glass edges due to laminating, leaving the sides smooth.

Silicon gel is evenly coated in the grooves of the aluminum framer to act as a seal and waterproof .

The four aluminum alloy frames are pressed on the glass to make the solar panel sealed and waterproof, and also to strengthen the rigidity of the solar panel .

Test the maximum power of solar panel and other parameters
