Ensure that the power of cells on a solar panel is the same, and exclude solar cells with abnormal power

The solar cell is cut into small pieces so that the output voltage of the solar moudle meets the design requirements.

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.

Cutting the soldering ribbon and bus bar to the size of the design fits the needs of the solar cell string and laying up.

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 .
