How to choose solar cells before the start of production? #‎Lensun‬ flexible Solar Panel

Step two, test the solar cells on by one by device(red mark on the picture), and take out the faulty solar cell.

With these two steps, we can take out about 3% solar cells which can not produce.

Step two, test the solar cells on by one by device(red mark on the picture), and take out the faulty solar cell.

With these two steps, we can take out about 3% solar cells which can not produce.

The 3% fault is choose from A grade solar cells, if choose B or C grade solar cell, there are much more faulty solar cells which can not produce flexible solar panel.
And some of the factories do not do these two steps, then their cost will be lower.

Our #Lensun solar cell is A grade solar cell. If the solar cell is B grade, then they can not produce flexible solar panel. There will be many hidden cracks solar cells when producing.
