The whole piece can also be used
But after cutting, it can be assembled into solar panels of any size and shape, which is more versatile
And generally monocrystalline or amorphous The internal resistance of silicon solar cells is relatively large, so it is best to use multiple solar cells in parallel to reduce the internal resistance. However, parallel connection will also increase the dark current on the battery surface and reduce battery efficiency. Therefore, small solar panels can be connected in series and parallel according to the needs of different occasions
