SOLAR CELL 150WP ICA POLY
Polycrystalline panels are made up from the silicon off cuts, moulded to form blocks and create a cell made upof several bits of pure crystaland its identifieable by its signature light or dark blue colour, but not uniformly some patches are lighter than others. The differences in appearance come about asesult of the manufacturing process. However, this mis-alignment can help in some circumstances,because the cells work better from light at all angles, in low light, etc.
