SP series panels are high efficiency monocrystalline cells (the highest available
on the market). The electric contacts create a thick pattern resembling two interpenetrating combs on the
rear of the cell, this guarantees an optimal management of micro fractures, without power loss. Back-
contact cells are also the best choice when it comes to efficiency in low light and sensitivity at higher
temperatures. In fact the temperature coefficient is 25% lower than the other cristalline cells.
