KingSun 300W High Efficiency Poly Solar PanelsBrief IntrouctionPoly Solar Panel
Polycrystalline solar panels are also made from sillicon.However,instead of using a single crystal of silicon,manufacturers melt many fragments of silicon together to form the wafers for the panel.
Polycrystalline solar panels are also referred to as "multi-crystalline"or many-crystal sillicon.
Because there are many crystals in each cell,there is to less freedom for the electrons to move.As a result,polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.
