Product Description

70w mono solar panels

 

Mono-crystalline solar cells are cut from a chunk of silicon that has been grown from a single crystal. These cells are used in high quality solar panels and are very efficient in converting the sunlight into electricity. Monocrystalline solar panels produce the same power as a polycrystalline solar panel, however the cells of a monocrystaline solar panel tend to have a uniform appearance.
Monocrystalline solar cells are made out of silicon ingots, which are cylindrical in shape. To optimize performance and lower costs of a single monocrystalline solar cell, four sides are cut out of the cylindrical ingots to make silicon wafers, which is what gives monocrystalline solar panels their characteristic look.
Tend to perform better than similarly rated polycrystalline solar panels at low-light conditions.
