Product Description
450w Longi Solar Bifacial Module 166x166mm Half Cell LR4 72HPH 450M
Products Description
A monocrystalline solar panel is simply a solar panel made from monocrystalline solar cells or “wafers.” Monocrystalline wafers are made from a single silicon crystal that is formed into a cylindrical silicon ingot.
Although these panels are generally thought of as a premium solar product, the main advantages of monocrystalline panels are higher efficiencies and sleeker aesthetics.Because a monocrystalline cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move.
