We are Official Authorized of Longi solar, supply all series of Longi solar panels:Half Cell Solar Panel 370-380W 440-455W, Half Cell Double Glass Bifacial Solar Panel 360-380W 440-455W, 535W-540W
Solar panels, also known as photovoltaic (PV) panels, are advanced devices designed to convert sunlight into clean, renewable electricity. Composed of numerous high-efficiency solar cells typically made from silicon, these panels harness the sun's energy to produce a flow of electric current. This current is then transformed into usable alternating current (AC) by an inverter, providing power for homes, businesses, and industrial operations.
The primary benefits of solar panels include:
