Photovoltaic solar energy directly converts sunlight into electricity through photoelectric effect. Aluminum is the most ideal material for photovoltaic solar energy. The unique lightweight and anti-corrosion properties of aluminum alloy make the device very convenient to move and have a longer service life. An'an Xincai contributes about 5000 tons of materials in the photovoltaic field every year, contributing a green force to China's green environmental protection.
