This is an economical photovoltaic bracket installation solution suitable for industrial and commercial rooftops. The photovoltaic bracket is made of aluminum alloy and stainless steel, with excellent corrosion resistance. The installation angle of photovoltaic modules can be increased on the roof to improve the power generation efficiency of photovoltaic power stations, which can be divided into three series: 10-15 °, 15 ° -30 °, 30 ° -60 °.
