Photovoltaic stents are generally divided into three types according to materials, including aluminum alloy brackets, steel brackets and concrete brackets. The photovoltaic supports of these three materials are very different in terms of application. Firstly, the aluminum alloy brackets are better for solar energy on the roof of civil buildings, and there are many more, but its bearing capacity is poor, so it cannot be used in On the power plant. Compared with the aluminum alloy bracket, the steel bracket is simple and quick to install, and the appearance is relatively beautiful. Finally, the concrete support is a relatively large photovoltaic support, which is mostly used in large-scale photovoltaic power plants.
