Solar photovoltaic bracket is the cornerstone of the solar system, especially for rotating type of solar energy, higher request to the photovoltaic stents, of course, its utilization is also higher.

Many kinds of solar photovoltaic stents, aluminum alloy and steel and so on, different materials, made to support performance is also different, therefore, in the actual application, need to choose the right bracket to install. Now it's time to compare their performance.

Aluminum light quality, beautiful appearance, excellent anti-corrosion properties, general used for bearing the roof of the request the power station, chemical plants, strong corrosive environment such as aluminum alloy stents will have better effect. Steel, high strength, bear load deflection deformation small, commonly used in ordinary circumstances of power plant or parts for stress is larger.

In terms of cost, in general, the basic wind pressure in 0.6 kN/m2, span under 2 m, aluminum alloy stents cost for steel structure of 1.3 to 1.5 times. In small span system, (e.g., choi steel roof) aluminum alloy stents with steel structure cost difference is small, and the aluminum alloy in terms of weight, much lighter than the steel bracket, so it is suitable for power plant roof.
