Solar pv mounting bracket is the cornerstone of solar energy systems, especially for the rotation of solar energy, the requirements for the PV bracket higher, of course, its utilization is also higher.
There are many types of solar pv bracket aluminum alloy and steel, etc., different materials, made out of the stent performance is not the same, therefore, in practical applications, the need to select the appropriate bracket to install. Now let's compare the performance.
Aluminum profiles light weight, beautiful appearance, excellent corrosion resistance, generally used for load-bearing roof power station, strong corrosive environment, chemical plants and other aluminum alloy stent used to do will have better results. High strength steel, under load deformation deflection is small, generally used for general power plant or for the relatively large force components.
In terms of cost, in general, the basic air pressure at 0.6kN / m2, span in the 2m below the cost of aluminum alloy stent for the 1.3-1.5 times the steel structure. In the small-span system (such as color steel roof) aluminum frame and steel structure cost difference is relatively small, and in terms of weight aluminum alloy is much lighter than the steel bracket, it is very suitable for roof power station.
