The material of solar PV bracket
At present, solar bracket supports commonly used inChinaare divided into concrete brackets, steel brackets and aluminum alloy brackets by materials.
The concrete bracket support is mainly used in large-scale photovoltaic power stations. Because it is self-important, it can only be placed in the wild, and the base is better, but the stability is high, and it can support the large-sized panels.
Aluminum alloy brackets are generally used in solar energy applications for residential buildings. Aluminum alloys are resistant to corrosion, light weight, beautiful and durable, but their self-supporting capacity is low and cannot be applied to solar power station projects. In addition, the price of aluminum alloy is slightly higher than that of steel with hot-dip galvanizing.
The steel bracket has stable performance, mature manufacturing process, high bearing capacity and easy installation. It is widely used in residential and industrial photovoltaic and solar power stations. Among them, the steel is produced in the factory, the specifications are uniform, the performance is stable, the corrosion resistance is excellent, and the appearance is beautiful. It is worth mentioning that the combination steel bracket system, its on-site installation, only need to use the specially designed connecting parts to assemble the channel steel, the construction speed is fast, no welding is needed, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this kind of product is that the connecting parts are complicated in process, various in variety, high in production and design, and therefore expensive.
