Pv supporting brackets are divided into three types: concrete supports, steel supports and aluminum alloy supports.
Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations. However, they have high stability and can support large-scale solar panels.
Aluminum alloy brackets are generally used in solar energy applications on civil building roofs. Aluminum alloy has the characteristics of corrosion resistance, light weight, beautiful and durable, but its low self-carrying capacity cannot be applied to solar power station projects. In addition, the price of aluminum alloy is slightly higher than that of hot-dip galvanized steel.
The most used kind of pv supporting bracket, steel bracket has stable performance, mature manufacturing technology, high bearing capacity and easy installation. It is widely used in civil or industrial solar photovoltaic and solar power stations. Among them, the section steel is produced in the factory, with uniform specifications, stable performance, excellent corrosion resistance and beautiful appearance. It is worth mentioning that the combined steel bracket system, for on-site installation, only needs to use specially designed connectors to assemble the channel steel. The construction speed is fast and no welding is required, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this product is that the connecting piece has a complicated process, a wide variety, and high requirements for manufacturing and design, so it is expensive.
