The bracket system is divided into three types: concrete bracket, steel structure bracket and aluminum alloy bracket.

Concrete mounting are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the wild and in areas with good foundations, but they have high stability and can support huge-sized solar panels.

At present, distributed photovoltaics are mainly used for steel structure mounting and aluminum alloy mounting .

The steel solar bracket has stable performance, mature manufacturing technology, high bearing capacity and easy installation. It is widely used in civil and industrial solar photovoltaic and solar power stations. Among them, the section steels are all factory-produced, 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 kind of product is that the connecting parts are complicated in technology, have a wide variety, and have high requirements for manufacturing and design, so they are expensive.

Aluminum alloy solar bracket are generally used in solar energy applications on the roof of civil buildings. 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. But for aluminum alloy flat roof solar racking, the price is more affordable.

Design requirements of the solar panel mounting systems:

1.Security

The structure can withstand various functions that may occur during normal construction and normal use, and can maintain the necessary overall stability when and after the occurrence of accidental events specified by the design.

2.Applicability

In normal use, it has good working performance. For example, it does not produce excessive deformation that affects normal use.

3. Durability

Since the components have a 20-year warranty period, our bracket correspondingly needs the same warranty period. Under normal maintenance, the structure has sufficient durability, such as material weathering, aging, and corrosion does not exceed a certain limit.
