The importance of bracket accessories in solar systems


Bracket accessories are an important presence in solar systems. Today we will talk about the products and installation of solar photovoltaic bracket systems. Do you know? What is the material of the solar photovoltaic mounting system? What are the required components? At present, the solar photovoltaic bracket systems commonly used in our country are divided in terms of materials, mainly including concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their large weight, they can only be placed in areas with good foundations, but they have high stability and can support large-sized solar panels. Aluminum alloy brackets are generally used for solar energy applications on roofs of civil buildings. Aluminum alloys have the characteristics of corrosion resistance, light weight, beautiful appearance and durability, but their low bearing capacity cannot be used in solar power station projects. In addition, the price of aluminum alloy is slightly higher than that of hot-dip galvanized steel.

The steel bracket has stable performance, mature manufacturing technology, high bearing capacity, and easy installation. It is widely used in civil, industrial solar photovoltaic and solar power stations. Among them, the section steel is produced by the factory, with uniform specifications, stable performance, excellent corrosion resistance and beautiful appearance. It is worth mentioning that the combined steel bracket system can be installed on site only by using specially designed connecting pieces to assemble the channel steel, the construction speed is fast, and no welding is required, thereby ensuring the integrity of the anticorrosive layer. The disadvantage of this product is that the connecting piece has a complicated process, a large variety, and high production and design requirements, so it is expensive.

Components of solar photovoltaic bracket

Divided from the connection method, the installation of the solar bracket can be simply divided into two types: welding and assembly. Welded brackets have low requirements for the production process of section steel (angle steel), good connection strength, and low price, which are currently used as bracket connection forms on the market. However, welding brackets also have some shortcomings, such as the difficulty of anti-corrosion at the connection points. If the paint is painted, the paint layer will peel off every 1 to 2 years, which requires repainting, and the subsequent maintenance costs are high. When it is installed in a remote area, the cost of welding power is high; the construction speed is slow, and it is not beautiful enough. With the improvement of the level of urbanization in our country, the residents have higher and higher requirements for the aesthetics of buildings. The photovoltaic support systems used in civil buildings are not suitable for welding supports.

In order to overcome these shortcomings, finished brackets with grooved steel as the main supporting structural component have appeared on the market. The significant advantage of the assembled bracket is that the assembly and disassembly speed is fast, no welding is required; all the bracket components are manufactured by the factory, the anticorrosive coating is uniform, and the durability is good; the construction speed is fast and beautiful. But it is not easy to achieve the above points.

First, to make the connection between the channel steels convenient, different splicing pieces and fixing devices must be designed according to various connection situations (as shown in the figure). The connection and fixing device must be capable of firmly connecting the assembly piece and the channel steel, which can be fixed and locked at any position of the channel steel, and is easy to install and disassemble. Secondly, the connection between the channel steels needs to be secure, such as by occlusion. *, The on-site cutting of the entire section of channel steel needs to be as accurate and convenient as possible, and the back hole cannot be cut. This requires channel steel to add scale marks to facilitate construction workers to cut on the spot.
