Introduction of PV support knowledge

Our understanding of photovoltaic power generation should all originate from solar power generation? However, according to the data analysis, the expenditure of large solar power stations on photovoltaic support is not high. Generally, the solar power station selects the photovoltaic bracket with good quality rather than expensive price. How much do you know about PV supports? Now let me introduce you!

There are many kinds of common PV supports. Assembled type and welded type are two common connection modes of PV support. Day-by-day type and fixed type are two common types of PV supports classified according to the installation structure. Roof type and ground type are two common photovoltaic supports classified according to installation location. Generally, the components of PV supports are similar. The components of general PV support include keels, connectors, beams, auxiliary parts and columns. So what criteria should be used when selecting PV support? One of the criteria for selecting PV support components is that they must be resistant to climate change. Generally, consumers will choose the photovoltaic bracket that has been used for a long time. Generally, solar power stations require that the PV support purchased must have 25 years of effective use. Generally, the PV support must be firm and reliable during use. When the PV bracket is placed outdoors, it means that the PV bracket must withstand the erosion of external climate such as wind and snow. In addition, attention should be paid when installing the PV bracket to ensure the maximum use value while saving costs. For example, when installing the PV bracket, pay attention to the convenience of maintenance. At present, some high wear-resistant materials have been added to the production of PV supports, which has enhanced the corrosion resistance and resistance to wind and snow of PV supports. These materials include stainless steel, aluminum alloy, ultra-thick hot galvanizing, etc.

(1) The steel support has been widely used in civil and industrial solar photovoltaic and solar power stations due to its stable function, sophisticated manufacturing technology, high bearing capacity and simple installation. In the meantime, the profile steel is produced in the factory, with consistent standards, safe and stable functions, excellent anti-corrosion functions and beautiful appearance. Especially for the combined steel support system, its field devices only need to use the specially described connectors to assemble the channel steel. The construction speed is fast, without welding, and then ensure the integrity of the anti-corrosion coating. The defects of the combined steel support system are that the process of connectors is messy, the variety is complex, and the demand for production and description is high.

(2) The aluminum alloy bracket is usually used in the application of large solar energy on the roof of civil buildings. The aluminum alloy has the characteristics of corrosion resistance, light weight and beautiful use. The common brand is 6063 alloy. However, its bearing capacity is low and cannot be applied in solar power plant projects; In addition, the price of aluminum alloy is higher than that of hot-dip galvanized steel.

(3) Concrete supports are mainly used in large photovoltaic power stations. Because of their serious nature, they can only be placed outdoors in areas with good foundation; However, it has high safety and stability, and can support large-scale battery panels.

At present, the materials used for solar support include hot-dip galvanized steel frame, stainless steel frame and aluminum alloy photovoltaic support; Generally, solar cell modules are installed outdoors, so the support will have problems such as sun and rain, corrosion, rust and salt damage; In addition, at present, the weight of the bracket of a solar cell module is between 16 and 30 kg, and the load is considerable after multiple groups of modules are assembled. Therefore, the durability and lightweight of the scaffold is the future trend.

Europe and the United States have developed solar brackets made of plastic materials, and have gradually replaced the metal brackets in some parts and actually installed and used them. Its composite business division uses carbon nanotubes to add plastic materials, which can improve the strength and corrosion resistance of plastic, and develop plastic solar brackets with corrosion resistance and high strength.

Industry insiders said that the plastic solar support developed by the company can be equivalent to aluminum alloy in strength, and its weight is 1/3 lighter than aluminum, and it has high weather resistance and high corrosion resistance, so it does not need to increase the cost of anti-corrosion treatment. Because of its light weight and large plasticity, it can be integrated with the architectural appearance to design, and also reduce the floor load.
