What kind of material should photovoltaic bracket choose?
Abstract：Photovoltaic bracket is the support structure of solar array, and the choice of its material directly affects the performance, cost, life and maintenance difficulty of photovoltaic system. The following are some of the selection and analysis of photovoltaic bracket materials:
Photovoltaic bracket is the support structure of solar array, and the choice of its material directly affects the performance, cost, life and maintenance difficulty of photovoltaic system. The following are some of the selection and analysis of photovoltaic bracket materials:
Material types and characteristics
The materials of photovoltaic bracket are mainly stainless steel, aluminum alloy, super thick hot dip galvanized and so on. Stainless steel bracket has the advantages of corrosion resistance, high strength, mature production process and high bearing capacity, but the weight is larger and the installation and transportation cost is higher. Aluminum alloy bracket has the characteristics of light weight and beautiful use, but the bearing capacity is low, can not be applied in solar power station projects. The super thick hot-dip galvanized bracket has excellent anti-corrosion function and beautiful appearance, but the cost is high.
The climatic and environmental conditions of different regions require materials
The climate and environmental conditions of different regions have different requirements for the material of photovoltaic brackets. For example, in areas with windy sand and dry climate, it is necessary to choose a bracket with strong wind resistance and corrosion resistance; In the earthquake-prone area, it is necessary to select the support with good seismic performance. In the special terrain conditions such as swamp and desert, it is necessary to choose the support with high bearing capacity and stability.
Material costs and economic benefits
In addition to performance and scope of application, the cost and economic benefits of the material are also factors that need to be considered when selecting photovoltaic brackets. Although the stainless steel bracket has high bearing capacity and stable performance, it has high cost and is suitable for large-scale photovoltaic power stations and projects requiring high-quality and high-precision production processes. The aluminum alloy bracket has the advantages of low cost and light weight, which is suitable for distributed photovoltaic projects with low bearing capacity requirements. The ultra-thick hot-dip galvanized bracket has excellent anti-corrosion function and beautiful appearance, but the cost is high, and it is suitable for photovoltaic projects requiring high-quality and high-precision anti-corrosion function.
Conclusions and recommendations
In summary, the selection of photovoltaic bracket materials needs to be judged and selected according to the specific project needs and environmental conditions. Stainless steel bracket is suitable for large photovoltaic power station projects with high bearing capacity requirements and harsh climatic conditions; The aluminum alloy bracket is suitable for distributed photovoltaic projects with low bearing capacity requirements; The ultra-thick hot-dip galvanized bracket is suitable for photovoltaic projects requiring high quality and high-precision anti-corrosion function.
In the selection of photovoltaic bracket material, you also need to pay attention to the following points: First, to choose the quality of reliable raw materials and manufacturing processes to ensure the structural strength and service life of the bracket; Secondly, it is necessary to carry out regular cleaning and maintenance, remove ash and dirt, and keep the surface of the support clean and smooth; Finally, it is necessary to regularly check the connectors and welding places of the bracket, and timely deal with problems such as loosening and damage to ensure the structural stability and safety of the bracket.
In addition to the material selection and analysis mentioned above, there are some new materials and technologies are also emerging, such as carbon fiber reinforced plastics (CFRP) and intelligent monitoring systems. The application of these new materials and technologies can further improve the performance and economy of photovoltaic supports, and bring more opportunities and challenges to the development of the photovoltaic industry.
