Types and applications of photovoltaic brackets
Photovoltaic bracket is a structure used in solar photovoltaic systems to support and fix solar panels, which is crucial for the stability and power generation efficiency of the entire system. The types of photovoltaic brackets are mainly classified according to materials and installation methods:
According to material classification
Aluminum alloy bracket: suitable for rooftop solar energy in civil buildings, lightweight and corrosion-resistant (based on actual reports), but with relatively weak load-bearing capacity.
Steel bracket: easy to install, suitable for speed, good appearance, suitable for various environments, especially large photovoltaic power plants.
Concrete bracket: With a large volume, it is commonly used in large photovoltaic power plants.
Classified by installation method
Fixed photovoltaic bracket: The photovoltaic array receives solar radiation in a fixed manner and can be divided into optimal tilt angle fixed type, inclined roof fixed type, and adjustable tilt angle fixed type according to the tilt angle setting.
Tracking photovoltaic bracket: By using electromechanical or hydraulic devices to move the photovoltaic array with changes in the angle of incidence of the sun, the power generation capacity is improved. According to the number of tracking axes, it can be divided into single axis tracking systems and dual axis tracking systems.
Technological progress and market trends of photovoltaic brackets
Photovoltaic bracket technology is constantly advancing, with tracking brackets becoming increasingly popular due to their ability to increase the power generation of photovoltaic modules. The tracking bracket can track the position of the sun in real time, ensuring that the photovoltaic modules always maintain a good angle with the sunlight, thereby improving power generation efficiency. It is predicted that the market penetration rate of public tracking brackets will continue to increase, and the compound growth rate will remain high in the coming years.
In addition, the application of composite material technology in the photovoltaic bracket market is also increasing. This technology replaces traditional metal materials with stable performance composite materials, achieving lightweight, higher strength, and corrosion resistance (based on actual reports) of brackets, and is expected to promote the sustainable development of the photovoltaic industry.
Design and installation requirements for photovoltaic brackets
The design of photovoltaic brackets needs to consider geographical, climatic, and solar resource conditions to confirm that the entire photovoltaic power generation system can achieve high power output. The design of the bracket also needs to consider weather resistance, structural stability, and the ability to withstand external effects such as atmospheric erosion, wind loads, and others. During the installation process, the verticality and levelness of the brackets, as well as the spacing and flatness between the brackets, need to meet specific requirements to protect the installation quality and power generation efficiency of the photovoltaic modules.
