Photovoltaic brackets are mainly used to support and fix photovoltaic panels, that is, solar panels. It can help photovoltaic panels face the sun at the optimal angle, thereby absorbing more sunlight and improving power generation efficiency.
The material of photovoltaic brackets is usually steel, which is the "skeleton" of photovoltaic brackets. These steels will undergo special surface treatments, such as hot-dip galvanizing, galvanized aluminum magnesium, etc., to enhance their corrosion resistance and service life. Among them:
Hot dip galvanized bracket: It is quite common, generally with a thickness greater than 2mm, and can reach 2.5mm in windy areas. The cost is relatively high, but it has a long service life, high strength, and good stability.
• Galvanized aluminum magnesium support: the cut can be self-healing, the metal surface is resistant to chlorine, alkali, abrasion and corrosion, which can better cope with the harsh environment of desert, mudflat, saline and alkaline land, etc., with good quality and low price, which can save costs and improve the safety of the power station.
In addition to steel, there are also photovoltaic brackets made of materials such as aluminum alloy on the market. Aluminum alloy brackets are relatively lightweight, only about one-third the weight of steel brackets, but have lower strength and toughness, and are also more expensive. However, it has good corrosion resistance and is not easy to rust, making it suitable for use in photovoltaic systems such as seaside and color steel roofs.
There are also many types of photovoltaic brackets. According to the installation method, it can be divided into fixed brackets and tracking brackets. The orientation of the components of the fixed bracket is fixed, but can be manually adjusted according to the changes in lighting in different seasons; The tracking bracket can automatically track the position of the sun, keeping the photovoltaic panel facing the sun at all times, but the price will be higher.
In addition, according to different application scenarios, photovoltaic brackets can also be divided into roof brackets, ground brackets, agricultural photovoltaic system brackets, etc. They are designed according to specific environments and needs to ensure that photovoltaic panels can generate electricity stably and efficiently.
In the manufacturing cost of photovoltaic brackets, raw material costs account for more than 70%, of which half comes from steel. The weight of the bracket may also vary due to factors such as material, design, and scale.
The application range of photovoltaic brackets is particularly wide, from large-scale ground photovoltaic power stations to household rooftop photovoltaic systems, to agricultural photovoltaic systems, and so on, its presence can be seen. It is an indispensable part of the photovoltaic power generation system, carrying the stability and efficiency of the entire power generation system.
