Photovoltaic bracket is an indispensable part of photovoltaic power generation system, the following is a detailed introduction of photovoltaic bracket:
Definition and function
Photovoltaic bracket is a special bracket for installing, placing, carrying, fixing and adjusting photovoltaic modules in photovoltaic power stations. It forms a photovoltaic power generation system together with photovoltaic modules, bus boxes, inverters and other core equipment. Photovoltaic bracket is an important support structure for carrying photovoltaic modules, and its safety and installation convenience are the core requirements. At the same time, the performance of photovoltaic support has an important impact on the power generation efficiency, investment income, maintenance costs and so on.
Second, type and material
1. Type: photovoltaic bracket can be divided into three types: fixed, adjustable Angle and automatic tracking. Fixed bracket is divided into roof bracket, ground bracket and water bracket; The automatic tracking bracket is divided into single-axis tracking bracket and dual-axis tracking bracket.
2. Material: At present, there are mainly three kinds of materials on the market: hot-dip galvanized, galvanized aluminum magnesium, weathering steel. Among them, hot-dip galvanized bracket is a more common anticorrosive material; Galvanized aluminum-magnesium bracket has the characteristics of incision self-healing and corrosion resistance, which is suitable for harsh environment; The weathering steel bracket has the mechanical properties of high-quality steel and atmospheric corrosion resistance, and is environmentally friendly, low-cost and maintenance-free.
Third, installation and maintenance
1. Installation: The installation of photovoltaic brackets needs to follow certain steps and specifications, including preparing construction tools, selecting the appropriate installation location, assembling brackets, installing inclined beams and reinforcing structures. During the installation, ensure that the support is at a right Angle to the ground and secured by connecting parts such as stainless steel bolts.
2. Maintenance: After the installation of photovoltaic bracket components, regular inspection, cleaning and maintenance and protection should be carried out. This includes checking whether fasteners are loose, whether the welding is intact, whether the anti-corrosion coating is intact, etc.; Clean the surface of the bracket assembly to keep it running efficiently; The support is protected to extend its service life.
4. Selection and economic indicators
The selection of photovoltaic support will directly affect the economic indicators, construction land indicators and construction scale of photovoltaic power stations. Therefore, when choosing a photovoltaic bracket, it is necessary to consider many factors such as its performance, cost, durability and installation convenience.
In summary, photovoltaic bracket plays an important role in photovoltaic power generation system, and its type, material, installation and maintenance, selection and economic indicators are key factors affecting the performance and investment return of photovoltaic power stations.
