What are the types of solar photovoltaic bracket installation

What are the types of solar photovoltaic bracket installation

Although solar photovoltaic power generation is a new energy source, through practical application and the development of production technology, the types of solar photovoltaic supports that most manufacturers can produce include: fixed installation (fixed, fixed manually adjustable), single-axis installation (flat single, inclined single axis), and double-axis installation; These three types of mounting brackets have their own advantages. Fixed installation is also called fixed photovoltaic bracket: once the angle of this type of installation is fixed, the angle of the solar panel will no longer change, or by manually changing the installation angle. Single-axis installation refers to a photovoltaic bracket with a rotating device. At present, common ones include flat single-axis photovoltaic panel brackets and oblique single-axis photovoltaic brackets. Although the solar angle can be automatically adjusted, the rotation angle has certain restrictions. The two-axis installation is the two-axis tracking solar photovoltaic support. In this way, the photovoltaic module moves along two rotation axes, which can track the azimuth angle and altitude angle of the sun at the same time. Theoretically, it can completely track the running track of the sun to achieve vertical incidence and maximize the reception of solar radiation.

Surface support

Surface support

With the continuous advancement of distributed photovoltaic power generation projects, making full use of the sea, lakes, rivers and other water resources to install distributed photovoltaic power plants, and realizing new forms of photovoltaic agriculture such as complementary fishing and light, has become an important way to solve the problem that photovoltaic power generation is limited by land resources. There are generally two types of water surface supports: floating type and column type. The floating support is composed of two parts: float and support. The pontoon is made of high-strength materials and has a conjoined design, which has good stability and impact resistance, and can effectively prevent water flow and wind from causing damage to the photovoltaic module. The bracket is generally made of stainless steel, aluminum alloy and other materials, with strong corrosion resistance. The column type bracket is similar to the ground type bracket structure, except that the column is longer to ensure that the bracket is exposed to the water. At the same time, it is also important to choose a material that has the ability to resist corrosion in the water for a long time.

Ground support

Ground support

The ground support can be divided into three categories: single column support, double column support and single column support. The single-column support only needs a single-row column support, and each unit only has a single-row support foundation. It is mainly composed of columns, inclined supports, guide rails (beams), component pressing blocks, guide rail connectors, bolt washers, nut sliders and other components. The columns are made of C- shaped steel, H-shaped steel or square steel pipes. This kind of support can reduce the amount of land construction, suitable for complex terrain area. The double-column support adopts the form of front and rear columns. It is mainly composed of front column, rear column, inclined support, guide rail (beam), rear support, component pressing block, guide rail connector, bolt washer, nut slider and other components. It is made of C- shaped steel, H-shaped steel, square steel pipe and round steel pipe in strict accordance with the size of the square array. This kind of bracket has the advantages of uniform force and simple processing, and is suitable for areas with relatively flat terrain. The single column support only needs one column to support one square array unit. Since the entire square array only needs one column to support, the number of photovoltaic modules that can be arranged on a single frame is small, generally 8, 12 or 16. It is mainly composed of columns, longitudinal beams, guide rails (beams), component pressing blocks, guide rail connectors, bolt washers, nut sliders and other components. Among them, the column can be made of steel pipe, precast cement pipe and other materials, the longitudinal beam and cross beam are made of square steel pipe, and the guide rail is made of C- shaped steel or aluminum alloy. The support is suitable for areas with high groundwater level and lush ground vegetation.

Classification and Design of Fixed Photovoltaic Support

Photovoltaic support is a kind of support structure, according to the specific geographical location of photovoltaic power generation system construction, climate and solar energy resource conditions, the photovoltaic modules are arranged in a certain direction and angle and fixed spacing. As an important part of photovoltaic power generation system, photovoltaic support directly affects the operation safety, damage rate and construction investment of photovoltaic modules. Choosing the right photovoltaic support can not only reduce the project cost, but also reduce the maintenance cost. Photovoltaic support can be divided into three types: fixed, angle adjustable and automatic tracking, the connection method generally has two forms of welding and assembly. The fixed bracket includes a roof bracket, a ground bracket and a water surface bracket. Automatic tracking bracket is divided into single axis tracking bracket and two axis tracking bracket.
