Solar racking is a key component of a solar power system. It is custom-designed according to geographic location, climatic conditions, and solar energy resources, and is used to support and secure the solar modules, ensuring that they are arranged at the optimal angle and spacing. This structure not only affects the safety and efficiency of the system, but is also directly related to the construction and maintenance costs. Proper selection of solar mounting types can effectively reduce project investment and minimize O&M expenses.
Solar racking is mainly divided into three categories: fixed, tilt-adjustable and auto-tracking. Fixed racking can be subdivided into roof type, ground type and water type racking according to the different installation environments. Among them, roof mounts include color steel roof mounts, pitched roof mounts, flat roof mounts and BIPV solar building integrated mounts. The auto-tracking type of racking mostly adopts oblique single-axis tracking technology to maximize the efficiency of solar energy utilization.
BIPV (Building Integrated Photovoltaic Valve) is a technology that synchronizes the design, construction and installation of solar power systems with buildings. It not only perfectly integrates the solar energy system with the building, but also has the function of power generation and the aesthetic value of the building.As part of the external structure of the building, the BIPV racking assumes the dual roles of power generation and building components.
Color steel roof racking is an important part of BIPV system, which consists of color steel clamps, rails, module presses and other components. With its solid structure and easy installation, it can effectively support solar modules and ensure their efficient operation. Flat roof mounts are similar to ground mounts, usually based on concrete and fixed by anchor bolts, which are easy to install and do not damage the waterproof layer.
Single-pillar mounts and double-pillar mounts are suitable for different terrain conditions. Single column bracket has simple design and is suitable for complex terrain; double column bracket has even force and is suitable for flat area. The single-pillar bracket is suitable for areas with high water table or rich vegetation, with simple structure and easy installation.
Water-based racking is an innovative form of distributed solar power generation, including floating type, column type and marine solar energy and other types. Floating mounts are composed of floats and brackets, providing excellent stability and impact resistance; column mounts are exposed to the water through high columns to ensure efficient operation of solar modules.
The tilt-adjustable mount adds an adjusting mechanism on the basis of the fixed mount, and the tilt angle can be manually adjusted according to the season or demand, thus improving the power generation efficiency. Auto-tracking mounts, on the other hand, make solar arrays always perpendicular to the sun’s rays by means of oblique single-axis tracking technology, which significantly improves power generation.
When choosing solar racking, it is necessary to consider factors such as weather resistance, installation safety, post maintenance cost and recyclability. Fixed mounts are easy to install, low cost and suitable for most scenarios; tilt-adjustable mounts can increase power generation but face technical challenges; auto-tracking mounts have the highest power generation efficiency but have higher investment and maintenance costs. Choosing the right solar racking according to actual needs can maximize the economic benefits and energy output of the system.
