Product Description
The arc-shaped pull-rod type manual adjustable inclination ground photovoltaic support is an innovative support system developed based on the fixed support. This system introduces an arc-shaped pull-rod adjustment mechanism on the single-column fixed inclination support, enabling the photovoltaic modules to be manually adjusted in the north-south direction according to the changes in the solar seasonal angle, thereby increasing the amount of solar radiation vertically incident on the surface of the photovoltaic modules, and significantly improving the power generation efficiency of the power station.
Compared with traditional fixed supports, this product does not require motor drive. It can achieve flexible adjustment of angles through manual operation, ensuring system stability while significantly reducing equipment costs and subsequent maintenance expenses. Compared with expensive tracking supports, this product has a simple structure, high reliability, and high land utilization rate. It is a cost-effective solution between fixed supports and tracking supports.

Advantage
▶ The arc-shaped pull rod adjustment structure is easy to operate
This product uses a circular arc pull rod as the core adjustment mechanism. By setting multiple positioning holes on the arc-shaped pull rod and cooperating with the pins on the column for fixation, it precisely locks the angle of the photovoltaic panel support. During the adjustment process, simply pull out the pin, push the pull rod to the desired angle (any position within the range of 0° to 40°), and then reinsert the pin to complete the adjustment. This structural design makes the manual operation very convenient and safe, and it can be completed by only two people for the angle adjustment of the entire array.
▶ High-strength material, durable and resistant to corrosion
The main components are made of Q235B carbon steel, and their surfaces are treated by hot-dip galvanizing or galvanizing with aluminum-magnesium. This process ensures excellent corrosion resistance, effectively preventing rust and aging. The supports are of high hardness and good stability, and are not prone to deformation or cracking, with a long service life. The fasteners are made of zinc-nickel alloy or stainless steel SUS304, ensuring the long-term reliability of the connection nodes.
▶ Structural optimization design, with efficient installation
The system has a simple structure with few components and easy connections. The main components are prefabricated in the factory, and only fasteners are needed for on-site assembly and connection to complete the installation. The foundation can be prefabricated, further shortening the on-site construction period. Each array only requires a small number of columns, effectively reducing the amount of foundation and installation costs.
▶ The power generation efficiency has significantly improved
Compared with fixed installation systems, seasonal inclination adjustment can increase power generation by 3% to 10%. Users can select the optimal inclination angle within the range of 0° to 40° based on the longitude and latitude of the project location and astronomical conditions, achieving the maximum utilization rate of light resources.
▶ Low maintenance cost
Pure manual operation, without the need for electrical drive devices such as motors and controllers, there are no potential mechanical faults caused by electrical control, and the maintenance cost is extremely low. The arc pull rod structure avoids the problems such as easy wear of the screws and screw sleeves in the traditional screw jack-type support, and the angle fixing mechanism is also reliable.

Applicable Scenarios
▪ Large-scale ground-based photovoltaic power station:
This product is specifically designed for large-scale commercial and public utility power stations, and is widely applicable to various terrains such as plains, hills, and mountains. Thanks to its flexible design and manual adjustment function, it can maximize power generation efficiency under different regional and climatic conditions.
▪ Seasonal adjustment demand scenario:
Applicable to projects that need to adjust the component inclination according to seasonal changes. It can be adjusted 2 or 4 times a year. In low-latitude regions, a smaller inclination (such as 0°–15°) can be set to cope with seasons with larger solar altitude angles. In high-latitude regions or snowy areas, it can be adjusted to a larger inclination (such as 30°–40°) to optimize winter light reception and promote snow sliding.
▪ For cost-sensitive medium-sized and large-scale projects:
No electrical equipment such as motors and controllers is required. The system cost is basically the same as that of the fixed support structure, while it can significantly increase the power generation capacity. This is particularly suitable for ground-based power station projects that aim to optimize the return on investment.
▪ Projects with high terrain adaptability requirements:
The slope in the east-west direction can be adjusted within ±15°, and there is no limit on the slope in the north-south direction. They can be flexibly arranged on irregular land to increase land utilization.
Summary
The arc-shaped pull rod type manual adjustable inclination ground photovoltaic support is an innovative support system specially designed for large-scale ground power stations. It realizes manual inclination adjustment within the range of 0°–40° in the north-south direction through the arc-shaped pull rods and the pin positioning mechanism. No motor drive is required, and the operation is convenient (one person can complete it). The cost is basically the same as that of fixed supports, but it can optimize the component's light reception angle according to seasonal changes, increasing power generation by 3%–10%. The main body of the support is made of Q235B carbon steel and undergoes hot-dip galvanizing or galvanized aluminum-magnesium treatment, which is sturdy, durable, and has excellent corrosion resistance. It can adapt to various terrains such as plains, hills, and mountains, and is compatible with mainstream framed/unframed components and horizontal/vertical layouts.
The core feature of this product lies in the "arc-shaped pull rod", which integrates adjustment and structural support. This not only avoids the defect of traditional screw-type adjustment that is prone to wear, but also simplifies the system structure and significantly reduces operation and maintenance costs. At the same time, it overcomes the drawbacks of complex and expensive tracking brackets and low land utilization rate. It achieves the best balance between initial investment and long-term returns, making it an ideal ground-based photovoltaic solution that combines reliability, economy, and power generation efficiency.
