Product Description
This product is a new type of photovoltaic ground mounting system that combines the stability of a fixed structure with the flexibility of a manual adjustable system. The core design lies in the precise combination of horizontal rotating bearings and hand-crank transmission mechanisms, enabling the inclination angle of the entire table to be quickly, uniformly, and synchronously adjusted through an artificial crank handle. The equipment does not rely on an external power source and can be installed and used immediately.

Advantage
▶ Significant increase in annual power generation:
Compared with fixed structure, by manually adjusting the inclination angle quarterly, the equivalent utilization hours throughout the year can be significantly increased, and the investment payback period can be significantly shortened.
▶ Zero electricity cost and maintenance-free:
The solution is pure mechanical transmission structure, which avoids the paralysis problem of tracking system caused by power input failures. No motors or electronic controllers. Less maintenance required in the later stage, especially suitable for harsh outdoor environments.
▶ Optimal cost-performance:
It combines the increase gain from adjustable angle with the low cost advantage of the fixed type mounting structure, making it one of the best choices for obtaining the more power generation benefit at the lowest cost.

Applicable Scenarios
▪ Seasonal adjustment demand scenario:
The solution is applicable to the projects that need to adjust the module 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.
▪ Remote areas without electricity and independent power supply systems:
No need to build complex power grids or install expensive electric drive equipment. Manual operation can be used to manage the inclination angle of the photovoltaic panels.
Summary
This is an innovative photovoltaic ground mounting bracket system based on pure mechanical transmission. The core design lies in the ingenious integration of the rotating bearing and the manual drive mechanism, eliminating the need for external power sources. Operators only need to manually rotate the hand crank to simultaneously drive the inclination angle of the entire row of photovoltaic arrays to be adjusted within the range of 0° to 60°, precisely matching the solar radiation angles of different seasons. In terms of structure, it uses high-strength alloy steel, with long-term anti-corrosion treatment, with a design lifespan of over 25 years and excellent wind resistance and snow load capacity.
It fundamentally avoids the pain point of electric tracking systems being unable to operate due to electrical failures, and through simple seasonal adjustments, it can significantly increase the annual power generation compared to ordinary fixed structure, greatly shortening the investment recovery period.
Carbon steel ground solar module mounting strucutre - ground screw pile foundation: The core material is galvanized or Zn-Al-Mg coated steel. It consists of screw piles buried underground, and the mounting structure above ground. The ground screw pile is installed by piling machine by screwing into the soil to serve as the load-bearing foundation for the photovoltaic array. All components are treated with hot-dip galvanizing or ZAM coating, achieving full metal connection.
