Rotating manual tilt adjustable photovoltaic support system, with pure mechanical hand-winding drive, supports continuous adjustment of tilt angle from 0° to 50°. It does not require electricity and is maintenance-free in the long term. It achieves a power generation gain close to that of electrically-driven supports at a lower cost of the fixed support, and is widely applicable to agricultural-photovoltaic integration and small and medium-sized ground photovoltaic power stations.

Product Description
This product is a new type of photovoltaic ground installation system that combines the stability of a fixed support with the flexibility of a manual tracking 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 photovoltaic array 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. It is an ideal balance solution for a wide range of distributed photovoltaic power stations and agricultural photovoltaic complementary projects, achieving a high and power generation gain.

Advantage
▶ Significant increase in annual power generation:
Compared with fixed supports, by manually adjusting the inclination angle quarterly (Vernal Equinox, Summer Solstice, Autumnal Equinox, Winter Solstice), 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:
Pure mechanical transmission structure, avoiding the paralysis problem of tracking caused by power failures. No motors or electronic controllers. Almost no maintenance required in the later stage, especially suitable for harsh outdoor environments.
▶ Optimal cost-performance:
It combines the adjustment gain of the expensive "double-axis/flat single-axis tracking frame" with the low cost advantage of the "ordinary fixed frame", making it one of the best choices for obtaining the maximum power generation benefit at the lowest cost.

Applicable Scenarios
▪ Solar and Wind Power Integration Project / Fish Farm and Solar Power Integration Project:
The distance between the support structure and the ground is sufficient to ensure that the crops below receive normal sunlight and grow properly, and the manual adjustment does not harm the plant roots.
▪ Small and medium-sized industrial and commercial rooftop and ground-based power stations:
The project owners are highly sensitive to the electricity generation revenue and hope to enhance the overall power generation efficiency of the photovoltaic system at an extremely low marginal cost.
▪ 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.
▪ Top of the seasonal agricultural greenhouse:
According to the light and shading requirements of different crops, the transparent and covered area of the photovoltaic panels on the roof of the greenhouse can be flexibly adjusted.
Summary
This is an innovative photovoltaic ground installation system based on pure mechanical transmission. The core design lies in the ingenious integration of the top thrust rotating bearing and the manual lever drive mechanism, eliminating the cumbersome process of disassembling screws on traditional fixed supports and eliminating the need for external power sources. Operators only need to manually rotate the lever to simultaneously drive the inclination angle of the entire row of photovoltaic arrays to be adjusted within the range of 0° to 50°, precisely matching the solar radiation angles of different seasons. In terms of structure, it uses Q235B/Q355B high-strength alloy steel, combined with hot-dip galvanizing and long-term anti-corrosion treatment, with a design lifespan of over 25 years and excellent wind resistance and snow load capacity.
In practical applications, this support structure boasts the significant advantages of "zero electricity cost and near-zero maintenance", perfectly fitting various scenarios such as agricultural and photovoltaic co-generation, remote areas without electricity, and small and medium-sized ground-based power stations. 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 supports, greatly shortening the investment recovery period. Overall, it achieves "close to the power gain of electric supports" with the "affordable cost of fixed supports", making it the most cost-effective and high-quality photovoltaic installation solution that balances economic efficiency, reliability, and practicality.
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.
