Rotary solar ground mount

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.
