slewing drive solar tracker

The slewing drive for solar traker is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together

The solar tracking system is divided into Horizontal single-axis solar tracking system, Tilted Single-Axis Tracker and Dual axis solar tracking system. 

For horizontal single-axis solar tracking system, the main shaft of solar panel will adjust the angle to precisely track the declination angle. This kind of slewing drive is only applied for low latitudes area.

Dual axis solar tracking system is " altitude angle + azimuth" full-tracking system, it moves along two rotation axes with two rotational degrees to completely track the sun's orbit and maximize solar energy reception. This kind of slewing drive is suitable for high-latitude areas and the efficiency of power generation will be increased over 35%, which significantly improve the efficiency of solar power generation system.
