Single Axis VE9 Slew Drive Gearbox For Solar Tracking System With 24vdc Planetary Gear Motor
Description
Horizontal single axis solar tracking systems direct PV solar panels or solar modules toward the sun. The slewing drives can change their orientation throughout the day to follow the sun’s path to maximize energy capture, thus improving the electricity yield.
The horizontal single axis solar tracking system is suitable for most areas and help minimize the angle of incidence between the incoming light and the panel, which increases the amount of energy the solar tracking system produces.
The vertical slewing drives which is applied in horizontal single axis tracking system are widely used.

Selection of Slewing Drive
When selecting a suitable slewing drive, we need a brief information about the solar tracking system:
1. The scale of the projects. For utility-scale and large projects usually use horizontal single-axis solar trackers, while dual-axis trackers are mostly used in smaller residential applications.
2. The load on the slewing drives and its gravity distance
3. The output speed
