High Torque VE7 Vertical Single Axis Solar Slew Drive For Tilted
Tracking System
ingle Axis Solar Slew Drive Description
The rotation axis of the oblique single-axis tracking bracket is
installed at an inclination angle to the horizontal plane, and it
rotates around a one-dimensional axis. The direction of the
rotation axis is north-south, so that the light-receiving surface
of the photovoltaic module is as perpendicular to the incident
angle of sunlight as possible in the one-dimensional direction.
