The Wattsun AZ-225 Gear Drive, azimuth tracker automatically tracks the sun by rotating the PV array about the pipe mast. Then it tilts for elevation. The Dual-Axis Option (included) enables it to capture virtually all the power the sun delivers.

Compared to passive, tilt and roll trackers, azimuth trackers provide greater stability for large arrays. The corners do not protrude down towards the ground or stick up in the air to catch the wind. The bottom edge of the array always remains parallel to the ground and requires less ground clearance than tilt & roll designs.
