The compact 2-arm STR-22G sun tracker is perfectly suited to support all kinds of Global, Diffuse and Direct Radiation measurement sensors. Besides the standard EKO sensor mounts, various alternative mounts for non-EKO sensors are available. Featuring a fully automated set-up procedure via an onboard GPS receiver, providing increased reliability and enhanced functionality, the compact Sun-Tracker guarantees accurate sun tracking and pointing of the attached solar sensors from sunrise to sunset.

The 2-axis tracker automatically adjusts to the sun’s position by the sun sensor closed-loop control system, even if the tracker is not oriented or levelled properly. The sun-tracker comes standard with a small table tripod (larger tripod available). The 24 VDC low power consumption tracker can be powered by a solar-powered battery system or DC power supply. A wide range AC power adapters can be supplied to connect to the grid.

For over 20 years, clients who have deployed STR sun-trackers have enjoyed easy set-up, smooth operation, and reliable tracking.
