The compact 2 arms 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. EKO Instruments improved the STR-22G Sun Tracker with a fully automated set up procedure through a GPS receiver, providing increased reliability and enhanced functionality.
From sunrise to sunset the compact Sun-Tracker guarantees accurate sun tracking and pointing of the attached solar sensors. 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 leveled properly.
