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.
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 adapter can be supplied to connect to the grid.
For over 20 years our clients who have deployed the STR sun-tracker, experience ease of set-up, operating and reliable tracking.
