STR-21G Sun Tracker
The compact sun tracker is perfectly suited to support all kinds of Global, Diffuse and Direct Radiation measurement sensors. Besides the standard EKO sensor mounts, various mountings are available. EKO Instruments improved STR-21G with fully automated set up the procedure through a GPS receiver providing increased reliability and enhanced functionality.
From the sun rise to the sun set 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 levelled properly.
The Sun Tracker comes with a small tripod that offers a stable surface for the measurement equipment. When AC power is not available on site a 24 VDC low power version can be used to run the EKO Sun-Tracker from a solar powered battery system.
