Backtracking Self Powered Single Axis Tracker Controller
Working principle:
Single axis tracker controller which is mainly applied in the mid
and low latitude areas, In single axis solar trackers, a long
horizontal torque tube is supported on bearings mounted upon
frames. PV modules are mounted upon the torque tube, and the tube
will rotate on its axis to track the apparent motion of the sun
through the day. At medium and low latitude region, it increases
investment about 5-8%, while promotes generating capacity by
15%-25%.
With our solar tracker control system you maximize your return on
investment by cutting installation time and maintenance cost. Our
controller makes sure that your panels are pointing the sun at best
in any weather condition to maximize the energy output, and
minimize the energy spent to move the tracker.
