<p>The sensor based sun tracker solves the problem of reliable and low-cost automatic tracking of the sun along one axis or by using two sensor based sun trackers even along two axes. Its electronic logic for tracking the sun along one axis, consisting only of four resistive and two operational amplifiers, receives data on the location of the sun from the sun location detector (16) and switches the DC drive (10) of the tracking assembly on and off, where any solar collector is attached to, so that this solar collector is during the day always looking directly to the sun. At the same time this solar tracking device enables the early morning return of the solar collector back to the east and also an ultra precise tracking of the sun.</p> |
