Abstract: The aim of this paper is to introduce a novel solar tracking alternative whose principle is based on continuous tests comparing the produced thermal energy corresponding to the new apparent sun position with the electrical energy consumption required to drive the solar collector to the new position. Accordingly, the sun-tracking occurs whenever the net energy gain, the gap between thermal production and electrical consumption, is higher than an optimal threshold which reflects the required limits from which the sun-tracking process should begin. The proposed approach was investigated through modeling and optimization. Furthermore, to check the accuracy of the theoretical model, a series of comparisons were also performed, which have shown a reasonable agreement between the simulation results and the available data in the literature.
