Optimizing solar panel energetic efficiency using an automatic tracking microdetector

Increasing energetic efficiency of solar power plants implies high technological and scientific efforts every year. A significant efficiency increase of these systems can be also obtained by optimal exposure of the panels to the sunlight, by using automatic solar trackers. For wide scale use of these control systems, it is very important to find reliable and low cost solutions. In the current paper we propose a low cost tracking procedure, based on amplitude comparison method and a special signal microdetector, made with MEMS technology. The procedure permits simple rotations of the panel based on complete tracking, by azimuth and elevation. The possible regulation angle is in the range of 30 -150°.
