Solar Panel Energetic Efficiency Optimization Method, based on an Specific Detector and Orientation Microsystem

The increase of the solar cells efficiency implies high technological and scientific efforts. A significant efficiency increase of the photovoltaic panels can be also obtained by optimal exposure of the panels to the sunlight, using automatic solar trackers. For wide scale use of these control systems, it is very important to find low cost and reliable solutions. In the current paper we propose a low cost tracking procedure, based on differential method and special microdetector. This solution permits a simple solar panels return from west to the east, within the angle regulation range of 0-180deg.
