Etude conception et réalisation d’un suiveur solaire biaxiale

Abstract

Our work has as objective the improvement of the gain in electrical energy of the solar tracker moving relative to the fixed system. Our instrument device will be fixed on a mechanical structure that we made based on two DC motors with their control circuits allowing rotation of the panel in both horizontal and vertical directions. For this application, we have made a telescope made of four photoresist sensors type 'LDR' which are arranged in such a way thattheir illumination is identical only if the telescope is pointed towards the sun. The signals from the sensors are transmitted to the inputs of a microcontroller of the type 'uno' in "arduino" which allows the comparison of the voltage levels for the control of the two motors. In addition, it allows the orientation of the panel towards the sun. Finally, the system we have achieved is able to follow the sun's rays and give a higher yield of electrical energy. Compared to the fixed system
