This paper concerns the design and realization of a solar tracking system oriented to the PV conversion panels. In general, the electricity generated by the PV panels is influenced by the intensity of solar radiation and ambient temperature. They will generate maximum electrical power when the intensity of solar radiation received is also maximum, therefore the PV must be controlled so that its position is always perpendicular to the sun. The proposed single axis solar tracking system offers optimal energy conversion process of solar energy into electricity through appropriately orienting the PV panel in accordance with the real position of the sun. The mechanism of the experiment is based on a DC motor which is intelligently controlled by fuzzy logic controller that moves prototype according to the inputs received from LDR sensors. The performance of the solar tracking system is experimentally investigated. The …
