Design and Fabrication of Automatic Single Axis Solar Tracker for Solar Panel

Abstract

Sun energy is a considered to be one of most promising source to address the world energy crises. Photovoltaic cell is one of the prominent sources of energy. The most important factors that affect the efficiency of solar cells are cell temperature, maximum power point tracking (MPPT) and energy conversion efficiency. The optimization of these factors improves solar cells efficiency for more reliable applications. This study associated by means of the designing and manufacturing process of single axis tracker device by using photo voltaic conversion panels. This solar tracker system assures the conversion optimization of electricity from the source of sun energy by proper using of orientated photovoltaic panel in a manner conforming to the actual direction of sun. Experimental system based on the function of DC motor, which is controlled by dedicated drive astutely so as to move the PV panel in accordance with the signals be given as of effective light sensors. It has been found that at the same sunny day the energy output of solar panel with tracking system was 1742.88Wh and with non tracking system was 829.6Wh.
