Design and Development of Solar Tracker and Cleaning Of PV System

Abstract

Solar energy is a form of renewable energy source and in the present scenario; it is the desideratum of the hour to efficiently utilize this energy source. The proposed work fixates on two mechanisms which can increase the efficiency of rooftop solar panels assembly. The two mechanisms employed are Solar tracker assembly and solar panel cleaning mechanism. Solar tracker assembly uses Light dependent resistor (LDR) to track and monitor the kineticism of sun. It sends the signal to arduino controller which then provides out signal to the tracker mechanism. It consists of a dc motor; the arrangement of tracker is predicated on a rope pulley mechanism which ascertains correct kineticism of the solar panel. Solar tracking mechanism ascertains maximum solar energy is absorbed by the solar panels. The solar panels are installed on rooftops or ascended platforms, there is no routine cleaning of these panels and dust gets accumulated over the time which decreases the absorption capacity of solar panels. Solar panel installation requires high initial investments and if these are not maintained it shall abbreviate the overall efficiency of solar panel systems. The proposed work presents a cleaning mechanism which ascertains the panels are cleaned routinely thus eschewing the accumulation of dust and minimization in Efficiency. These two mechanisms are employed in the project to have congruous utilization of renewable energy resource.
