A Prototype Model for Generating Electricity Using Solar Parabolic Dish, Stirling Engine and Solar Tracking System

Abstract

Energy crises refers to any shortfall in the supply of energy resources to an economy. To counter these crises, renewable energy resources provide a significant potential. As most of the renewable energy resources never die, so we can obtain continuous supply from these sources. Among these sources, solar energy provides greater potential for electrical power. To use solar energy, one of the best approach is to design Parabolic Solar Dish which is more efficient than other solar technologies. In order to get maximum power output, needs to keep the dish aligned with the sun. This paper deals with the generation of electricity using parabolic shaped dish. A model is designed which contains a solar parabolic shaped dish, Stirling engine, dynamo and a solar tracker. Solar energy is focused on the cylinder of a Stirling engine which is attached at the focal point of the dish. This Stirling Engine is coupled to a Dynamo through a rubber belt and the dynamo produces output. Moreover a Solar Tracker Circuit is designed which rotates the dish automatically in the direction of sun. This reduces the use of fossil fuels and have greater efficiency.
