DEVELOPMENT AND IMPLEMENTATİON OF A DUAL-AXİS TRACKİNG SYSTEM FOR

Abstract

In this article, we present a method to improve the efficiency of solar panels by based on an electro-mechanical  tracking system using an altitude-azimuth tracker that moves along two axes, one to scan the azimuth angle (β)  and the other to scan the tilt angle (α). This system is a development of fixed systems, working in two modes:  Tracking mode and Fixed mode. We will provide a comparison between the tracking mode and the fixed mode.  This system consists of the guidance base carrying the solar panel, two steering motors (‘push-pull’ type), a  Control & Driving System for the steering motors, and a Data Acquisition System (DAQ) to store the solar panel  data in a Multimedia Card (MMC). This system has been practically implemented and has achieved a 27.6%-  29.5% increase in efficiency compared to fixed systems, hence the importance of this system
