Dual Axis Solar Sun Tracking System Based on GPS Satellite Receiver and Embedded System

In this paper a solar sun tracking system for two axes solar cell is designed and implemented. The system derived by tow motors controlled by micro-controller. To achieve the sun tracking, three types of sun tracking methods is used. The first one is depending on the location of the tracker system this method requires embedded system, GPS system and mathematical calculation equation. The second type use sensor system to scan the horizontal and vertical axis to find out the locations of the sun and send its data to computing system. The third type is just depending on the time that is determined by computing system to drive the tracker. A data acquisition system and graphical user interface (GUI) software is designed to measuring and plotting all the data of the system. The result is compared with international software tracking program.
