Two-Axes Sun Tracking System : The Theory and Design

This book is aimed at designing and building a complete tracking system including mechanical structure, electronic controller circuit based on PIC, and robust program that can be adapted according to the location and the season (where one can chose the way of tracking either with a constant time or with constant number of moves in a day). It focuses on an astronomical equation to calculate the altitude and azimuth angles for two axes tracking system; to determine the sun position over the sky precisely at any time during the day for years (including the leap years) with different weather conditions, to avoid the loss of sun path as a result of partial cloudy weather for a part of the day, or of dusty weather for periods of the day
