This paper presents a procedure for the design and analysis of a solar tracking system for a given photovoltaic energy conversion installation which could readily be used by local designers. As the specifications of the desired energy consumption determines the actual total weight of the required number of solar panels, the proposed procedure aims at facilitating optimum choice of the drive servo-motor and presents a formalized design method for the associated controls. The overall transfer function of the system is developed and analyzed to investigate system stability and accuracy. Finally, a Computer -Aided-Design (CAD) algorithm for the optimum choice of the servo-motor and the design of the controls is suggested with the Volt/Ampere characteristics of the solar sensors and the mass of the solar panels as the only required input parameters.
