Increasing The Efficiency of Photovoltaic Systems

The aim of this book is to present a way in which the efficiency of solar power collection can be increased. It is to increase the efficiency of solar power conversion by increasing the amount of time that the solar panel is directly perpendicular to the sunlight. New technique of solar tracking using solar-powered Stirling engine as the power source for the tracking motor are presented. Efficiency is based on accurately positioning the solar panel throughout the day and thus motors and Light Dependent Resistors (LDR) have been selected as the primary driving mechanism of this system. This book presents a Sun tracking design, whereby the movement of a photovoltaic module was controlled to follow the Sun's radiation using a Light Dependent Resistors (LDR) and the power source of PV tracking are coming from solar-powered Stirling engine. The results will decrease the power for operating solar tracking system by selecting the solar-powered Stirling engine as the power source for motor of solar tracking system. All electronic circuits and the necessary software have been designed and developed to perform the technical tasks.
