Harnessing a multitude of complementary green energy sources is the only plausible way to satisfy the energy demands of a greedy global economy. The potential of solar energy (being the most abundant) in fulfilling part of the energy requirements of mankind is immense and constitutes the focal point of this book. A self-powered solar tracker that points directly towards the sun by means of an integrated control mechanism with two degrees of rotational freedom was studied and developed. The electro-mechanical control system is based on a precisely-timed microcontroller circuit that first computes the altitude and azimuth of the sun in real-time and then drives a pair of stepper motors that steer the solar tracker towards it. A locally built fibre-glass parabolic dish, the surface of which is lined with a reflective vinyl mirror film, serves to concentrate solar rays on its surface.

This book provides a technical overview of low-cost parabolic trough collector (PTCs) prototypes for low-temperature heat demand. It begins with a comprehensive but concise summary of the state-of-the-art in PTCs, and presents a detailed mathematical model of such systems. Subsequent chapters describe the construction and materials used in the manufacture of PTC prototypes, and offers technical solutions to overcome design problems. Finally, it provides an accessible guide to the standards used to test and evaluate the performance of PTCs. Offering a valuable resource to engineering researchers and practitioners, it is also suitable for students of solar thermal systems, renewable energy and applied physics.
