Preamble: This course gives a flavor of renewable sources and systems to the students. It introduces solar energy its radiation, collection, storage and its applications. This covers generation, design, efficiency and characteristics of various renewable energy sources including solar, wind, hydro, biomass, fuel cells and geothermal systems.
In this introductory chapter, fundamentals of solar thermal energy are discussed and some details concerning the sun, the star of our solar system and the source of solar energy on earth, are given. Further, solar thermal collectors available in the market are briefly presented, focusing in particular on concentrating collectors, systems able to concentrate and hence to increase the solar radiation. Among these, parabolic trough collectors (PTCs), which are the main subject of the present book, are described by dividing them into two different parts: the concentrator and the receiver. The materials used in such solar collector and their working principle are also discussed. Finally, typical solar thermal applications are presented, in particular as regards their utilization with PTCs.
