This book is centered on contemporary fundamental techniques for collecting solar radiation and the prospective applications that show how solar energy concentrators (SEC) can be used in a variety of systems and may provide significant economic and environmental benefits.   Around the globe, there is a tremendous drive to investigate the viability of utilizing solar energy, particularly in regions with temperate zones. The usage of solar energy in many sectors has grown over the years. The ongoing quest for an alternate energy source in response to the apparent depletion of fossil resources is the driving factor behind this transition. Fossil fuels are far more widely used now than ever before despite their rising price. Although all forms of renewable energy are accessible, solar radiation is the most prevalent and easily accessible. Using solar energy for higher processing temperatures is difficult despite being the most common clean and affordable renewable energy source on the planet. For this, solar energy concentrators (SEC) are a promising technology that could be used to harness both heat and electricity for diversified industrial operations. SECs are devices that harvest solar radiation and direct it to a single point of concentration.   This book presents the most up-to-date fundamental strategies for the collection of the sun's radiation. Moreover, SEC technical summaries are also evaluated concerning ongoing international assignments. Prominent applications are also featured to show the reader the scope of the SEC's applicability. The potential implementations demonstrate that CSE can be employed in a wide range of systems and may offer considerable economic and environmental advantages. By the end of this book, one will learn more about the significance of solar energy concentrators, the technologies that are related to them, and their plethora of applications.
