Book excerpt: Fundamentals of Renewable Energy Systems goes beyond theoretical aspects of advances in renewable energy and addresses future trends. By focusing on the design of developing technologies, relevant operation and detailed background and an understanding of the application of power electronics and thermodynamics processes in renewable energy, this book provides an analysis of advancing energy systems. The book will be of interest to engineering graduates, researchers, professors and industry professionals involved in the renewable energy sector and is ideal for advanced engineering courses dealing with renewable energy, sources, thermal and electrical energy production and sustainability. With increasing focus on developing low carbon energy production, audiences need to have the engineering knowledge and practical skills to develop and implement creative solutions to engineering problems encountered with renewable energy technologies. By looking at renewable energy capture and conversion, system design and analysis, project development and implementation, each modular chapter examines recent advances in specific renewable energy systems with detailed methods, calculations and worked examples. - Includes recent techniques used to design and model different renewable energy sources (RES) - Demonstrates how to use power electronics in renewable systems - Discusses how to identify, design, integrate and operate the most suitable technologies through key problems
