The book provides practice-oriented information on analysis, design and installation of photovoltaic power systems. It starts with a brief overview of large-scale photovoltaic technology and the power electronics devices used in current state-of-the-art systems. The main part of the book is devoted to the setup of and electrical installation in photovoltaic power plants according to international standards and regulations with a focus on achieving safe operation by proper implementation of protection measures, e.g., against overvoltages and overcurrents. The last part deals with simulation and test procedures and presents design case studies.
