A photovoltaic system is the power system that supplies usable solar power through photovoltaics. It involves the conversion of the sun's radiation into usable electricity. Photovoltaic systems can be categorized into grid-connected, rack mounted, distributed, ground-mounted, building-integrated photovoltaic systems, etc. It comprises of various components such as solar array, cabling, mounting, tracker, etc. A photovoltaic system can range from building-integrated systems having a capacity of several tens of kilowatts to large utility-scale power stations having a capacity of hundreds of megawatts. This book aims to shed light on some of the unexplored aspects of the photovoltaic systems and the recent researches in this field. The various studies that are constantly contributing towards advancing technologies and the evolution of such systems are examined in detail. Researchers and students in this field will be assisted by this book.
