The power systems that are designed to supply usable solar power using photovoltaics are referred to as photovoltaic systems. There are various types of modern photovoltaic systems such as grid-connected photovoltaic systems, stand-alone photovoltaic systems, building integrated systems, rack-mounted systems, residential and utility systems, roof-top and ground-mounted systems and many more. The photovoltaic system is made up of an arrangement of various components. It uses solar panels to absorb the sunlight and convert it into electricity. It also uses a solar inverter to convert DC into AC, as well as other electrical accessories such as mounting and cabling to set up a working system. Photovoltaic systems use a solar tracking system to improve the overall performance of the system. This book elucidates the concepts and innovative models around prospective developments with respect to photovoltaic systems. It presents researches and studies performed by experts across the globe. Those in search of information to further their knowledge will be greatly assisted by this book.
