The book provides a comprehensive exploration of solar photovoltaic (PV) systems, covering essential concepts such as the mechanics of solar cells, output characteristics, and the impact of temperature on efficiency. It delves into the role of diodes in PV systems, including bypass and blocking diodes, and discusses charge regulators and system controls. Additionally, it addresses the sizing of PV systems, including DC/AC inverters and battery storage solutions, while also touching on other renewable energy sources like wind, biomass, and tidal energy.

The research emphasizes the significance of alternative and renewable energy sources in India, particularly through hybrid energy systems. It introduces a proposed hybrid model combining Wind, Solar, and Diesel Generator systems, comparing stand-alone and grid-connected setups. Subsequent chapters delve into the wind energy conversion system, detailing theoretical concepts, modeling in MATLAB/Simulink, and providing simulation results. The solar energy conversion system is also explored, with derived mathematical equations and discussions on Maximum Power Point Tracking (MPPT), supported by references at the end of each chapter.
