Abstract: This chapter presents the important features of solar photovoltaic (PV) generation and an overview of electrical storage technologies. The basic unit of a solar PV generation system is a solar cell, which is a P‐N junction diode. The power electronic converters used in solar systems are usually DC‐DC converters and DC‐AC converters.
Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
A basic photovoltaic system integrated with utility grid is shown in Fig. 2. The PV array converts the solar energy to dc power, which is directly dependent on insolation. Blocking diode facilitates the array generated power to flow only towards the power conditioner.
Photovoltaic solar panels are devices specifically designed for the generation of clean energy from sunlight. In general, photovoltaic panels are classified into three main categories: monocrystalline, polycrystalline and thin-film panels.
