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.
This paper reviews the progress made in solar power generation by PV technology. Performance of solar PV array is strongly dependent on operating conditions. Manufacturing cost of solar power is still high as compared to conventional power.
Several methods have been developed to predict the solar PV array output power. An estimation method used in Ref. proposes that the power output of a PV system is proportional to the insolation levels measured for the surface of a solar cell at any angular position.
Solar PV is distinct from Solar Thermal and Concentrated Power Systems. Solar PV is designed to supply domestically usable power made possible by the use of photovoltaic. Photovoltaic (PV) as a process was first discovered in 1839 by Alexander Edmond Becquerel, while experimenting with a solid electrode in an electrolyte solution.
Photovoltaic power systems are gaining importance in distribution generation (DG) of renewable energy sources due to abundant availability of solar radiation as a source for generating electricity by the photovoltaic effect in semiconductors.
