Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
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.
The Solar Photovoltaic Cell (Solar Cell) converts sunlight (photons) into electrons as Direct Current (DC). Photo means light, while voltaic means electricity; light-electricity is its literal meaning. The PV power system at the first instance, generates DC, which is not constant and fluctuates with sunlight intensity or lack of.
A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as controllers, meters, and trackers. Most panels are in solar farms or rooftop solar panels which supply the electricity grid.
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.
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.
