Principle of solar PV power generation
In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) strike solar cells. The process is called the photovolatic effect.

At its core, PV relies on the principle of the photovoltaic effect, where certain materials generate an electric current when exposed to sunlight.
A PV cell is made of materials that can absorb photons from the sun and create an electron flow. When electrons are excited by photons, they produce a flow of electricity known as a direct current.
Solar power plants use one of two technologies:Photovoltaic (PV) systems use solar panels, either on rooftops or in ground-mounted solar farms, converting sunlight directly into electric power.Concentrated solar power (CSP) systems use mirrors or lenses to concentrate sunlight to extreme heat to make steam, which is converted into electricity by a turbine.
PV modules produce direct current (DC) power, which is typically converted to AC using inverters. A solar cell is a device that transforms solar radiation into electricity in a single step.
