Solar Photovoltaics (PV)
Solar Photovoltaics (PV) covers the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry.
A typical photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power. The first step is the photoelectric effect followed by an electrochemical process where crystallized atoms ionized in a series, generate an electric current. PV installations may be ground-mounted, rooftop mounted or wall mounted.
Solar PV generates no pollution. The direct conversion of sunlight to electricity occurs without any moving parts. Photovoltaic systems have been used for fifty years in specialized applications; standalone and grid-connected PV systems have been in use for more than twenty years.
