How is PV solar energy generated?
Photovoltaic solar energy is produced when the sun’s energy, in the form of photons, strikes a photovoltaic cell and is transmitted to electrons within the semiconductor material in the PV cell, causing an electrical current. Each photovoltaic cell generates only a small amount of energy, so many cells are grouped together into a module; then several modules are combined to form a solar panel. Many solar panels place together, for example on a roof, is called an array.
