How Do Photovoltaic Work?
PV solar panels create power by converting sunlight into electricity — producing clean energy. A PV cell or solar cell is the semiconductor device that converts sunlight into electricity. These cells are combined to form panels which, in turn, are combined to create what are called arrays — the solar generation systems which connect to the energy grid. The efficiency of each solar panel is measured by its ability to absorb light particles called photons. The more photons that are absorbed, the more efficient the panel is at converting light into electricity. When photons strike the solar cells contained in a solar panel, they can be reflected, absorbed, or pass through the panel. When photons are absorbed, they have the energy to knock electrons loose, which flow in one direction within the panel and exit through connecting wires as solar electricity, ultimately providing power.
