WebPhotovoltaics. Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels. WebWhen sunlight hits a solar panel, it is absorbed by the PV cells. The photons from the sun’s rays knock electrons off the silicon atoms in the PV cells, creating a flow of electricity. …
