A solar panel works by allowing photons, or particles of light to knock electrons free from atoms, generating a flow of electricity. Solar panels comprise of many smaller units called photovoltaic cells. Many of these cells are linked together to make up a solar panel.
Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon that is mixed with elements phosphorous and boron, which create conductivity within the cell and activate the movement of electrons.
The electrons move across the cells when are activated by the sunlight’s energy into the electrical circuit hooked up to the solar panel. Therefore, the power produced by a PV array (group of solar panels) increases with the intensity of the light striking it.
