How Solar Panels Work

Solar panels, also known as photovoltaic (PV) panels, are made up of numerous solar cells that harness the power of sunlight. When photons from sunlight strike these cells, they excite electrons, generating a flow of direct current (DC) electricity. Inverters then convert this DC electricity into alternating current (AC), suitable for use in homes and businesses.
