Solar Panel Systems
Photovoltaic, or PV for short, is a solar power technology that uses solar cells to convert light from the sun directly into electricity. This unique process uses no moving parts, thereby nothing can wear out. To explain the photovoltaic solar panel more simply, photons from sunlight knock electrons into a higher state of energy, creating electricity.
Photovoltaic solar cells use the energy of the sun’s light to cause electrons to move between layers of a semi-conductor material, such as silicon. Once moved, the electron wants to return, but cannot jump back. It gets back by flowing through wires and circuits which creates electron flow or direct current (DC) electricity.
