How Does A Solar Panel Produce Energy

Solar panels use the photons produced by sunlight to generate direct current dc electricity.

How does a solar panel produce energy.

Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. Solar panels work by allowing particles of light called photons to knock electrons from their atomic orbitals. When this occurs a flow of electricity is generated and this electricity is harnessed and preserved as electrical energy.

Energy from the array is sent through an inverter which transforms the initial direct electrical current into the alternating electrical current required to power human made structures. During this process electrons separate from the atoms and move around the solar cell. When the photons hit the panel they are absorbed by the panel s semiconducting silicon material. This all happens as light hits a unit called a photovoltaic cell.
