Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power. At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. The "photovoltaic effect" refers to the conversion of solar energy to electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power.
