Solar panels are devices that convert sunlight into electricity. They are made up of solar cells, also called photovoltaic cells, which are fitted in a series of rows and columns to form a solar panel.
When sunlight hits the solar cells, it loosens electrons from their atoms. This allows the electrons to move freely which, in turn, generates a flow of electricity that can be used to power homes and businesses or charge batteries.
Energy generated by solar panels can be stored in batteries, in order to use the energy during cloudy and rainy days, at night or during power outages.
