I've been hearing a lot about the benefits of solar energy, but I'm not sure I understand how it works. Can you give me some more information on this?

Solar energy is derived from sunlight which is converted into electrical energy using photovoltaic (PV) cells. These cells are made up of semiconductors that absorb photons from the sun and produce an electric current. The electricity can then be used to power homes, businesses, and other devices.
