Solar cells are a sheet filled with hundreds of tiny receptors that are sensitive to the Sun’s energy. The solar cells use these receptors (Photovoltaic Receptors) to create electricity with the Sun’s light. The photons in the Sun’s light knock off the electrons on existing atoms inside of the solar cell. That causes an electric current! Electricity is basically the flow of electrons! The solar panels then convert the energy that is produced into electricity that can be used in homes. Solar energy is a sustainable and reliable type of energy source because it is always there and does not pollute the environment. This is how solar energy works!
