Solar power cells convert sunlight into clean electricity, using the energy of photons to create an electrical current within a solar panel or group of panels. Photons are created in the center of the sun by the fusion of atoms. The energy from the sun is never ending, and has powered the earth for millennium - redistributing and refreshing water systems and feeding plants.
For decades, researchers have been learning to harness this energy source with more efficiency and have been successful. Solar power is efficient and like wind will not create unnecessary pollution, noise, and is technology becoming more cost-effective every year.
