The Sun can provide energy to power your life. Photovoltaic systems capture the photons from the sun and turn the photons into electric power. This is a chemical rection within the photovoltaic cell. The process which was discovered in the late 1800's was not considered a value until the 1950's. At that time NASA turned this little know power generation system into a useful source of electric power for satellites. Now some 55 years later we can depend on the sun to produce clean electric power for our homes and businesses.
