1. Photovoltaic (fo-to-vol-ta-ik) systems are solar systems that produce
electricity directly from sunlight. The term "photo" comes from the Greek
"phos," meaning light. "Voltaic" is named for Alessandro Volta (1745-1827), a
pioneer in the study of electricity for whom the term "volt" was named.
Photovoltaics, then, means "light electricity." Photovoltaic systems produce
clean, reliable electricity without consuming any fossil fuels. They are being
used in a wide variety of applications, from providing power for watches,
highway signs, and space stations, to providing for a household's electrical
needs. http://ping.fm/XaIrF
