The Difference Is In What's On Top
The three-bedroom, two-bath house on the Florida Solar Energy Center grounds in Cape Canaveral is very much like millions of other homes in the nation with one exception--photovoltaic cells (solar cells) mounted on its south roof convert sunlight to electricity to meetmuch of the house's power needs. Photovoltaic cells are truly "magical" devices, a direct product of the modern day, space age technology. Each of this facility's I68 photovoltaic modules contains 35 four-inch-diameter solar cells. In bright sunlight, the enttre roof can generate more than 5,000 watts ofelectrrcity at a level of about 200 volts.
