Rural
Electrification - In Cacimbas, Brazil, 50-watt PV systems provide
homes with electricity for fluorescent lighting. This approach
bypasses the need for creating utility grid, providing reliable
power where it is needed. (R. Taylor/NRELPIX 01270)

9.6
kW Photovoltaic System at Pinnacles National Monument, California.
The system provides power for three employee residences, a ranger
station, visitor center, campground, comfort station, well pump,
and two wastewater effluent pumps. It eliminates a $20,000 annual
fuel bill for a diesel generator that produced 143 tons of carbon
dioxide each year. (National Park Service/NRELPIX 04924) |

Prototype
of a high-altitude, long-endurance, solar-powered aircraft.
These aircraft could potentially provide the means to creating
a stratospheric satellite system. In contrast to traditional
satellites, such a system concentrates capacity directly over
populated regions, allows for routine maintenance & technology
upgrades, and can provide an economic solution in parts of the
world lacking existing telecommunications infrastructure. (photo courtesy of NASA/Dryden, info: www.aerovironment.com)

 100
kW PV PowerGuard system provides both power and added insulation
to the Mauna Lani Bay Hotel in Hawaii. The unique system requires
no roof penetrations for mounting. (Powerlight/NRELPIX)
