Power for the Beard residence outside Reno, Nevada is
provided by a Bergey XL.1 1,000 W wind turbine, 1,000 W of solar, and a 12 kW
back-up generator. Besides the usual complement of high-efficiency lights
and appliances found in typical off-grid homes, the Beard home is
air-conditioned. The system was installed in December, 2002 by Alternative
Energy Solutions in Reno. This was a difficult installation due to the
sloped terrain and the rocky soil. The XL.1 is installed on a 13m (42 ft)
Tilt-up tower. BWC recommends against installing on a slope, if possible,
because of the slanted wind flow through the rotor, but in this case the hill
behind the house was the only area available for the turbine. Note the
above ground electrical conduit and custom rock anchors required due to the
rocky soil.
