Your site should have an average annual wind speed of 7 mph or greater. Check www.windpowermaps.org, local weather information, or install an anemometer to determine your wind resource. We can provide a reasonably priced anemometer to assess your wind resource. If the wind is often a nuisance, you probably have a good wind resource!
-
The wind system tower should be at least tall enough so the bottom of the wind turbine blades are 30 feet above any obstruction within 500 feet laterally. Wind speed increases with tower height, and power output increases dramatically with greater wind speed. Taller towers are better! Tilt up towers make erecting and servicing wind turbines much easier.

If you have less than one acre, a wind system tower may take too much space.
We are a Bergey Windpower (www.bergey.com) Certified Dealer.
Bergey wind turbines are very quiet (see the National Renewable Energy Lab (www.nrel.gov) small wind turbine noise study), and reliable. Impacts on birds and bats are practically non-existent for the small wind turbines we sell.
The latest studies on avian impacts can be found
at the American Wind Energy Association
(www.awea.org) web site.
We are also dealers for Abundant Renewable Energy (www.abundantre.com) which offers new small and medium wind turbines.
We can perform a site assessment and install a wind turbine to meet your needs, either grid
tied or off grid (Living Off Grid.pdf).
In Chelan County, the Chelan County PUD (www.chelanpud.org/SNAP) Sustainable Natural Alternative Power (SNAP) (SNAP Synopsis.pdf) will purchase power from your grid tied wind system for up to $1.50/kWh! We pay only $.028/kWh for grid power.
If you are not located in Chelan County, ask your utility if they have a similar renewable energy
buy back program.
In addition, wind power Green Tags (environmental attributes) can be sold for $.04/kWh.
Contact Northwest SEED (www.nwseed.org) for details.
