StealthGen - Direct-Drive Wind Generator - Brochure

This is very dependent on the quantity and quality of the wind resource at your site. The higher the average wind speed at your location, the more power will be produced. Output from a single turbine at an open site with 5 m/s average wind speed should be over 400 kW hours annually. At a 6 m/s site, this would be close to 700 kW hours. At sites with average wind speeds below 3.5 m/s, yields from the system are likely to be under 200 kW hours annually, and alternative technologies such as photovoltaic panels may be preferable.
