Bergey WindPower is a pioneer of home wind power technology, with 30 years experience designing and manufacturing wind turbines. In an often volatile industry, Bergey WindPower stands out as a company you can rely on to maintain support for their products for decades to come.

Bergey’s Excel 6 wind turbine is well-suited for powering smaller remote homes and farms, with a peak power output of 6.7kW in 16.5m/s (36.9mph) winds. The included VCSII battery charger provides a maximum output of 65V @ 200A, with a normal output voltage range of 40–63V DC. The Excel 6 is one of two Bergey turbines (out of 9 total) to be certified by the Small Wind Certification Council (SWCC), documenting that it meets performance and safety standards established by the American Wind Energy Association (AWEA). With an industry-leading 10 year warranty, a Bergey Excel turbine is one of the safest investments you can make in a renewable energy system.

To order a complete turbine kit, simply select the best tower size for your installation location. The turbine should ideally be installed high enough that surrounding buildings or trees will not interfere with wind flow to the turbine. (You may also order a turbine without a tower, if you have sourced an appropriate tower elsewhere. See link below for requirements.)

From the manufacturer:

Smaller, more efficient farms and rural homes The Excel 6’s extra large rotor and ultra low cut-in wind speed make it an exceptional performer and a wise investment for smaller, more efficient farms and rural homes. Grants are available for agricultural producers and rural small businesses through the USDA’s Rural Energy for America Program. Small wind systems also qualify for accelerated depreciation, making it more affordable than ever for businesses to offset their electricity costs.
