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.

The Bergey Excel-10R off-grid wind turbine offers the output you need to power your home or farm with a single independent power source. The EXCEL-10R has a rotor diameter of 23 feet (7m), and peak power output over 10K watts. Between the standard marine-grade corrosion protection, and Bergey’s Autofurl protection (which protects the turbine from damage in high winds), the EXCEL-10R turbine is a powerful and durable addition to any off-grid power 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.)
