­Small Wind Turbine Models Certified for the U.S. Market 

Updated July 2018

The IRS issued Guidance PGP-130597-11, which provides performance and quality standards that small wind property must meet to quality for the energy tax credit. The guidance states that the small wind energy property must meet the performance and quality standards as set for in either of the following:

  • American Wind Energy Association Small Wind Turbine Performance and Safety Standard 9.1-2009 (AWEA); or
  • International Electrotechnical Commission 61400-1, 61400-12, and 61400-11 (IEC).

This listing first provides a list and ratings for turbines certified to the AWEA standard and then provides a list of turbines certified to the IEC standards.

 Ratings of AWEA Certified Small Wind Turbine Models

The small wind turbine models below are fully certified to the AWEA Small Wind Turbine Performance and Safety Standard (AWEA Standard 9.1 – 2009), with power performance ratings, sound level ratings and design and duration test compliance.

 

1 Estimated annual energy production assuming an annual average wind speed of 5 m/s (11.2 mph), a Rayleigh wind speed distribution, sea-level air density, and 100% availability. Actual production will vary depending on site conditions.
2 The sound level that will not be exceeded 95% of the time, assuming an annual average wind speed of 5 m/s, a Rayleigh wind speed distribution, sea-level air density, 100% availability and an observer location 60m from the rotor center.

3 Power output at 11 m/s (24.6 mph) at standard sea-level conditions. Manufacturers may describe or name their wind turbine models using a nominal power, which may reference output at a different wind speed (e.g., 10 kW Bergey Excel 10).
