important Questions to Ask When Shopping for a Small Wind System

Adapted from the June/July 2009 issue of Home Power Magazine,, 800-707-6585

Equipment manufacturers or their dealers should be able to answer the following questions about their products (see also

  • What is the energy output (measured in kilowatt-hours or kWh – not in kilowatts or kW) of the turbine, over one year, in average wind speeds of 8 to 14 mph?  Is this calculated using real-life ("field") data (preferred), or laboratory / wind tunnel testing?
  • Can you refer me to other customers who have owned [Model X] for a period of time?  (The longer, the better.)
  • What is the warranty length and coverage (industry standard is 5 years)?
  • Has the turbine/tower ever gone through a reliability test?  By whom?  For how long?  What were the results?
  • How long has the company been producing turbines?
  • How long has [Model X] turbine been available to sale to ordinary customers – not in the prototype or beta testing phase?
  • For how long was the prototype tested?  By whom?  In the field or in a laboratory?
  • How many turbines of [Model X] been sold, and for how many years? How many of these are still running?
  • How frequently has [Model X] been redesigned?  What were those changes and how recent were they?
  • What problems have other customers encountered and how have you dealt with them?

The American Wind Energy Association (AWEA) has compiled the following list of U.S. manufacturers and suppliers of wind turbines for use in residential, farm, and commercial/industrial applications. Many have Web sites or are accessible through E-mail links. Links are also provided to the company listings on the AWEA Industry Member Directory.

The following is a list of turbines that are eligible for financial incentives by the California Energy Commission and/or the New York State Energy Research and Development Authority, and are AWEA Corporate members (see and, and/or are determined by AWEA's Small Wind Turbine Committee as commercially available with multiple publicly accessible operational installations in the U.S.:

AEROSTAR wind turbines utilize induction generators allowing simple direct utility interconnection without the need for an inverter.  The two blade teetering rotor substantially reduces loads on the turbine and tower resulting in a smooth running, efficient and low cost system.  Although the turbine design goes back to the early 1980s, the design incorporates the latest advances in materials and technology.  Advances include variable generator excitation control which substantially improves energy capture at low wind speeds, aerodynamic rotor control to ensure safe operation and acoustic isolation of moving parts for extremely quiet operation.  All systems are available with a color touch screen display, data logging of wind speeds and turbine output and an Ethernet interface so you can monitor your turbine performance from anywhere in the world.
