Important Questions to Ask When Shopping for a Small Wind System

Equipment manufacturers or their dealers should be able to answer the following questions about their products :

  • 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?

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.

Cascade Engineering, Inc. is the exclusive distributor for the SWIFT Wind Turbine in North America, as well as the manufacturer of  all SWIFT rotors sold worldwide.  SWIFT provides urban and suburban businesses and homeowners in favorable wind environments an effective, quiet, structure-mounted solution for lowering energy bills and reducing carbon emissions- helping to preserve the environment. The emphasis of the SWIFT design has been focused on safety, reliability, and ease of operation, alongside the high-performance of this innovative system. Mounting brackets and a patented diffuser ring minimize vibration during operation. In addition, the five blade design allows for a slower speed of rotation to further reduce noise and vibration, making the SWIFT Wind Turbine one of the quietest wind systems available.  The SWIFT Wind Turbine operates at 35 dB or less at any wind speed measured at the hub/center of the wind turbine, and the sound is significantly reduced by the outer ring that diffuses the air flow around the rotor. With installations worldwide and five international patents, this design icon has been quietly generating clean energy for homeowners, community groups, and commercial customers for over five years. The SWIFT is a grid-tied, closed-component system mounted on an aluminum mast with a minimum blade-roof clearance of 2 feet. The external inverter, mounted inside the home or building, allows for ease of access by the owner. Built on unique, patented technologies the SWIFT Wind Turbine is the most versatile wind turbine of its kind- silent enough to perch on a home, yet robust enough to secure to a skyscraper.

Ventera Energy Inc. is the maker of the new VT10, a 10kW, Grid Tied Wind Turbine manufactured in Duluth, MN.  The VT10 produces enough energy to completely eliminate the need to buy electricity for a typical farmhouse, producing between 1,000 to 2,000 kilowatt-hours per month with a good wind resource.  This cutting edge system is the product of more than 30 years experience in the small wind industry.  The VT10 uses the first ever dual wind and solar input, dual peak power tracking Synchronous Inverter capable of creating a 12 kW Hybrid system.  The patented governing mechanism protecting the VT10 in high winds not only allows it to survive wind speeds of more than 100 mph but (unlike competitors) to continue producing at near peak levels while doing so.   The VT10 uses a freestanding, tilt down tower with a total footprint of only 5 to 13 feet.   Not using guy wires radically reduces the amount of land needed, and the dangerous job of  having to climb the tower is completely eliminated.  The direct drive design drastically reduces preventative maintenance by using very few moving parts, with sealed bearings throughout and no gearbox to lubricate.  Rather than every 6 months as on many systems, preventative maintenance on the VT10 is once every 3 to 5 years.
