Wind Power Generation Products
For 20 years, Southwest Windpower has been bringing low-cost, reliable wind energy to the world. Trehab Renewable Energy is pleased to be the NEPA/Upstate NY dealer for their products. We offer grid-connected systems as well as battery-charged systems for remote locations. Click on any of the products below for more information.
The all-new Air Breeze Land. Quieter, more efficient, and precision engineered to deliver more energy at lower wind speeds than any other wind generator in its class.
Learn MoreThe Whisper Series provides dependable energy for remote homes, telecommunications sites and rural applications in moderate to extreme environments. This Series is scaled for production of 100, 200 or 500 kWatts/Month with an average 12mph wind.

More information we think you should know:
Nameplate ratings tell you nothing about how much power a turbine will produce. Some small turbines have nameplate ratings. For example, a turbine might be called 10 kW, 5 kW or 25 kW. The nameplate rating describes the rated capacity of the turbine at a particular wind speed. A 10 kW turbine might produce 10 kW at a 30 MPH wind speed. A 25 kW turbine might produce 25 kW at a 26 MPH wind speed. These numbers do not tell you how much power the turbine will produce at the average wind speed at your location. There are few, if any, locations where a small wind turbine will be installed where the average wind speed is 25 or 30 MPH. Most locations where small turbines will be installed have average wind speeds in the 10-14 MPH range.
No wind turbine can extract more than 59.6 % of the energy from the wind. In 1919, a German physicist named Albert Betz determined that a wind turbine cannot convert more than 59.6% of the energy in the wind to mechanical or electrical energy. The reason for this is that wind turbines extract energy from the wind by slowing the wind. For a turbine to be 100% efficient it would have to reduce the wind velocity to zero. If you were to stop the wind there would be no wind to turn the rotor.
This is also called the “efficiency” rating that Trehab Renewable Energy will tell you about. It exists for ALL wind turbines.
