The 3000-watt Whisper 500 turbine will deliver in excess of 500 KWH per month in a 12 mph wind. This machine has a 14-foot (4.26m) rotor diameter providing 175 sq. ft. of swept area. This model has been redesigned, incorporating a stronger, larger yaw shaft, new blade stabilizer straps and a third spindle bearing for increased reliability.

The Whisper 500 features a fiberglass and foam core blade for smooth, high efficiency operation and low wind start-up. It also incorporates the patented "angle governor" design for quiet operation in high winds. The Whisper 500 is an excellent machine for village power projects, farms, ranches, back-up power and remote homes with large energy demands.

Southwest Windpower has a series of tower kits especially for the AIR wind module and Whisper wind turbines.  Each tower kit comes with all the hardware necessary to install your tower although you must provide pipe and cement.  Installation is quick- can be done in half a day.
