Whisper, a name with more than 10 years of experience in the field, has been re-engineered and launched under the Southwest Windpower family of wind turbines.

The Whisper has an all-new look featuring a cast aluminum frame and smooth, quiet operation of the patented "angle-governor" furling design.

Whisper 500 - The most powerful wind turbine in our lineup

The 3000-watt rated 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. The 500 has been redesigned, incorporating a stronger, larger yaw shaft, new blade stabilizer straps and a third spindle bearing for increased reliability.

The 500 features a handmade 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 500 is an excellent machine for village power projects, farms, ranches, back-up power and remote homes with large energy demands.
