Best for low to moderate wind - 7 mph (3 m/s) and above

The versatile Whisper 200 powers applications from remote homes to water pumping. Get the most out of the wind with a larger swept area. The Whisper 200’s 9-foot (2.7 m) blade has almost twice the swept area of the Whisper 100, yielding twice the energy. A high voltage model is available for transmission over long distances.

The Whisper 200 does produce more sound than it’s 100 counterpart, but it does produce almost twice the power.

In addition to its patented smooth acting side furling design, the Whisper 200 has a number of new features that make it ideal for any new or existing photovotaic system:

• A new four bearing spindle for a smoother operation and longer life
• An upgraded Yaw shaft that more efficiently delivers current to your batteries
• New bronze bushing and larger diameter furling pin for smoother furling action
• New castings that allow easy access to the stator for changing voltage

Spec Sheet

Wind as easy to use as photovoltaics

The Whisper 200 is designed for even the novice. The Whisper can be installed in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines. Now wind is as easy to use as photovoltaics.

Solar and wind work together

Solar and wind resources often compliment each other. Generally when it is sunny it is calm and when it is cloudy it is windy. This complimentary effect is even greater during seasonal changes. During the winter and spring when the sun is at its least exposure, the wind is at it highest. A Whisper 200 during these periods is essential to keep your batteries charged and your lights on.

Maximum output in any wind

 

Exclusive to the Whisper, the side-furling Angle-Governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. Unlike other wind turbines that lose as much as 80% of their output when furled, the Angle-Governor allows the Whisper to achieve maximum output in any wind.

Whisper Towers

Southwest Windpower offers tower kits that are easy and safe to install. Our kits don't require welding or machining – you just need to obtain pipe material and power wires. We sell anchors separately.
