Whisper 100

Whisper 200

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.

Best for moderate to high wind 9 mph (4 m/s) and above

Whisper 100 provides dependable energy for remote homes, telecommunications sites and rural applications in moderate to extreme environments. Reliable operation by thousands of customers makes Whisper 100 the top selling small wind turbine in its class. Assuming a 12 mph (5.4 m/s) average wind, a Whisper 100 will produce 100 kWh per month.

Winter Spring Summer Fall

Whisper systems combine well with photovoltaic solar panels to balance out fluctuating solar and wind resources.

Generally, winter months provide more wind and less sunlight, while summer months provide more sunlight but less wind. A hybrid system using a Whisper wind generator provides year-round energy production.

Will Wind Work For You?

The most important factors in decid-ing whether a Whisper wind system is right for you are wind resources and proper siting. Ask yourself the following questions:

• DoIhaveenoughwind–atleast9mph (4 m/s) average?

• Dozoninglawsallowtheuseoftowers?

• DoIhaveenoughland–1/2acre(0.2 hectare) or more?

A properly sited Whisper wind generator must be placed 20 ft (6 m) above any surrounding object within a 250 ft (76 m) radius.
