Monthly Energy

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.

The Whisper 100 is one of the quietest wind turbines ever tested by the National Renewable Energy Labs.

In addition to its patented smooth acting side furling design, the Whisper 100 has a number of new features that make it ideal for any new or existing photovoltaic system.

Whisper Controller

Unlike many other small wind systems, the Whisper 100 ships with a controller that includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged.

It installs in minutes and it protects both your wind turbine and battery. The Whisper Controller fits easily inside your battery room. Add the optional LCD display and you will instantly receive real time data on the performance of your Whisper 100.

The display can be mounted on the controller or up to 1000 feet (300 meters) away letting you know what is happening. You can even add an anemometer to your controller and now you can measure wind speed and compare it to the output to make sure you are getting the most from your Whisper 100.

Wind as easy to use as photovoltaic's

The Whisper 100 is designed for even the novice. This turbine installs in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines.

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 100 during these periods is essential to keep your batteries charged and your lights on.

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.

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.
