Measuring Wind Speed

You can use one of the measuring devices at the right to determine wind speed. The Kestrel wind speed indicator works like a speedometer, displaying current wind speed, but does not record available wind power over time. The Wind Watcher monitors historical data as well as wind speed so you can install it and let it record for several months to get an idea if your location is a cost effective site for a wind system.

If you measure wind speed at ground level, you can expect about 1.5 times the wind speed 30 feet up, which equates to about three times the power. At 120 feet above the ground, wind speed will be twice what is measured at ground level and power output will be more than twice the output at 30 feet. If you do not have a wind gauge, you can get a rough idea of wind speed from the table below.

We do not recommend mounting wind generators on roofs. Though it is possible with a wind generator of 500 watts or less output, it will be noisy though and should this be what works for you, we do offer Roof Mounts.

We also offer Marine Mounts which easily mount the Air X Marine,  Air Breeze Marine ,  Whisper 100 Marine  or Whisper 200 Marine to your boat.

If you have an recreational vehicle and want a convenient way to set up a wind generator when you are on the road, we offer a telescoping RV Mount.

Freestanding towers, guyed towers, guyed poles or mono poles may be used with wind generators. Wind generators can be mounted on freestanding towers designed for antennas. Mono poles require a large, engineered concrete base for support, but since they do not require guy wires, they can be installed in the smaller space.  We are happy to now offer AnemErgonics SMarT foundation kits which simplifies the  installing of a mono pole.  SMarT foundations are custom built to meet your job needs, so please call.

Guyed steel truss towers, also designed for antenna mounting, are less costly and require a large area for guy wire placement.

Tilt-up guyed wire pole towers are the most economical and the easiest to install. Wiring and mounting of the wind generator are done before the tower is erected. No climbing is necessary. Steel pipe or tubing can be bought locally to save freight. 

• The Air X and Air Breeze can be use 1-1/2 inch steel tubing or Schedule 40 steel pipe where the winds could exceed 90 miles per hour. 
• The Whisper 100 and 200 require 2-1/2 inch Schedule 40 steel pipe
• The Whisper 500 uses 5 inch Schedule 40 steel pipe
• The Skystream although are usually mounted on a tapering mono pole can also be mounted this way with a Whisper 500 conversion kit
