"DO I HAVE A GOOD SITE FOR WIND POWER?"
Wind powered battery charging systems can be cost-effective if the average wind speed is nine miles per hour (mph) or more at the location of the wind generator. If you are using wind in combination with photovoltaic power, it may be cost effective if good wind is available only during part of the year. When the wind speed doubles, the power delivered is eight times as great . Most wind generators are designed to deliver maximum power at a wind speed of 30 mph. At 15 mph, they will deliver about 1/8 their rated power. A wind generator should be mounted at least 20 feet higher than any obstruction within 300 feet to avoid turbulence. The power output of a wind generator will decrease roughly 3% for every 1000 feet of elevation.

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.

 
Wind Speed (MPH) Wind Effect

0-1

Smoke rises vertically

2-3

 Direction of wind shown by smoke drift but not by wind vanes.

4-7

 Wind felt on face; leaves rustle; ordinary wind vane move

8-12

 Leaves and twigs in constant motion; wind extends a light flag

13-18

Raises dust, loose paper; small branches are moved

19-24

Trees in leaf begin to sway; crested wavelets form on water

25-31

 Large branches in motion; whistling heard in power lines

Towers

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. Freestanding towers, guyed towers or guyed poles may be used with wind generators. Wind generators can be mounted on freestanding towers designed for antennas. They require a large, engineered concrete base for support, but since they do not require guy wires, they can be installed in the smallest space. Guyed steel truss towers, also designed for antenna mounting, are less costly and require a large area for guy wire placement. A tilt-up pole tower is 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 tubing can be bought locally to save freight.

Kestrel 1000 Pocket Wind Meter

The Kestrel 1000 measures instantaneous, maximum and average wind speeds. Measurement unit options are knots, meters per second, kilometers per hour, miles per hour, feet per minute and Beaufort. Just hold it up to measure wind speed. Large, easy-to-read liquid crystal display with +/-3% accuracy. Measure down to 0.3 m/s. Impeller and protective housing pop out for easy and inexpensive replacement. Includes slip-on hard case that protects the impeller, buttons and display from damage in your pocket or toolbox. It is waterproof and it floats. The replaceable battery provides 400 hours of use.

One year warranty.

    WHISPER WIND GENERATORS

    The Whisper 100 and 200 are shipped in a 24 volt configuration, but can easily be changed to 12, 36, or 48 volts by the installer. The included controller is adjustable for use with 12, 24, 36 and 48 volt battery systems and the voltage can be adjusted for any battery type. The control can be set to to stop the blade from spinning when the battery is fully charged, avoiding wear when power is not needed. The control has a "Selectable Silent Mode" setting that allows the user to select any specific period to automatically turn the wind turbine on or off.

    An optional digital display may be added to the control to display total kilowatt hours, peak amps, peak and average wind speed to measure wind speed, optional wind speed sensor must be ordered.
    5 Year Warranty
     

    Whisper 100 Wind Generator

    The Whisper 100 is designed to operate in a site with wind speed averages  of 12 mph and greater. It delivers 900 watts peak power at 28 mph (12.5 m/s). It can provide 100+ kWh per month, 3.4 kWh per day, in a 12 mph average wind speed location. The 100, with its 7 ft. (2.1m) rotor diameter and 40 sq. ft. swept area, is rugged enough for extreme environments. The 3-blade design lasts longer and is more stable in turbulent wind. The Marine version is sealed and powder-coated for use in coastal and nautical environments.

    Whisper 200 Wind Generator

    The Whisper 200 is designed for the user who lives in low to moderate wind speed averages (less than 12 mph). The bigger brother to the 100, the 200 features a 10 ft (3.1m) 3-blade rotor diameter and an 80 sq. ft. swept area that provides the user with greater output at low wind speed averages. The 200 has twice the swept blade area, providing double the potential energy, compared to the 100. It delivers 1000 watts peak power at 28 mph (12.5 m/s), but has a higher output than the 100 at lower windspeeds.

    Whisper 500 Wind Generator

    The Whisper 500 is a 3000-watt rated turbine that will deliver in excess of 500 KWH per month in a 12 mph wind. This machine has a 14-foot, 2 blade rotor providing 500 sq. ft. of swept area. It 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. The Whisper 500 comes in two boxes and is shipped truck freight.The Whisper 500 is available in a 24 volt and a 48 volt version.

    The Skystream 3.7 is a new generation of residential wind generator that hooks up to your home to reduce or eliminate your monthly electrical bill. It’s the first all-inclusive UL Listed wind generator (with controls and inverter built in) designed to provide quiet, clean electricity in very low winds. The Skystream is ideal for residential homes and small businesses. Skystream connects directly to your home. When the wind is blowing, your home is powered (in part) by Skystream; when it’s not, your home is seamlessly powered by your utility, as usual. During periods of strong winds, Skystream can actually produce excess electricity. Depending on your utility, your meter will spin backwards – giving you credit for a later date. Estimated energy production is 400 kWh per month in a 12 mph wind.

    If your site fits the following criteria, Southwest Windpower’s Skystream 3.7 may work for you:

    • At least 10 mph average wind speed (best results at 12 mph or more)
    • Your property is at least a half acre and has unobstructed views
    • The local zoning allows a structure that is at least 42' tall
    • Your utility has an existing interconnection agreement for homeowners

    With a rated capacity of 1.8 kW, Skystream can provide anywhere from 40 to 100 percent of the total energy needs a of a household or small business. Its sleek, distinctive 12-foot diameter swept-wing blades and elegant form make Skystream an attractive addition to any home. With a guyless tower, Skystream blends in like a neighborhood street lamp. And because it operates at a low rpm, Skystream is as quiet as the trees blowing in the wind.

    Skystream can be used in off-grid battery charging applications that include a bidirectional inverter such as a Xantrex SW or SW Plus or OutBack FX or VFX inverter.

    The Skystream is connected to a breaker in the load center powered by the inverter. For this type of installation, the wireless remote battery sensor must be installed to stop the Skystream when the batteries are fully charged.

    An optional two-way remote display unit lets you control your Skystream from up to 1000 feet (300 meters) away. You can also monitor performance and download energy performance data to your personal computer via USB converter.

    5-year limited warranty.
