Product Description

The Sunforce 44447 Whisper 100 900 Watt Wind Generator uses wind to generate power and run your appliances and electronics. Constructed from lightweight, weatherproof cast aluminum, this generator is also a great choice for powering pumps or charging batteries for large power demands. With a maximum power up to 900 watts or 60 amps, this device features a fully integrated regulator that automatically shuts down when the batteries are completely charged. The 44447 is virtually maintenance free with only three moving parts, and the carbon fiber composite blades ensure low wind noise while the double-sealed ball bearings guarantees a smooth, clean charge. Assembly is required, but this generator installs easily and mounts to any sturdy pole, building, or the Sunforce 44455 Wind Generator 30-Foot Tower Kit.

I invested in this Sunforce 44447 900W Wind Turbine for a small house in a wind zone. With some help I installed the windmill (I was corrected several times - they're called "wind turbines") - it was very simple. Installing the tower kit is where the time is, because sliding on the turbine and installing the blades is easy. This is a quiet windmill. This 74 pound turbine has only 3 moving parts so it is unlikely to break down. It came with a 5-year warranty. It starts up at about 7.5 mph wind speed and it's working fine! You should get the Sunforce Tower Kit with it, and it will be 30 to 33 feet high. You also need batteries to store the power.

The current price at the time of this review, about $2,200 is a better than what I paid to own it. I paid just over $2,600 early in the year and that was the very best price available at the time, without free shipping and from H.D. Thus the current price is excellent, probably the best price compared to buying it from another vendor, and compares favorably versus similar Gamesa, Enercon and GE Energy turbines because I checked. But make sure you get the manufacturer's 5-year warranty.

With a maximum power of 900 Watts at best, this turbine is not going to be adequate to power an entire big house. It is recommended for a "cottage" or "cabin." But it's great backup power nevertheless, and as long as there is a wind speed average of 12 mph or better, there's no worry about it paying for itself. This experience made me more confident about wind turbines and I'm thinking next time to go with the Sunforce 44490 if that price hits my sweet spot. That one is more expensive but gets higher output at lower wind speeds and delivers twice the output of this one.

(This is a great turbine for the correct wind conditions. Well-built and very inexpensive for what you get.)

There are good reviews here and elsewhere, but I wanted to add a couple of do-before-buying recommendations:

- Don't rely on a simple windmap of your area of the country
- Measure it. There are many folks who have datalogging anemometers available for loan/rent on a tall pole.
- Put up a pole the height you're thinking of, and measure the wind speeds for (ideally) a month in the summer and in the winter.
- Consider going another ten feet higher in elevation. Most of the small wind turbines I've seen in the field have been mounted lower than optimal for the winds. The price of a taller tower is small compared to the turbine operating less efficiently.
- Then compare actual wind speeds with the power output vs. wind speed curves
- Get a permit if it's required!

I have one of these and the reason I purchased it was after finding all the additional details at [...] it helped me decide and I love it. It is great having free electricity. All my neighbours think it is great but someone did call the town and they said I need a permit. We will see.
