Easy to install with 2 people. Great price. You need to get the tower kit separately. Will not power an entire house
 
Review Date: August 17, 2009
Reviewer: Citizen John, USA
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. Still, you can't beat this price for the Sunforce 44447, a wind turbine that will last a long time no matter the weather and give you an early breakeven point.

To determine whether it was a good idea to invest in wind power, I had to first make sure the location has enough wind. It's recommended that you have at least a 9 mph average wind speed at your house, and there are websites where you can check this. You have to have a radius of about 250 feet to accommodate your tower and make sure there aren't any laws against your putting up a tower. Regulations can be a little complicated, for example some states require easement rights to inspect your windmill (turbine!) whenever they want.

It's also a great idea to check with your utility company to find out if their policy is to connect a renewable energy system to the electrical grid, and they vary a lot in this regard. I am looking forward to the day when we get a federal law that requires power companies to buy excess renewable energy under conditions where it is a public good. The more of us that get wind turbines, the stronger our case will be, so I love to see those wind turbines go up. Until then one has to think more about battery storage and letting the system shut down once the batteries are fully charged in most states. If your utility company doesn't have a dedicated individual to deal with grid-connection requests, you can try contacting the state utility consumer advocate group or the state energy authority.

You still need to get the tower kit to mount the turbine. This is the one to get for this turbine: Sunforce 44455 Wind Generator 30' Tower Kit


Some things to do before buying
 
Review Date: April 21, 2010
Reviewer: Michael A. Duvernois, Minneapolis, MN United States
(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 found more infomation about it. Then bought it.
 
Review Date: June 12, 2009
Reviewer: HillBilly, NY
I have one of these and the reason I purchased it was after finding all the additional details at http://www.searchgeek.com 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.

Excellent
 
Review Date: April 18, 2009
Reviewer: David Stebbins,
If you're considering using the wind to generate electricity for your home, this book is probably the best you'll find to help you choose the right machine. More importantly, it may help you decide wind energy is not a viable option.
The author, Dan Chiras, has a gift. It's not in being inventive, or doing original work. Rather, it's his ability to distill and organize massive amounts of information and make it understandable.
He covers the pros and cons of wind energy. His co-authors, Mick Sagrillo and Ian Woofenden, are truly small scale wind energy icons. They use wind energy to power their own homes, and have written extensively about the subject, primarily in Home Power magazine. Sagrillo's article, "Apples & Oranges, Choosing a Home Sized Wind Generator" (Home Power #90, Aug/Sept 2002) is arguably the best 16 pages ever written about small scale wind. However, because all three authors love wind energy, the pros generally outweigh the cons when it comes to choosing wind as an energy source.
The book is divided into 9 parts:
Understanding Wind and Wind Energy, covering friction and turbulence, and the concept of wind as cube: double the wind speed, and get eight times the energy.
Wind Energy Systems. Grid-tie versus off-grid.
Wind Site Assessment. Besides determining the wind potential of your site, a lot of emphasis, correctly, is on home energy conservation.
A Primer on Wind Generators includes the importance of "swept area" as being the most reliable indicator of generator output.
Towers and Tower Installation. There are three kinds of towers. A towers cost may exceed that of the generator.
Understanding Batteries. This has nothing to do with wind generators, but for those considering living off-grid, this chapter is important.
Inverters. If you're going to be tied to the grid you've got to have one. Covers the various types.
Maintaining a Wind-Electric System. Not for the faint of heart. You may decide wind is not for you after reading this chapter.
Final Considerations: Zoning, Permits, Covenants, Utility Companies, Insurance and Buying a System.
I've lived off-grid with a hybrid wind/solar system for nine years. I'm on my second wind generator. I wish this book had been available when I was building my system. The only comparable book available on small scale wind is Paul Gipe's, "Wind Power." It is also excellent, but is more technical, and for me, was less accessible.
For anyone interested in small scale wind energy, "Power From the Wind" is probably the best single source of information you'll find.
