Why buy a small wind system?

A Bergey wind turbine is a smart investment that will lower your monthly expenses, increase your net worth, and help support American manufacturing jobs. At the same time it will help clean the air, slow climate change, and move us towards energy independence.

You will also enjoy watching your utility meter turn backwards and the lively interaction between the wind and your Bergey turbine. Finally, it will totally change your view of wind – you will start appreciating windy days.

It's like buying vs. renting a house

Over the next 10 years a typical homeowner or small business will pay $18,000 to over $50,000 in electric bills, at rates that will often increase faster than inflation. When you choose a Bergey wind system you take the same monthly expenses and invest it in a tangible asset. Once your Bergey turbine is paid off, you will enjoy more money in your pocket for the next 20-40 years.

A Bergey wind turbine is an excellent investment. It will typically provide a rate of return of 6%-25%, much better than traditional investments.

Tax Credits and rebates make it affordable.

Small wind turbines qualify for a 30% federal tax credit and, for businesses, accelerated depreciation. USDA grants are available for farmers, ranchers, and rural businesses. Many states offer additional incentives (see www.dsireusa.org).These incentives make owning a Bergey wind turbine surprisingly affordable.

Why a Bergey wind turbine?

Bergey Windpower is the oldest and most experienced manufacturer of residential-sized wind turbines in the world. Thirty years ago Bergey pioneered the radically simple “Bergey design” that has proven to provide the best reliability, performance, service life, and value of all the hundreds of competitive products that have come and gone in that time. With only three moving parts and no scheduled maintenance necessary, the Bergey 10 kW has compiled a service record that no other wind turbine can match. We back it up with the longest warranty in the industry.

There are now many new small wind products on the market. Though sometimes heavily promoted, these new entrants lack the track record that provides confidence as a sound investment. Over the years Bergey wind turbines have often replaced unsuccessful competitive products. The bottom line is that wind turbines are a big investment, and Bergey is the wise choice.

Bergey turbines are simple, but they also incorporate sophisticated technology that has been refined over more than a quarter-century. From its custom airfoil to its “super magnet” low speed alternator to its custom inverter, there’s no more advanced technology in the industry. The result is exceptional low wind speed performance, robust storm protection, and almost silent operation.

Finally, Bergey offers more tower options than any other small turbine manufacturer. We have Guyed-Lattice, Self-Supporting Lattice, Tubular Self-Supporting Lattice, and Guyed Tilt-Up Lattice towers in heights up to 140ft.

Bergeys are built on strong basics:

  • Simplicity - the only moving parts are the parts you see moving.
  • Reliability - developed in "Tornado Alley," proven in critical military applications, and backed by our exclusive 10-year warranty.
  • Performance - low start ip (5 mph), continuous in high winds, and extremely quiet.

Our technology makes it happen!

  • PowerFlex Blades – our exclusive “full length reinforcement” fiberglass blades are stronger than steel and the strongest in the industry.
  • BW-7 Airfoil – our custom designed airfoil (blade shape) is quieter and more efficient than the “catalog airfoils” others use.
  • Neo-10 Alternator – our custom designed very-low-speed “super magnet” alternator also serves as the blade mounting hub, integrating what are typically two separate assemblies.
  • AutoFurl Storm Protection – our uniquely simple passive, fully automatic, high wind protection is hurricane proven
  • Powersync II inverter – our custom designed third-generation power converter is UL-certified and extremely rugged.

Buying a Bergey Turbine.

The best candidates for a Bergey 10 kW wind turbine are those with a residential or commercial property of at least 3 acres, an electric bill averaging over $125 a month, and a wind resource of at least 10 mph. Each project is a little different so a site survey and quotation are necessary. The typical steps in buying a Bergey turbine are:

  • Contact EWS to set up a site survey
  • Provide EWS with total annual kWh used at your location
  • We will produce a wind resource report for your location
  • We will match a tower height and turbine to best meet your needs
  • EWS handles all building permits and utility commissioning
  • Both off grid and grid tie design
