After a 66 month test of one of our 10 kW units, Wisconsin Power & Light concluded that, “The turbines’ reliability could not be improved upon.” Our turbines are designed to last 30-50 years or more and they operate completely automatically.ĭo they make noise or interfere with TV reception? Our turbines have only 2 – 4 moving parts and do not require any regular maintenance. In very hilly or mountainous areas, however, it may be prudent to take wind data before purchasing a system to ensure that your site in not in a sheltered area.Īre wind turbines reliable, and what about maintenance?īergey Windpower sells more residential systems than anyone else because our turbines have proven to be the most reliable on the market. of Energy, 2Tier and AWS Scientific is sufficient to predict performance. For residential systems the cost of taking wind measurements is not justified in most situations. Over its nominal 30 year life a BWC EXCEL 10 or Excel 15 will offset approximately 1.2 – 3 tons of air pollutants and 200 – 500 tons of greenhouse gases.ĭon’t I have to take wind measurements for a year or more? Wind turbines produce no pollution and by using wind power you will be offsetting pollution that would have been generated by your utility company.

Will it help the environment if I install a wind turbine at my home? Residential wind turbines have been installed in all 50 states. and we can provide you with information on your wind resource and performance projections. We have wind resource maps for the entire U.S. As a general rule-of-thumb, we recommend that you have at least a 10 mph average wind speed and be paying 12¢/kilowatt-hour or more for electricity. The economics of a wind system are determined by the average wind speed in the area, the availability of rebates or tax credits, and the cost of electricity.
We recommend a property size of two acres or more unless your closest neighbors are supportive. If you have at least a moderately good wind resource, the new Excel 15 can provide all the energy needed for a total electric home (and allowing you to replace fuel oil or propane heating) and an electric car.Ī wind turbine is a relatively large device and it is not suitable for urban or small-lot suburban homes. In 2019, we introduced a new 15 kW turbine with advanced features and an energy production capacity over double that of our 10 kW. It has a rotor diameter of 23 feet and is typically installed on 80 or 100 foot towers. Our 10 kW unit, the BWC EXCEL 10, is the best-selling residential unit in the U.S. Depending upon the average wind speed in the area this will require a wind turbine rated in the range 5-15 kilowatts. Homes typically use 1,000-2,000 kilowatt-hours of electricity per month. In northern parts of the country, where less air conditioning is used, the bills can be very low year round. It is not uncommon for homeowners with total electric homes and Bergey turbines to have monthly utility bills of $15-$20 for most of the year. The wind turbine typically lowers your utility bill by 50-100%. There are no batteries in a standard residential wind system. When the turbine output is more than the house needs, the excess electricity is sold to the utility. As the wind speed increases the turbine output begins and increases and the amount of energy purchased from the utility is proportionately decreased. If the wind speed is below about 7 mph there will be no output from the wind turbine and all the needed energy is bought from the utility. The home is served simultaneously by the wind turbine and the utility.
The turbine output is then made electrically compatible with the utility and the output is fed into the household wiring at the breaker panel. The wind turbine, which is installed on top of a tall tower, collects wind energy and converts it into electricity. Small Wind Turbines for Homes & Businesses
