How big is a 10 kW wind turbine?
Wind turbines are devices that collect wind energy and convert it into electricity. They are typically installed on tall towers and are electrically compatible with the utility. The electricity generated by the turbine is fed into the household wiring through the breaker panel.
In a residential setting, the home is served by both the wind turbine and the utility. If the wind speed is below 7 mph, the turbine does not produce any electricity and all the energy needed is bought from the utility. As the wind speed increases, the turbine output also increases, and the amount of energy purchased from the utility decreases accordingly. When the turbine produces more electricity than the house needs, the excess electricity is sold back to the utility. This entire process is automated and does not require the use of batteries.
A standard residential wind system can lower the utility bill by 50-100%. Homeowners with total electric homes and Bergey turbines often have monthly utility bills of $15-20 for most of the year. In areas where less air conditioning is used, the bills can be even lower throughout the year.
The size of the wind turbine needed for a home depends on the average wind speed in the area and the amount of electricity used. Typically, homes use 1000-2000 kilowatt-hours of electricity per month, which requires a wind turbine rated in the range of 5-15 kilowatts. The BWC EXCEL 10, a 10 kW unit with a rotor diameter of 23 feet, is the most popular residential unit in the US. In 2019, a new 15 kW turbine with advanced features and double the energy production capacity was introduced. This new turbine, called the Excel 15, can provide all the energy needed for a total electric home, including heating and an electric car, if there is a moderately good wind resource.
Wind turbines are not suitable for urban or small-lot suburban homes. A property size of at least two acres is recommended, unless the closest neighbors are supportive. The economics of a wind system depend on the average wind speed, availability of rebates or tax credits, and the cost of electricity. A minimum average wind speed of 10 mph and an electricity cost of $0.12 per kilowatt-hour or more are generally recommended. Wind resource maps for the entire US are available to determine the wind resource in a specific area.
Installing a wind turbine at home helps the environment by producing clean energy and offsetting the pollution that would have been generated by the utility company. Over its 30-year lifespan, a BWC EXCEL 10 or Excel 15 can offset approximately 12-3 tons of air pollutants and 200-500 tons of greenhouse gases.
