How Much Does A Residential Wind Turbine Cost?
For residential use, you will want a wind turbine system with an output of 2 – 10 kilowatts per hour, depending on the size and energy efficiency of your home, and your family’s needs. Your bottom line costs will include: turbine, tower, inverter, wiring, foundation, shipping, installation, zoning and permit fees, and more.
Urban And Suburban Wind Turbine System (turbine only, tower and installation not included) - $6,500 to $15,500
The Helix Wind Savonious is a revolutionary design that can be used in urban and suburban settings because of its very small footprint and ease of installation. Sizes range from 2–5 kilowatt systems. The turbine can be mounted on a 15–35 foot tower, or can be roof-mounted two feet above roof line. The scoop-shaped rotor is only 6 x 4 feet, has a quieter action, and is more bird-friendly, neighbor-friendly, and zoning commission-friendly than traditional systems.
Suburban Wind Turbine System (self-installed) - $15,000
The Skystream 3.7 is a new wind turbine system designed specifically for suburban homeowners looking for affordable solutions with a small “footprint,” that they can install themselves. Towers range in the 30- to 40-foot range, and rotor diameter is 12 feet. This system operates at wind speeds as low as 9mph and can generate between 1.8 and 2.4 kilowatts – enough to satisfy 50% to 100% of the needs of an average, energy efficient home. The system pays for itself in 5 to 15 years.
Suburban And Rural Wind Turbine System (tower, wiring, fees and installation included before rebates and other incentives) - $22,000 to $55,000
Larger systems range from 4 to 8 kilowatts with towers up to 100 feet tall. These will generally produce enough electricity to completely satisfy the needs of most American homes with average energy efficiency.
A 10 Kilowatt System - $80,000 to $125,000
This is a very substantial wind turbine system requiring a 90- to 120-foot tower, large-size turbine, special zoning and town permits to erect the structure, and hefty shipping and installation costs. Once up and running, this system will produce enough energy to completely satisfy the needs of a very large house, or possibly a business or large school. This price includes professional installation, before rebates and incentives.
How much will you save?
Of course, it all depends. How much you save depends on the energy efficiency of your home and your local electricity rates. However, depending on your wind turbine system size, wind quality, permit and energy costs, and turbine performance, payback periods for small wind systems range from 6 to 15 years. Larger systems (10 kilowatt) can take 15 to 30 years to make up your initial costs.
