Residential Wind Turbine Cost: A Comprehensive Guide

The cost of residential wind turbines can vary significantly depending on the power capacity, height of the tower, and equipment purchased. According to the American Wind Energy Association (AWEA), small wind turbines cost between $3,000 to $5,000 for every kilowatt of power capacity. Most homeowners using a wind turbine as their primary source of electricity install between 5 to 15 kW of wind power capacity, meaning they can expect to pay between $15,000 and $75,000 for their small wind turbine project. These numbers do not include any federal or state incentives.

Factors Affecting Residential Wind Turbine Cost

Power Capacity

The power capacity of a residential wind turbine is a crucial factor that determines the overall cost. Larger turbines with higher power capacities (e.g., 15 kW) will generally cost more than smaller turbines (e.g., 5 kW). According to the NREL, the total installed project CapEx for a representative residential distributed wind project is $5,675/kW.

Tower Height

The height of the wind turbine tower is another significant factor that affects the cost. Taller towers (e.g., 80-100 feet) can capture stronger and more consistent winds, but they also require more materials and specialized installation, leading to higher overall costs. The NREL estimates the tower and foundation costs to be around $1,500/kW for a residential wind project.

Equipment and Components

The specific equipment and components included in the wind turbine system can also impact the cost. These may include the turbine itself, charge controllers, poles/towers, batteries, cables, and other balance-of-system (BOS) components. The turbine CapEx typically accounts for 60-70% of the total installed cost, while the BOS CapEx makes up the remaining 30-40%.

Geographical Location

The cost of residential wind turbines can also vary depending on the geographical location. Regions with higher labor and material costs, as well as more stringent permitting and regulatory requirements, may experience higher overall project costs.

Economies of Scale

The cost of wind energy has been decreasing over time due to advances in technology and economies of scale. A detailed bottom-up analysis of innovation drivers found that changes in materials, labor, legal, and financial costs contributed over 30% to the cost reduction of wind turbines.

Comparing Residential Wind Turbine Costs

When comparing different residential wind turbine products, it’s important to consider the following factors:

Factor Consideration
Price The upfront cost of the wind turbine system, including all necessary components.
Design The turbine’s physical design, including blade size, generator type, and overall efficiency.
Power Capacity The maximum power output of the wind turbine, typically measured in kilowatts (kW).
Equipment Offerings Additional components included in the purchase, such as charge controllers, poles/towers, batteries, or cables.

Among similarly-sized wind turbines, price differences are largely due to the additional components included in the purchase.

Incentives and Financing

It’s important to note that the cost of residential wind turbines can be offset by various federal and state incentives, such as tax credits, rebates, and net metering programs. These incentives can significantly reduce the overall cost of the system, making it more affordable for homeowners.

Additionally, there are financing options available, such as loans, leases, and power purchase agreements (PPAs), which can help homeowners spread the upfront cost over time.


In summary, the cost of residential wind turbines can range from $15,000 to $75,000 or more, depending on the power capacity, tower height, and equipment purchased. However, it’s important to consider long-term wind speed data, potential incentives, and the overall value of the system in terms of energy savings and environmental benefits.
