A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.
