Cost: Home wind generators range from $300 to $75,000 installed. Factors: Cost is influenced by turbine type, size, wind speed, installation location, labor, maintenance, and tax credits. Q1: What factors influence the cost of a home wind generator?Dramatic Cost Range: Wind turbine costs span from $700 for small residential units to over $20 million for offshore turbines, with total project costs varying from $10,000 to $4,000+ per kW installed depending on scale and location. Total installed costs for utility-scale onshore wind have continued to decline, but they are beginning to stabilize as. The cost of a wind turbine depends largely on its size and capacity. Small turbines, under 100 kilowatts, typically cost around $3,000 to $8,000 per kilowatt of power capacity.
