Frequently Asked Questions
What is a realistic payback period for a small wind turbine?
At good sites (12+ mph average) and retail electricity rates of $0.15+/kWh, residential turbines typically pay back in 10-20 years after the federal ITC. Poor sites may never reach payback without incentives.
Grid-tied vs. off-grid - which is better economically?
Grid-tied systems are almost always more economical because they credit all generated energy and avoid the high cost of battery storage. Off-grid is only preferred where grid connection is impractical.
What maintenance is required?
Annual inspections plus blade replacement every 10-20 years. Budget $300-$800/year for a 10-20 kW system, increasing with age.
How do zoning and setbacks affect siting?
Most jurisdictions require setbacks of 1-1.5 times tower height from property lines. Residential areas may prohibit turbines. Verify local codes before purchasing equipment.
