Wind Turbine ROI Calculator

Calculate energy production, savings, and return on investment for residential wind turbine installations

Wind Resource Assessment Required

Wind turbines require average wind speeds of at least 10 mph (Class 3 wind resource) to be economically viable. We recommend a professional wind assessment before installation.

📋 Critical Considerations for Wind Energy

•Professional Wind Assessment Required: One year of wind data at hub height is recommended before installation
•Zoning and Permits: Many areas have strict regulations on turbine height, setbacks, and noise. Check local ordinances first
•Maintenance: Wind turbines require regular maintenance including annual inspections, bearing lubrication, and blade checks
•Noise Considerations: Turbines produce noise that may affect neighbors. Minimum setback distances typically apply
•Grid Connection: Net metering policies vary by state. Verify your utility's interconnection requirements
•Wildlife Impact: Consider potential effects on birds and bats in your area
