Wind Energy Calculators
Free wind energy calculators: turbine power output, annual energy production, payback period, capacity factor, and wind vs solar tools.
Wind Turbine Annual Energy Production (AEP) Calculator
Estimate annual kWh from a wind turbine using rated power, capacity factor, and operating hours. Includes site quality and array losses.
Wind Shear Hub Height Correction Calculator
Correct measured wind speed to turbine hub height using the wind shear power law. Pick terrain class and measurement height for an accurate hub speed.
Wind Turbine Capacity Factor Calculator
Calculate wind turbine capacity factor from rated power and annual energy. Compare your turbine output to onshore and offshore industry averages.
Wind Turbine Tower Height Wind Speed Boost Calculator
Calculate wind speed boost from raising a turbine tower. Use the wind shear power law to compare hub-height speeds at 30, 50, 80, or 100 feet up.
Air Density Calculator
Calculate air density from temperature, pressure, and altitude. Used for wind turbine power corrections, aviation, and aerodynamics.
Wind Speed Unit Converter
Convert wind speed between m/s, km/h, mph, knots, and Beaufort scale. Includes Beaufort description and wind turbine cut-in reference.
Wind Turbine Payback Period Calculator
Calculate how long a home wind turbine takes to pay for itself. Factor in installation cost, annual output, and electricity savings.
Wind Turbine Power Output Calculator
Calculate how much power a wind turbine produces at a given wind speed. Estimate annual energy output from rotor diameter and average wind speed.
Wind vs Solar Energy Comparison Calculator
Compare annual energy output and cost from wind and solar at your location. Find which renewable energy source suits your site better.
