𖣘 Wind Energy Calculator

Estimate turbine power and annual energy from wind speed, rotor size, Cp, and losses.

Turbine B - Inputs

Wind Speed (m/s)

Air Density ρ (kg/m³) ?

Rotor Diameter & Area (keep in sync)

Diameter (m)

Swept Area (m²)

Power Coefficient Cp: 0.40 Range: 0.20 – 0.50 (Betz limit ≈ 0.59)

System Losses (%)

Annual Operation

Hours per Year

Use Capacity Factor instead
