How to Use This Calculator

Enter the turbine's rated power in kW and rotor diameter in meters.
Input the average wind speed at hub height.
Set the air density at the site.
Review the estimated annual energy output in MWh and capacity factor.
Adjust for array wake losses (typically 5–15%) when calculating farm-level output.
