How to Use This Calculator
- Enter the rotor diameter of the selected wind turbine.
- Set the prevailing wind direction to determine the dominant spacing axis.
- Input the desired array size (number of turbines in row and column).
- Review the recommended row and column spacing in rotor diameters (typically 5–7D and 8–10D respectively).
- Optimize spacing to balance wake losses against land use using an energy yield model.
How the result changes with Rotor Diameter
| Rotor Diameter | Maximum Turbines | Total Capacity |
|---|---|---|
| 38 | 500 | 1,500 MW |
| 83 | 104 | 312 MW |
| 137 | 38 | 114 MW |
| 182 | 21 | 63 MW |
What each input means
- Rotor Diameter
- Diameter of the turbine rotor.
- Downwind Spacing
- Spacing in the prevailing wind direction as a multiple of rotor diameter.
- Crosswind Spacing
- Spacing perpendicular to the wind as a multiple of rotor diameter.
- Farm Area
- Total available land area in acres.
- Turbine Rated Power
- Rated power of each turbine.
