This wind turbine power reference table shows the power output for a range of blade radius values, assuming a wind speed of 8 m/s and a power coefficient (cp) of 0.4. Every figure is computed with the same engine that powers our Wind Turbine Power Calculator, so the numbers are exact.
| Blade radius | Power output |
|---|---|
| 0.5 m | 98.5 |
| 1 m | 394.1 |
| 1.5 m | 886.7 |
| 2 m | 1,576.3 |
| 3 m | 3,546.7 |
| 4 m | 6,305.3 |
| 6 m | 14,186.9 |
| 10 m | 39,408.1 |
| 14 m | 77,240.0 |
| 20 m | 157,632.6 |
How to use this table
Find the row closest to your blade radius and read across to the power output. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Wind Turbine Power Calculator for a precise answer.
