Product Description
GREEF Variable Pitch wind turbine
Why choose AH-5KW Wind turbine?
Using the world's leading mechanical centrifugal variable pitch technology, the average annual
power generation is 30% more.
★Excellent
Large initial blade angle (+9°), excellent acceleration performance, start at low wind speed of 2.5m/s;
★Efficiently
Below the rated wind speed, the wind turbine outputs efficiently;
★Stable
Above the rated wind speed, adjust the pitch angle so that the rotor speed is maintained near the rated speed and
the power output is stable.
Annual Energy Production
| Annual Wind Speed(m/s) | 3.5 | 4 | 4.5 | 5 | 5.5 | 6 | 6.5 | 7 |
| Production (kWH) | 2481 | 3744 | 5168 | 7298 | 8277 | 12120 | 13785 | 16980 |
