NOTE:

Comparing wind turbines? In August 2009 for 5 months we monitored the wind speed at each turbine tower with identical anemometers at identical heights. These indicated that the Proven turbine is experiencing a much better wind resource from the South West quadrant than the Evance. This should influence your comparison of the out put figures figures. There may be as much as 40% more energy in the wind at the Proven site. The analysis was carried out by ISKRA who manufacture the Evance turbine see Details

Output by month in table below (kWh)

Nb: Both wind turbines have a hub height of 26m
