At a particular location, the wind speed will vary about an annual mean value. The expected energy yields for the Vestas V27 at various annual wind speeds (AMWS) is shown below:

AMWS m/s Annual MWh Daily kWh
4 128 351
5 255 699
6 411 1126
7 575 1575
8 734 2011
9 878 2405

Note: The annual electricity consumption of a medium size home is in the region of 4- 6MWh or 11-16 kWh per day. At 6 m/s wind speed the Vestas V27 can provide the annual energy needs for 100 homes.
