When should the turbine be shut down?
It is always best to use a weather forecast to predict wind speeds and shutdown the turbine
in anticipation rather than in reaction to high winds.
www.xcweather.co.uk is a good place for
this information.
It is recommended that the turbine is parked in wind speeds above force 6 Beaufort (12 m/s,
28 mph). At these average wind speeds, gusts are likely to be damaging. If wind speeds are
forecast above force 8 (18 m/s, 40 mph) then, if possible, the turbine should be taken down.
