Abstract
A method for cleaning the blades of a wind turbine using precipitation. The method includes determining the presence or absence of precipitation. In response to the determination of the presence of precipitation, adjusting the rotor speed to increase the speed of the blades and/or adjusting the variable pitch drive to increase the pitch of the blades. The combination of the increased blade speed and/or the increase blade pitch and the presence of precipitation facilitate the removal of debris from the blades by the precipitation.
