Yaw misalignment, when a rotor isn’t facing the wind with the optimal angle, is a common and well known issue on most wind turbines.
Even a small yaw misalignment can result in a significant decrease of about 1-5 % of the annual energy production of the wind turbine and increased loads on the wind turbine.

TRES Wind offer an up and down service where we use nacelle based LiDAR to detect and correct static yaw misalignment on all types of wind turbines.

ROI normally less than 2 years.
