Here the time “between the years” was used to give the blades of the Antaris 5.5 kW with the repeller diameter D5.30 a serrated band.
The background was the attempt to minimize the repeller noise.
In addition, the winglets have been removed.
Both together then brought a significant reduction in the repeller noise.
Whether it is due to the winglets or the serrated band remains to be clarified, but congratulations on that.
Joy of the wind with Antaris wind turbines!
