The paper presents a monitoring campaign over two commercial small size wind turbines located in the Savona Harbour (Northern Italy) characterized by comparable nominal power and having respectively vertical and horizontal axis. The efficiency of the two typologies is investigated: it turned out that the horizontal axis turbine suffered from high levels of ambient turbulence and needed to be secured by reducing the slowing-down wind velocity threshold, which in turn affected the shape of the real power curve with respect to the theoretical one. Therefore, the present test-case suggests that horizontal axis wind turbines can represent a more attractive solution for small size realizations.

Abstract
The paper presents a monitoring campaign over two commercial small size wind turbines located in the Savona Harbour (Northern Italy) characterized by comparable nominal power and having respectively vertical and horizontal axis. The efficiency of the two typologies is investigated: it turned out that the horizontal axis turbine suffered from high levels of ambient turbulence and needed to be secured by reducing the slowing-down wind velocity threshold, which in turn affected the shape of the real power curve with respect to the theoretical one. Therefore, the present test-case suggests that horizontal axis wind turbines can represent a more attractive solution for small size realizations.
