H11 11kW horizontal axis wind turbine
The Britwind H11 is a state-of-the-art small wind turbine, designed by the same team that developed the market leading Britwind R9000 (H5) wind turbine.
The whole concept of the Britwind H11 has been engineered with robustness, high reliability and low maintenance in mind, with minimal wearing parts and no gearbox. The turbine also has a class leading performance to installed cost ratio.
The 11kW turbine is designed to have exceptional performance at lower wind speeds.
For higher wind speed areas, the H15 will be more suitable.
