H11
An 11kW wind turbine designed to give exceptional performance at lower wind speeds. Can produce 37,000-48,000kWh/yr depending on location. Click here to find out more.
H15 15kW horizontal axis wind turbine
The Britwind H15 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 H15 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 15kW turbine is designed for the windiest sites (over 7m/s AMWS at turbine hub height). For lower wind speed areas, the H11 will be more suitable.
