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.
H5 (R9000) 5kW horizontal axis wind turbine
Our global market leading small wind turbine boasts an impressive power rating of 5kW with low environmental noise and visual impact.
With the capacity to start generating energy from much lower wind speeds and the ability to maintain performance as wind speed increases, the H5 is one of the most efficient small wind turbines available.
The H5 has been engineered with robustness, high reliability and low maintenance in mind, with the only wearing parts being the bearings. Its reliability is backed by millions of operating hours in the field, where its outstanding durability and minimal maintenance has been tried and tested by more than 2500 homes, farms and businesses worldwide.
