The R9000 small wind turbine is the result of nearly 10 years of development and has been system engineered to ensure maximum energy yield and durability.
The Evance R9000 is an ideal wind turbine for schools, community organisations, small farms or crofts and domestic use.
Other rural businesses such as caravan parks and holiday homes have had real success with the Evance wind turbines. With now over 600 turbines installed and an unrivalled track record of reliability and generation.
Through specific design, the R9000 is able to capture more energy at lower wind speeds making it the most efficient 5kW turbine available. The turbine’s reliability is backed by millions of operating hours in the field.
The energy production of the Evance R9000 is affected by the average annual wind speed that it experiences. The chart below shows the estimated annual generation of the Evance R9000 wind turbine at varying annual mean wind speeds.
