use the wind

This is a highly efficient wind turbine, suitable for domestic locations with typically half an acre of land within a semi-rural environment. This will provide sufficient energy for a normal single domestic dwelling, enabling much of the purchased electricity to be replaced by this green energy production. With over 700 of these turbines in existence they have shown their outstanding durability qualities, in any location. The installation of this turbine is simple not requiring a crane for erection.

The Evance R9000 small wind turbine is the result of years of dedicated research and development, based on engineering experience of designing big wind turbines.

Specifically designed to capture more energy at lower wind speeds makes the R9000 one of the most efficient 5kW turbines available.

The Evance R9000 includes state-of-the-art technologies, such as the patented blade pitch system and a highly efficient generator, which converts up to 96% of the energy captured into electricity in on and off grid applications.

The Evance R9000 belongs to the ‘next generation’ of small wind turbines, offering class leading quality, performance and reliability.

The efficient and reliable R9000 is already enabling homeowners, farmers and businesses around the World reduce energy bills and carbon footprint.
