The quietrevolution™ qr5 was designed in response to increasing demand for wind turbines that work well in the urban environment, where wind speeds are lower and wind directions change frequently.
The elegant helical (twisted) design of the qr5 ensures a robust performance even in turbulent winds. It is also responsible for virtually eliminating noise and vibration.
At five metres high and three metres in diameter, it is compact and easy to integrate, and with just one moving part, maintenance can be limited to an annual inspection.
Clients include major retailers, developers, government departments, schools and universities.

For a prediction on what a qr5 turbine might generate at a particular site, please contact us to discuss. Alternatively read about wind assessment at our website. The minimum recommended average wind speed (AMWS) for a qr5 is 5.5m/s.
The energy output will vary according to the wind speed but is likely to up to 7,500kWh per annum depending on location.
According to the government building regulations, distributed generation in the UK will reduce CO2 emmisions by 0.568kg of CO2 per kWh.
