Revolutionary elegant design with the option of tower or roof mounting. The original motive for this design was to produce a turbine suitable for urban environments where wind speeds are low and constantly shift direction. This inspiring design could even tackle arguments opposing wind energy due to the 'ugliness' of wind turbines.
It can be installed on the ground on a 15m mast or on a roof on a 3m or 6m mast. The 6m mast is recommended due to the increase in wind speeds the higher the turbine above the building. The turbine has a blade of diameter of 5m and a rotor diameter of 3.1m.
Wind turbines
Swept area
The QR5 has a blade diameter of 3.10 metres. This is all important when comparing wind turbines, since it directly relates to the amount of passing wind energy the turbine blades can intercept.
QR5 power output curve
The graph below shows the power produced (in watts) for the QR5 at different wind speeds, based on data supplied by the manufacturer.
Whilst the above graph gives an indication of the instantaneous power you might expect from the
QR5 turbine, working out annual power production is more complex.
The only way to know for sure is by measuring your wind speeds using an anemometer for a period of time and then working out what a generator like this would produce.
Luckily, we've invented something that makes this easy, called the
Power Predictor!
Power output
Note that active power throttling begins above 14 m/s, with auto shutdown in at speeds above 16 m/s.
Cost
Typically in the range of £35-40,000 for complete installation. The package includes a generator, anemometer, accelerometer and peak power tracking hardware as well as all electrical and mechanical controls and stand alone tower and anchors.
