One of the key driving principles in the Orenda design is mechanical simplicity, which in turn delivers greater reliability and ultimately, and crucially, maximum up-time throughout the lifetime of the turbine system. One of the most unreliable components in small scale wind turbines is the pitch control mechanism. It can often be the source of down-time and un-scheduled service calls, in much the same way as a gearbox. There is no doubt that in an ideal world pitch control (designed properly) will yield more energy from the wind, however, the most significant multiplier in any wind turbine’s long term output equation is up-time. For this reason we chose to deploy a fixed pitch rotor set in the Orenda Skye design to maximise up-time and thereby maximising output and financial returns for our customers.
