The 25Kw Kh2.0 twin turbine will generate an annual yield of 43,800Kw which equates to £11,694.60 per year based on UK Carbon Trust data and new feed in tariffs commencing April 2010.

Each turbine is a mere 3m in diameter, making it 5 times more powerful than an equivalent sized open rotor turbine. The KH2.0 is setting a new benchmark within the small wind turbine industry, with engineering excellence at the core of its’ success.

Specmanship between turbine manufacturers encourages them to present power output at the most favourable conditions. But what matters is not the peak power achieved in a wind tunnel, but the actual annual yield.

By deploying a diffuser, the Kh2.0 turbine can deal with turbulent conditions better than an open rotor as it acts nearly instantaneously to align modest changes in wind direction – well beyond the turbines slewing speed. The smaller blade diameter reduces the difference in wind speed from top to bottom. The augmented wind speed through the duct promotes an earlier start up. The autopitch has various operational benefits as discussed, but in particular allows the turbine to operate more efficiently in rapidly fluctuating wind speeds.

All of these factors enable the Kh2.0 turbine to out perform conventional turbines with equivalent peak operating power in the real world of less than ideal conditions.
