Proven 11 - FF Solar

Proven 11product sheetEstablished in Scotland in 1980 Proven Energy is an industry leadermanufacturing and supplying many hundreds of wind turbines everyyear. With an operational fleet spanning 60 countries and everycontinent Proven Energy’s high performance wind turbines accrue over30 million run hours annually.Inspiration, innovation and a commitment to development haveensured these wind turbines produce electricity in a variety of windregimes without the necessity to be stopped for self protection.Proven Energy has more Proven 11 windturbines installed across the world thanany other product. First installed in 1996,there are now over 2,000 Proven 11 windturbines globally.Proven Energy products stand out fromother small wind turbines because oftheir patented blade hinge design, whichallows the wind turbines to regulate theirspeed, optimising output. As the windgets stronger, the blades pitch and coneto reduce their aerodynamic efficiency.The wind turbines use a direct drivegenerator and therefore have no gearbox,resulting in higher reliability, reducednoise, lower servicing costs and noreduction in performance in cold weather.2000+Proven 11 wind turbines installedgloballyCommunity installation,Isle of EiggDomestic installation,ScotlandWind turbinetypeDown-wind, self regulating rotorDirect drive with permanent magnetgeneratorProven 11 product specificationsTower heightsand typesRated power 5.2kW Connections Grid connectBattery chargingRotordiameterRAE5.5m Cut-in speed 3.5m/s8,949kWh(based on 5m/s wind speed at hubheight)Cut-out speed- 9m, 11.6m and 15m tilt up monopoleswith gin poles- 9m and 15m hydraulic optionsavailable; 20m available in 2011- Lattice tower available in NorthAmericaNoneSpecifications are subject to change without notice Nov 2010www.provenenergy.com 01355 597 000 info@provenenergy.com
