Evance Iskra R9000
Enlarge	"In the first year, the Iskra* generated almost 15Mwh of energy, far more than we expected. I wouldn’t mind having a whole field of them.”* William Barons owner of an Evance Iskra AT5-1 Small Wind Turbine in Devon. Efficient Wind Power from the Evance Iskra R9000 Wind Power Generator The Evance Iskra R9000 is probably the most sought after small wind turbine available. Being the "next generation" of small wind turbines, it fully integrates the very best of existing technologies with major new patented innovations. The result is an attractive turbine with uncompromising performance and excellent reliability. The 'Evance Iskra R9000’ is even quieter, more efficient and more robust than the highly popular Iskra AT5-1. It is also easier to install and service whilst retaining its good looks! Evance wind turbines are the most efficient, cost-effective small wind turbines available. Designed as nature intended, their turbines work with the wind to capture more energy at lower wind speeds. The result is quiet, more efficient operation. Their design goes beyond simple ergonomics to guarantee your turbine makes an elegant addition to any surroundings, rather than an eyesore. The Iskra R9000 is designed for schools, farms, rural homes and light commercial applications. Click 'More' below for details of the Evance Iskra R9000 The turbine is an evolution of the popular and reliable Iskra AT5-1 and has been developed over two years, including continuous monitoring and evaluation on Evance’s test sites, instrumented and measured according to IEC standards. There are a number of key features that differentiate the Iskra R9000 from other small wind turbines and give it class leading performance, efficiency and energy yield, these include: Blade Technology - Airborne erosion testing (blowing more than 1000 pounds of sand at 60 mph onto blades) to twice standards necessary for military use. Improvements in manufacturing process, to ensure highest quality standards. Noise reduction - Advanced generator design which virtually eliminates generator noise, whilst maintaining 96% efficiency. Aerodynamic improvements in aerofoil design reduces overall noise by 40 percent. The turbine has been measured at Lp 60m = 45dB(A). BWEA Reference Sound Level at 8m/s and 60m distance. Efficiency – The AT5-1 was already the most efficient turbine in its class and the Evance Iskra R9000 has increased that efficiency by four percent, increasing energy yield from 8700kWh to over 9000kWh on a site with AMWS of 5m/s. Five year warranty – Evance is so confident of the quality of the new turbine that it comes with a five year warranty as standard. This assurance is based on the combined knowledge of all Evance’s installers and two and half million operating hours, with 99 percent uptime. Designed to meet the IEC61400-2 international standard, all of the R9000’s parts are manufactured in composite stainless steel or coated to automotive standards. All installations are backed by a manufacturer trained and certified service network. Energy – The Iskra R9000 generates more energy than any other 5kW turbine on the market – 9.012 kWH with an annual mean wind speed of 5m/s (11mph), measured to IEC and BWEA standards. Styling – The turbine has been styled to blend in with the environment for low visual impact and to fit planning demands, and improve resistance to the impact of extreme climates. The new turbine retains the feel of the iconic AT5-1 tail vane styling, but with more advanced design. Certification – The Microgeneration Certification Scheme (MCS) is reviewing the turbine currently and as Evance has been measuring noise and energy yield to IEC standards for over two years it is confident that Certification will confirm its leading performance. Reactive Pitch - The turbine’s Reactive Pitch™ technology ensures that its aerofoils are perfectly positioned to the wind at all times. With no cut out wind speed the R9000 generates power from 2.5 m/s (5.6 mph). Braking - A patented ElectroBrake™, which has no moving parts, stops the turbine at any wind speed and has no connection from the top of the tower to the ground or any other systems. The watchdog function on the ElectroBrake™ provides failsafe backup. Download the Evance Iskra R9000 brochure.
