Eco Evolution are resellers and installers of the Evance R9000 Wind Turbine in the Leinster region.

Evance, a leader in the manufacture of small wind turbines, is the first company to have completed the Mircogeneration Certification Scheme(MCS) Phase 2 requirements when the MCS Transition Arrangements document was issued on 28^th April 2010. The MCS gives consumers the guarantee that certified microgeneration products and the installers of those products have conformed to a rigorous set of standards.

Eco Evolution are  pleased to announce that the Evance R9000 5kW wind turbine has completed all tests and has been awarded full Microgeneration Certification Scheme (MCS) accreditation. This accreditation is a formal recognition of the durability, reliability, safety and overall performance of the R9000, which provides customers with confidence in the turbine, as well as entitlement to income from Feed-in Tariffs.

Evance Press Release  20th July 2010:

Evance, a leader in the manufacture of small wind turbines, is pleased to announce that its R9000 5kW wind turbine has completed all tests and awarded full Microgeneration Certification Scheme (MCS) accreditation.

The Evance R9000 Advanced Wind Turbine is the result of 10 years of dedicated research and development, and is based on the experience of designing utility scale turbines. Specifically designed to work with the wind to capture more energy at lower wind speeds, the R9000 is the most efficient 5kW turbine available, producing more energy a year than other 5kW, 6kW and even 10kW turbines. Combining patented state of the art technology and elegant design, the R9000 belongs to the ‘next generation’ of small wind turbines, offering class leading quality, performance and reliability.

The R9000 is manufactured in the UK at new purpose-built facilities near Loughborough. Using automotive experience, each one is assembled under strict quality control. Every R9000 undergoes final testing to ensure that it complies with Evance exacting standards.

Eco Evolution appointed official Evance resellers/installers for Leinster area. ReGen(NI) have licenced Eco Evolution as resellers of Evance wind turbines.
Evance is the commercial brand name of Iskra wind turbines. Eco Evolution covers the counties of Wexford, Kilkenny, Carlow, Wicklow, Laois, Kildare, Offaly & Dublin.

In November 2009 an Evance R9000 Windturbine was installed in Emyvale, Co. Monaghan under the SEAI(Sustainable Energy Association of Ireland)  Micro-Generation pilot scheme. This turbine was installed on a 12 meter tower and is a grid connect system. Joe was delighted with the install and  the performance of the turbine.

“The Evance R9000 is the latest variant of the long established 5kW small wind turbine from the UK manufacturer Iskra, recently re-branded as Evance.

The R9000 is the first turbine to be equipped with Reactive Pitch technology, a unique control concept developed and patented by Evance. Reactive Pitch guarantees that the blades will capture exactly the right amount of energy according to the wind speed and generator loading conditions.

At low to moderate wind speeds the Reactive Pitch mechanism captures the maximum energy possible from the wind by holding the blades with absolute precision at the maximum efficiency position.

At higher wind speeds, when the energy in the wind exceeds the maximum capacity of the generator, the R9000’s unique Reactive Pitch mechanism automatically pitches the blades. This regulates energy capture, rotor speed, and the loads experienced by the turbine structure. It will therefore capture the full 5kW power, and the reduction in stresses mean that the R9000 offers greater safety and survivability

The R9000 also has a patented high-efficiency generator which converts up to 96% of the energy captured from the wind into useful electricity. The generator is specifically designed for the R9000, and is integrated into the turbine’s rotor.

What all that means is that the Evance R9000 can capture more energy across the range of wind speeds, especially the lower and moderate speeds that are normally experienced on the majority of the mainland UK.
The combination of the advanced pitch control, which is much more effective than the Proven’s “coning” mechanism, and the more efficient generator enable the Evance R9000 to out perform the Proven WT6000 at lower to moderate wind speeds…”
