Evance Launches the Iskra R9000 Advanced Turbine

The new 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. The Evance R9000 comes with a 5 year warranty.



Enjoy the benifits of the latest technoligies.
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 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 5.6 mph/2.5 m/s

• 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.

Grants
Currently, NIE have a top up grant of £2,500 to support the LCBP stream 1 grant also £2500, taking the total available at present for domestic installations of wind turbines in Northern Ireland to £5000.

Also announced that as from the 1st April 2009, NIE will pay double NIROCs (Renewable Obligation Certificates), ie 2 NIROCs for each mega-watt hour of eligible output. This equates to 7.6p per kWh for all electricity generated, even if you consume it yourself and is an incentive scheme to encourage investment in microgeneration. This is a highly attractive option for home owners of small wind turbines dramically reducing payback times. With energy prices set to rise year-on-year, your Evance wind turbine delivers savings from the word go. Not only will it help reduce C02 emissions, once it’s paid for itself it will provide free energy for the rest of its working life. You may also sell your access power to NIE at the current rate of 7.4p per kWh but the best savings are created by utilising the as much power as possible generated by your turbine thus reducing your electricty bill.

The robust construction means it can withstand the force of wind speeds greater than 130mph. And with a 20-year, low maintenance life span they are designed to go the distance.
Skystream 3.7
ReGen (ni) are very pleased to announce the imminent availability in the Ireland of the brand new Skystream 3.7 small wind turbine from Southwest Windpower. The Skystream 3.7 is specifically designed for grid-connected homes and small business use. The Skystream 3.7 offers a simple, all-in-one solution to harnessing wind energy on a residential scale.The total cost of a Skystream 3.7 and tower is approximately £9,000 (excluding foundations and civil work).

Different from all other technologies, Skystream 3.7 is the first all-inclusive wind generator with the controls and inverter built into the turbine.

The Skystream 3.7 is a down-wind (wind hits the blades on the downwind side of the tower) direct drive (gearless or no transmission) permanent magnet wind generator. Skystream 3.7 uses an innovative 3.7m rotor and produces approximately 300 kWh per month at a typical 5m/s AMWS site. In addition to the innovative technology, Southwest Windpower have invested heavily in tooling to reduce component cost. Doing so makes it possible to sell Skystream 3.7 at a very low price. Its full 1.8kW is achieved at around 10m/s with a maximum rotor speed of 325 RPM. Because of the exceptionally low RPM for such a size of turbine, the machine operates nearly silently.

The Skystream 3.7 is supplied with a 10m or 14m free-standing tower which look much like a standard street lighting pole.

A visually aesthetic shape played a key role in the design to show that a wind generator is not only a clean source of energy but pleasing to the eye.

Independently Tested
Due to the collaboration with NREL, the Skystream is probably the most tested new small wind turbine to ever enter the market. Shown below are the power curve and noise data as measured independently by NREL.



Installation
The Skystream 3.7 has been designed for ease of installation, which allows us to keep the total solution cost as low as possible. A complete installation (excluding foundations and civil work), can normally be done in a single day.
The foundation is a standard concrete base measuring 1.8m X 1.8m X 0.9m with the foundation bolts embedded into it.
A cable trench, 600mm deep, will need to be dug between the turbine and your electrical connection. This is used to hold the 240V mains cable that brings the power from the turbine to the property.

You may arrange to have the foundations and cable trench done yourself, or ReGen (ni) can take care of it for you to provide a complete turn key solution.

With the inverter built in to the turbine, the electrical installation is very straightforward and simply needs a spare connection into your existing mcb/fuse box.

Please note that the Skystream is not suitable for roof top mounting.

Further Information
For further information, please download the Skystream Brochure or the Skystream 3.7 Technical Specification document from our web site and you may also find the answers to some of your questions on our Frequently Asked Questions (FAQ) pages, as those form a complete guide to wind resource and turbine siting.

Wind Speed Checker

Wind speed varies with time, from nothing on calm days to occasional violent gusts. If the wind speed at a site is recorded over a year, it will be seen to vary about a mean wind speed value. This is the annual mean wind speed (AMWS) and is an indication of how much wind energy is available. In the UK, AMWS could be as low as 4 m/s (9.0 mph) for an inland site to around 8 m/s (13 mph) or higher on the most exposed sites.

You can get reasonable estimate of the 'windiness' of a site from its location. The UK Government funded a NOABL database which gives an estimate of Annual Mean Wind Speeds (AMWS) in meters per second (m/s) for each 1km square all over the British Isles for a height of 10m.

Services

Technical Support.
We will provide the required technical information to assist your decisions relating to placing a suitable wind turbine on your property. This will include the approximate annual mean wind speed in your area and an overview of the equipment that will be installed for your project.

Site Survey
We will conduct a free site survey and discuss all aspects of installing your wind turbine and address the suitability of the site. This information will also assist in the generation of a full quotation and subsequent planning and grant applications.

Turbine Location
All of our wind turbines have free standing towers and require a concrete foundation. Suitable stable ground is required otherwise piling may be required. The location of the wind turbine will also consider the direction of the prevailing winds and the vicinity of any other residence in the area.

Ideally, the turbine should be as far as possible from buildings or trees which may block the wind and cause turbulence. As a guide, the wind generator should be about twice the height of obstructions in front of it (for at least the prevailing wind direction). The ideal location is at the top of a gentle south west facing slope. The best location for your turbine will be established during the site survey mentioned above.

Finance. We can direct you to a Finance Company if you wish to consider paying for your turbine over a period of time.

Planning Assistance
Northern Ireland. Your planning application requires the appropriate form, a site location map with site boundary and access road, site layout and location of the turbine, details of foundations and information regarding the turbine structure. We will process your application including all of the above information free of charge. However, you are required to provide the planning fee (currently £230).

Wind speed survey at your site

If you are in any doubt regarding wind speeds at your site, we can install an anemometer at the proposed turbine height to conduct a wind speed survey at your proposed turbine location.

WIND TURBINES MAKE SENSE

An energy supply should meet the three criteria of:


• Sustainablility
• Affordability
• Reliability


All over the world, existing power generation by large fossil fuel plants consistently fails to meet some or all of the above criteria. Because of this, more and more small scale power supplies are being set up based on renewable energy technology.

This is described as "micro generation" or "personal power generation".
