Small Scale Wind Energy
Being at the forefront of Atlantic Jet streams flowing easterly over North West European, Ireland has a great wind resource and is one of the leading countries in terms of installed large scale wind capacity. Small scale wind can also be quite attractive in Ireland provided certain principles are adhered to. Sunstream Energy has over 10 years experience supplying and installing small scale wind turbines for residential, farm and commercial applications in Ireland. We contend that a successful small wind scale project depends on four main factors;
- An exposed site with annual average wind speeds greater than 6 m/s (13.4 mph / 21.6 kph / 11.7 knots).
- A quality well designed and manufactured wind turbine compliant with the international small wind turbine standard IEC 61400-2.
- The turbine should be properly installed in accordance with best practice guidelines, e.g. UK Micro generation scheme
- Application – the steadier the on site electrical load throughout the day and year then the more wind energy will be captured on site and conversely less purchased from the grid. This factor can be enhanced during windy periods by switching on discretionary loads such as water immersion heating, refrigeration and battery charging for recycling electricity during slack wind periods.
Over the years we have advised some people against proceeding with a small scale wind project on the basis that their site is unsuitable and/ or there electrical usage profile is concentrated in a daily narrow time span and to instead consider solar PV as a less expensive option. That being said we have many satisfied wind customers whom we have provided with a diligent and responsible service over the past 10 years.
Small scale wind turbine technology – “the good, the bad and the ugly”
- Keep it simple – beware of proponents of turbines with overly complex electro-mechanical control systems delivering superior performance. Usually such systems require more frequent and relatively expensive maintenance to keep in good order over the service life of the turbine. In our experience its better in the long term to loose a little in pure performance in turn for robust reliability and lower cost of ownership over the 20+ year service life of the turbine.
- Over-speed control in storms is the single most important attribute to the survival of all wind turbines. This is particularly relevant to small wind turbines not alone for survival but also for safety reasons. A well designed control system with few or no moving parts is always safer and more dependable than a complicated system with many moving parts.
- Always seek references from small wind turbine owners with a number of years experience as this is the best quality indicator.
We will be glad to advise further. Some examples of our small wind turbine installations can be seen in the “Projects” section.
Designed for homes and businesses, the Skystream 3.7 paved the way as the first compact, all-inclusive personal wind generator (with controls and inverter built in) designed to work in very low winds. It produces up to 400 kilowatt hours of clean electricity per month* and comes complete with Skyview™ monitoring software, so you can track […]
Entirely manufactured in Germany, the Lely Aircon 10 is an engineering masterpiece that is the result of many years of market experience. Right from the beginning, the objective was to develop a small wind turbine with strong performance, new technology and safety systems comparable with larger wind turbines. A special priority was to design the […]
