Gaia-Wind passes the MCS test...again!

July 17, 2012

We were very pleased on Thursday of last week that the Gaia-Wind 133-11kw turbine once again passed its annual Microgeneration Certification Scheme (MCS) inspection.

MCS is a vital part of the quality assurance that the industry owes to its customers. The Gaia-Wind turbine was among the very first in the country to achieve this distinction and since then we've been working hard to improve and develop our product even further. MCS accreditation is not easy to get. But it is without doubt, one of the foundations on which we can build our business and our industry.

Always check the sales claims

For those looking to compare and contrast turbine models MCS is a very good starting point. MCS is also, crucially, a tool for separating facts from advertising claims; real performance data from salesmen’s’ patter. Products have to be independently tested, so potential investors in small scale renewables can compare like for like characteristics that have been independently measured and published as part of the MCS process.

We sometimes see what I will describe charitably as over-enthusiastic claims about for example, small wind turbines’ noise levels, or production capability - and therefore potential financial returns. These can be checked by simply comparing the independent MCS test results for certified turbines to the claims. 

Forget rated power

Similarly, we often see wind turbines being described by their maximum power output or ‘rated power’ in kilowatts (kW).  This often represents merely the manufacturer’s own “rating” of their products, often at very high wind speeds (usually 12m/s or more). This can mean that the turbine will only produce its rated power when the wind is blowing very hard – which is not that often.

So it is more sensible – and more helpful to potential purchasers, to see how much power a turbine will generate in the more moderate wind speeds that are frequent in most parts of the UK – in the range of 4.5 – 7.5 m/s. Again the MCS helps here; it sets out independently achieved results...not claims.
