Re Ted "And not on the MCS list either".......they are on the MCS list (one of the first to qualify the Evoco 10kw turbine apparently,see website)

2.Re gustyturbine "It looks like a bag of nails to me anyway" .....I think the Evoco 10kw is one of the most attractive looking turbines on the market,and bearing in mind I may have to look at it for 20 plus years I'd better like what I'm looking at !! Compared to say the Gaia....there's no contest! Even if it is slightly more(the Gaia) efficient it looks sooooo UGLY (something out of the Flintstones !) and I certainly couldn't "live with it",beauty is in the eye of the beholder....absolutely!

3.I have emailed the company re cracked flanges and will report back with their response asap....thanks for this snippet of info as it could determine whether I actually continue to erect an Evoco(subject to any modifications the company may or may not undertake) once planning has been sorted (approval expected in the next 3 weeks subject to an Ecological Survey)

4.Thanks for the calculations Pauler....appreciated.

Quote from Julian Wiley, Chairman of Evoco -
“With MCS as the gold standard for quality assurance and consumer protection, Evoco are proud
to join the elite few manufacturers who have managed to pass this stringent testing regime to
achieve Clean Energy Cashback eligibility.”

The only relevant historical document I have is the transitional list dated September 2010, when the Evoco was listed as partially, but not fully, certified. So it was then a candidate to drop off the list pending completion of full testing.

But if you want to go for one, it is definitely on the list now.

Anyway, I've got a Gaia and I was also considering an Evoco initially. Unfortunately, my DNO said I would need an upgrade to my supply for the Evoco, which was the same £ as going 3 phase - then there's no real contest between the Gaia and Evoco on £/kw. I prefer the Gaia's looks but I would say that having spent £50K wouldn't I.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117716#Comment_117716 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117716#Comment_117716 Mon, 26 Sep 2011 08:22:52 +0100 windyboy https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117745#Comment_117745 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117745#Comment_117745 Mon, 26 Sep 2011 13:11:57 +0100 jonno http://www.greenenergynet.com/discussions/proven-implications-wider-small-wind-industry]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117807#Comment_117807 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117807#Comment_117807 Mon, 26 Sep 2011 21:53:56 +0100 windy lamb Took me a long time to choose a turbine and even longer to find an installer who had the experience, business model and contract terms that where acceptable to me - after all, it's my money not theirs! We had a number of visits by installers - most had similar conclusions re. the site but very different sales pitches. I ended up tendering for quotations after obtaining planning.
One installer stood out a mile. They where much better on price, delivery time, installation, etc, etc. My installer is local to me, maintains a number of Gaias and other turbines and has visited site promptly if any problems occur.

Plenty of fabricators could do it in the UK but I suppose not as cheaply. Good thing about a lattice is that if one weld fails you've still got another 500.

"Earlier this year we did find a crack on a weld on one of our turbines base plates. This plate is the plate on which the turbine generator is mounted.



As an MCS certified turbine there is a strict process that we have to go through if we find any product faults. We began this process alongside BRE (our certification body) and redesigned, tested and rolled out a retrofit base plate onto all of the installed turbines. At all stages BRE were involved with assessing this work and ensuring that we complied with the requirements of MCS.



This was a significantly costly exercise, however we completed all of this work within around 3 months. Our MCS certification remained current throughout this process and was not suspended."]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117988#Comment_117988 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=117988#Comment_117988 Thu, 29 Sep 2011 09:09:05 +0100 pauler

Shouldn't rely on that, though. The strength:weight advantage of a lattice comes from all welds staying put. Anyone who's done any explosives demolition will tell you that you can leverage the destructive power inherent in the weight of any structure to your advantage by 'simply' weakening it at strategic points. Think aircraft and metal fatigue!

Prof. J E Gordon is good on this.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=118462#Comment_118462 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7363&Focus=118462#Comment_118462 Thu, 06 Oct 2011 09:42:05 +0100 windy lamb After any warrantee has expired I could re-weld a joint in the lattice but not sure I could do the same to the retaining flange on a monopole!
I'm just about to experience 50-60mph winds so we'll see how good these Turkish welds really are!!]]>
