Iskra AT5-1 5Kw Turbine
by Cliff Collins at 2008-03-29 16:39:53 (Forum::Public::Wind)
Is anyone else having problems with this machine, particularly with the "mooing" whine?

Ours has been installed for 9 months and is still not working.

We paid a deposit to Segen (Iskra's agents) 13 months ago, and finally - two months later than scheduled - our AT5-1 was installed in June last year. From the very first day, it never worked properly, and we have had huge problems with aerodynamic noise and a very loud whine/hum, known as the "moo". Segen and Iskra have had the benefit of more than 19,000 of our (and tax-payers') money for 9 months and all we have is a sad, still, turbine.
Very little help from Segen, who - we feel - should be batting on our behalf.

I don't own a turbine like yours but I would suggest that you contact your local Trading Standards officer at your local Council, and a solicitor or the Citizen's Advice Bureau. You have rights under the Sale of Goods Act. If your Turbine has been that bad you should be able to have it removed and get a full refund. It is not a cheap toaster or a throw away pen, it cost you 19,000 so should work. Don't be afraid to make a fuss, you were sold a Wind Turbine, not a garden ornament.

Also, contact the Energy Saving Trust who gave you the Grant. They are very interested in problems with Turbines and Installers as they give accreditation to both. They can get things moving as they hold the purse strings.

I am lucky. I had teething troubles with my Proven, but my installer went to great lengths to find a solution and ensure I was a satisfied customer. Still does.

Is it in order to name that supplier and give them some credit publicly?

You may wish to ask for the Iskra to be reviewed here and to let subscribers over there know what your experiences have been. -- muymalestado

In view of their alleged poor service, I am very surprised that SEGEN are allowed to advertise and/or have a web link on this site. Could it be a case for the webmaster to invite SEGEN to explain their apparent lack of action with a threat to remove their link? Proven have come in for some criticism on this site (some of it from me and fully justified) but they provide a Rolls-Royce service compared to what has been reported for SEGEN / Iskra.

Presumably the contract was with SEGEN, if they have difficulties with Iskra that is their problem, not Cliff's.

I've emailed Segen yesterday morning pointing them at this thread and inviting them to comment or give a statement.

I think it's only fair to give them a short time to compose any reply they might want to send.

Our neighbours bought an Iskra AT5-1 from Segen. They located it 75 yards from our property against Iskra's own advice of 100 yards (and then they changed the advice on the website). The bloody thing has this whining moan day and night. Keeps you awake when you are trying to get to sleep. Wakes you up in the morning. Our neighbours have complained, we have complained...
Despite a continuous stream of promises that it will be fixed, it isn't. We have had to put up with the god-awful moan from this thing for 18 months.
What can we do?

Re: Iskra AT5-1 5Kw Turbine Tony Smith - 2008-07-13 21:37:26
That doesn't sound good. Have you complained to Environmental Health? You should be able to get the noise level measured, and if its above acceptable limits then you should be able to get them to take action.

Note that our Environmental Health in Aberdeenshire work to the WHO limits of 35dB for sleep disturbance, rather than the higher figure of 40dB used ETSU-R-97.

These small turbines seem to be seriously lacking in noise data. I couldn't get a straight answer out of Proven. In our case I'm more concerned about noise for us than for our neighbours who are around 450m away.

Re: Iskra AT5-1 5Kw Turbine Cliff Collins - 2008-07-14 13:41:41
Thanks for all the responses to our original posting in March. We haven't been on-line since then because we asked our solicitor to take up our case, and thus could not comment publicly. Starting legal action was an absolute last resort for us: - we had already 'rejected the goods' as unfit, we had spoken to Trading Standards both here in Sussex and in Leicestershire (where the turbine was made) but were getting nowhere. We met similar brick walls when we complained to the BRE, and even to the government departments involved in giving us our grant. Apparently no-one 'official' seems to care that 5,000 of taxpayers money has effectively gone into a turbine which has sat unused and thus generating nothing for more than a year.....

The Solicitor's involvement prompted a small ex-gratia payment from Segen in May, and a promise to keep in close touch with us if we would agree to allow Iskra another 3 months to try to solve the problems. If, by the end of July, they couldn't "bring the noise down to acceptable levels", then we would all discuss removing everything. Further to our agreement, we heard nothing until July 4th, when we were sent a copy of an email from the CEO of Iskra to Andy Pegg at Segen. It would appear that Iskra engineers are in the final stages of testing 4 seperate possible solutions, which - if succesfull - could be implemented within 4 - 8 weeks. So that's where we are now. We'll keep you all posted.

Chris, I hope this info is useful to you. Perhaps you could show this thread to your neighbours? We installed our turbine on our farm land 125m from our neighbours (and 140m from our house) as advised by Segen. Our neighbours now hate us and no longer speak to us, despite the fact that we have never switched the thing on - apart from a few short testing periods last June - because of the noise which drives us nuts!

Hello Tony,

I have a Proven 6. It is 55m metres from my house and in a severe gale with the wind blowing directly at my house I can't hear it through double glazing. Outside in those sort of wind speeds it roars like a helicopter but the noise is soon lost against the wind noise in your ears. 200 metres away in a severe gale it can occasionally be heard downwind, but only if you are really trying to hear it. In normal winds it occasionally ticks, rattles or squeaks, but normally there is a swooshing sound that I don't find annoying. Having said that, it is making my electricity. If it belonged to some-one else and was within a couple of hundred metres of me I might find the faint background noise of it annoying on a quiet summer's evening.

On the subject of the Iskra turbine noise, I sympathise fully with the problems being experienced. As I said before, I had problems with my Proven initially but these were sorted out eventually. Proven dragged their heels a bit at first but came up with a solution. Getting Trading Standards and the Energy Saving Trust involved in my case helped, so their lack of help in the Iskra case is a disappointment. On paper we have rights as consumers. In the Iskra case it seems that the reality is somewhat different.

Re: Iskra AT5-1 5Kw Turbine Tony Smith - 2008-07-15 11:07:16
Thanks PJ. Informal reports like that are encouraging. Its a shame the makers don't provide proper noise data though and I've seen a planning application in Aberdeenshire knocked back for lack of that data (although granted on appeal).

When (if) our plans go ahead I would like to be able to show Environmental Health some proper data. If it can be shown that the total noise is below 35dB at 10m/s wind, then there's no need for background noise surveys at neighbours.

Re: Iskra AT5-1 5Kw Turbine BigSkeff - 2008-07-15 12:35:52
Hi Tony,

I've attached the 'Noise Emission Report' for a Proven WT6000 Wind Turbine Mounted on TM1500 15m self supporting tower. I downloaded it in June 2006 from the Proven site and passed it to the Environmental Health guys at East Riding County Council, so they could have a good look months before I put in for planning.

That way I could be sure they were happy before I wasted time and money on pursuing the project. In the event they were totally happy with the reports findings and all went through without too many hiccups.

Any good to you.

Definitely useful. Its a shame they don't quote figures for 10m/s though.

Re: Iskra AT5-1 5Kw Turbine Bryan Rendall - 2008-07-16 09:26:11
Hi Tony,

I have attached the noise report for the Eoltec Scirocco 6 kW turbine. This was the first noise report for a small turbine to be done fully in accordance with IEC61400 part 11, the same standard as used for noise measurements on large scale turbines.

This was done in early 2007 and is the standard submission used for planning applications. It contains both measurements of turbine noise at 4-10 m/s and estimates of actual noise levels at 4-10 m/s for distances up to 500m from the machine.

Cheers

Re: Iskra AT5-1 5Kw Turbine Tony Smith - 2008-07-16 12:48:55
Thanks for that Bryan.

The table at the end indicates that it should be OK at 125m, complying with the PAN45 "simplified noise condition" of 35dB, without needing to worry about background noise. Even at 25m it would comply with the standard used in Aberdeenshire for properties with a "financial involvement".

By the way, we'll be in Orkney for a few days later this month. Is there an Eoltec operating on the Mainland that could be viewed without any formality? We may possibly visit Sanday and Rousay but that's not yet decided.

Thanks,

Re: Iskra AT5-1 5Kw Turbine Bryan Rendall - 2008-07-16 14:15:32
Hi Tony,

Yes there are quite a few on the mainland you could see without fuss. The easiest one to access is Burray Community Centre. Its in an area of rough ground beyond the playing field, but still by the road, and easily accessible without having to go and ask permission. If you come over on the ferry from Gills Bay to St Margarets Hope, you'll drive by this turbine on the road to Kirkwall.

There are privately owned ones in Harray and Deerness that you could see. The one in Harray is near Corrigal Farm Museum and the owner there, Geordie Petrie who gives us his figures for this forum, is a very friendly chap who loves to enthuse about his turbine!

There are 2 turbines on Rousay if you decide to go there. Both are near "the" road, so if you take a run round the island, you'll pass by both. Both are privately owned, but I dont think the owners will be too concerned if you stop by the side of the road and have a good look and listen to their turbines!

Cheers

Hi Jim,

No, ours is still not working though we have received a couple of optimistic emails from Segen. Apparently Iskra are confident that they will have it fixed soon.

We'll keep you posted, and thanks for your concern.

hi i know several folk who have had them in since last year they have all worked perfectly give them some pain its rediculous and if they are still sat on your cash well!!!!! we found them all very nice to deal with cant understand whats gone wrong here but its definately not on!!! and you shouldnt have to stand for it! i certainly wouldnt be so nice!

Re: Iskra AT5-1 5Kw Turbine Chris Bower - 2008-09-07 17:24:18
Just to keep you updated... I received an e-mail dated August 2008 from Pete Allen of Iskra. He hopes to have a fix in the next 4-8 weeks.

This would be quite heartening if I did not have an e-mail from Pete Allen stating that he hopes to have a fix in the next 4-8 weeks dated August 2007.

Do you think Iskra are serious about this "fix" or is it just a ruse to win more time while they sell yet more of these noisey turbines...?

Re: Iskra AT5-1 5Kw Turbine Tony Smith - 2008-09-07 18:55:59
Personally I wouldn't trust them after all this time. Can you not get the machine shut down until its fixed? That might give them a bit more incentive.

Re: Iskra AT5-1 5Kw Turbine Cliff Collins - 2008-09-15 18:39:27
Tony,

It's been shut down (i.e. never been useable) since it was installed, so sadly that point doesn't make any difference.

We couldn't use it anyway - even if we wanted to put up with the noise - as the main on/off switch has broken.

What a shameful circus!

Re: Iskra AT5-1 5Kw Turbine Cliff Collins - 2008-09-15 18:34:23

Hi Chris,

We had that same 2007 email, too. We were supposed to have heard from Andy Pegg at Segen last Monday, but (as usual) have not been able to raise him.

We've already formally rejected the goods, written Solicitors letters, and been in contact with just about everyone we can think of to try to get the situation resolved, but it's quite astonishing how little response we've had.

We're reluctant to tell Iskra to take the whole lot away as we've invested not only a lot of money but also a lot of time, ourselves and our energy in this project which we desperately want to work (my wife was driven nearly mad in tryng to get sense out of EDF, for example).

It wouldn't be so quite so bad, though, if Segen actually even tried to pretend that they care.......

Maybe it's time to find out how many other disaffected Iskra wanna-be users are out there, and perhaps go to the national press?

Cliff

Hi , I've had my Iskra R9000 up for a month now ( same as the AT5 , just cosmetic changes). I did a truckload of research , including looking seriously at the Proven 6. I paid more like 25,000 - which was the same as quoted for the Proven 6. I went for the iskra since it seems to have better power curve ( under 7m/s) and I was restricted to 5KW input into the grid by my electricity company - watch this - they tried to limit me to 4KW unless I spent 10,000 upgrading their transformer. We've got a good site - apparently 6.5 - 6.8m/s . In a not particularly windy month we've generated 820KW , & only bought 23.00 of electricity in ( family of 5). So in this very short sample time its doing what its meant to . I'm hoping to generate about 10,000 / year. The Evance "estimate" for this windspeed was 12,000+ , we'll see.
Mooing - yes it does , no complaints from neighbours yet , but definately MOO'S at several different frequencies , and could be annoying - I've mentioned it to my installer & I'm going to monitor it. Blade noise: Sounds like a helicopter is landing in the field ( 100m from the house) in very windy weather , otherwise just a rythmic whisper. Nothing can be heard from inside the house. Am I happy so far? - delighted ( but skint) ....Jamie
