    Who's doing it for you is it the gaia team
    Nope it is the installer Sustainable Energy Systems. They are really good and know their stuff, so should hopefully get to the bottom of it.

    A lot of these problems are due to fluctuations in the main power grid. Ours is appallingly bad but improving due to more turbines keeping voltages steadier. About to start on a C&F myself I hope.

    Ahh i see yeh that will be what michelle was trying to tell me then. Not sure how difficult our area is because there are no turbines near me. Cant remember exactly how much but Gaia are basically saying give us 2 or 3k and we will get planning then if your still keen on putting turbine up then they will take the other 60 odd thousand off us and we will go to the next step. But its alot money if they then find they cant get planning

    If I were you i would do the scaffold pole option. start with a 3-4 inch 6 meter pole and work down. Either weld a plate on end and bolt together or wels tubes on so they slot into each other. With a decent plate on top to carry annometer and tie wires (3 or 4) to some pre pored concrete in holes a suitable distance away you should be able to put up something fairly cheaply I would have thought. As long as not near any footpaths and you stick a fence round to keep stock away it would do job for 12 months data."


    Or conversely... old electricity pole with various lengths of box section/angle iron bolted and welded on top... pick it up with the forklift.. stick it in a 1 foot deep hole and hold it up with 4 ratchet straps fastened onto spikes hammered into the ground.. and bobs you uncle an anemometer tower.. took us an hour or 2 to do and has been up since january and hasn't moved an inch..

    Re: My Gaia Wind turbine project

    The herdsman and i attempted to put a mast up last night made from scaffolding poles. Turned out to be a bit tricky in the end because the manitou wouldnt go high enough and the 3 scaffolding poles were very heavy so attaching 4 at once wasnt an option. So this morning ive ordered a 15 metre mast off ebay for 200. Last week the cheapest was 600 which is why i didnt bother. Yes the guy in the cradle is pulling a moony because he was getting cold and fed up

    early full moon then chippy:lolk:
    Looks a good spot from that angle, if behind is the same should at least get clean wind, keep the herdsman out of the way though:lolk:

    We have done 4300kwhrs now which is 3 weeks tomorrow, think we have the teething probs sorted- touch lots of wood etc etc. They have widened the voltage parameters on 2nd turbine and not stopped except through the lack of wind since, so hoping its now ok.

    Still have some finishing touches for the install, covering cables etc, have started filling the foundation back in but nearly done and dusted, dont know when they coming back as yet but not too worried as we are running and havn't paid all money yet so they will:lolk:

    Cant See excactly how you are connecting each scaffold pole together. I weld a slightly larger tube on the end of each pole to drop the next pole into as a socket. When you have 3 poles up assemble last 2 poles on the ground. Set them vertical and tie to thefork lift cradle securely.

    You should be able to lift enough height to drop it in pole 3 or pole 2 to gain some extra height worked for me Think mine is sitting at 18 Metres,

    Re: My Gaia Wind turbine project

    Thats what we did BOB1 but because the poles werent a tight enough fit, when there was 3 attached they swayed about alot and it was a bit windy so we gave up. the scaffold poles connect by hammering a bit of metal in after you have slotted them together and then they already have holes drilled so we put a big bolt through as well but there was still too much play. The 50 foot mast i bought was stolen along with the rest of them so the guys given me a 40 foot one at half price

    Interesting reading. If you were to sell all of the power produced back to grid rather than using it then how much do you get per KW?

    Are you on track with predicted output?

    Re: My Gaia Wind turbine project

    The figure being spoken about is approx 3pence/unit sold back in to the grid.

    We are paying approx 10.5pence/unit so much better using as much of it as you can.

    The feed in tariff is what makes it worth while, for turbines under 15kw output its 28pence/kwh and over 15kw its 25.3pence/kwh. This is paid for producing the power regardless of where its used.

    As had been answered, its the FIT and the saving by using it yourself that makes the project rather than selling to the grid. We will get 25.3p per KW/hr for all we have produced and we average about 8.5p per unit to buy it. This month we have used pretty much all produced but dont think that will be the case every month.

    Our electric bill will only be 190ish pounds compared to the 550ish normally and most of that is from before we went live i.e from the last meter reading in April. Add in the FIT and we have made a decent return in 3 weeks, that is why the payback period can work out, but as said I think we have had 3 good weeks. If we get 60000 per year it will be good so need an average of 5000 per month and we are well on the way to that with a week to go.

    Re: My Gaia Wind turbine project

    Finally got my new mast up 46 foot in the end. Should be 50 foot really but the scaffold pole i pushed into the ground only had 6 foot sticking out and the 50 foot masts all got stolen. I just need another guide rope but will do that tommorow. So now ive just got to look forward to seeing what it says in a months time

    Re: My Gaia Wind turbine project

    our gaia had its annual service yesterday. all went well. it has done 4600kw in the last month which is outstanding. according to the serviceman the highest performing gaia in n.ireland this year has done 38mw which is rather impressive.

    Re: My Gaia Wind turbine project

    That is very impressive, ours have just done a combined 5100 in 22 days, so I am happy we have hit our monthly target and that is with the teething problems meaning we have lost probably 2 whole days with 1 turbine.

    Hopefully we will build up a bit in reserve over the next week because I cant see every month being as good as this one looks like being.

    Chippy does your annometer show the daily wind speed or do you just have to take it down to see what its done over the intervening period?

    About 250 meters from the supply at the dairy/milking parlour which is another 35ish to the actual incoming supply and DNO meter. Why?

    No it doesnt show daily wind speed on the device itself but when i take the SD card out and put it in pc and upload the data onto the companys website then it may show daily wind speeds then. Im not sure yet. I think it just shows an average over a certain period.

    Anybody any ideas how to get an export meter fitted quickly to get me up and running having some trouble getting one fitted as my supplier just now has none left and have been advised to get one fitted myself to save time and costs Its driving me round the bend

    Re: My Gaia Wind turbine project

    By export meter do you mean changing your DNO supply meter? Or do you mean the box that shows your production from the turbines? If its the former and you have an old type meter I wouldn't be in a rush to get it changed. If you need that explaining PM me

    NOOOOOOOOOOOOOOOOOOOOOOOOOO

    It fell down :cry: I must have got the scaffold pole joiner too tight. Was up before breakfast this morning then after breakfast herdsman rings and says your mast needs a bit of viagra

    Distance isnt exactly an object with the gaia, but the further away the bigger the cable as it kicks out mains voltage at the turbine and so needs a bigger cable in order to avoid voltage drop.

    Yes it is 3 phase, I believe it can be done on single but is rare, other makes do single phase easier for definite though. I can put you in touch with a couple of firms if you want?

    i looked at using scaffolding poles and the reason i didn't use them is because i thought they would do exactly what yours have done..

    yesterday my tower was taking 20m/s winds no bother

    Re: My Gaia Wind turbine project

    I think that is why he needs to start with a bigger 3 inch pipe at bottom and reduce in stages.

    Had a fault again today, went to see why they wern't working, thought becalmed but would see what computer windspeed was anyway.

    Opened control box and computer not powered up. Had come back to farm and the breaker on our fuse board had tripped for some reason. They used an old one already on the board for connection and are supposed to be changing it but havn't. Think I will have to get onto them to do it, it did reset but took a couple of goes so think it is dodgy. Back running now but not doing much, windspeed only around the 2ms mark at moment.

    Re: My Gaia Wind turbine project

    I think it bent because its not scaffold pole! Only the bottom pole is scaffold, the rest is this light weight aluminium stuff that gets smaller and smaller and weaker and weaker as it goes up but even the bottom pole is no where near as strong at scaffold. The mast only weighs 22kg where as 40 feet of scaffold was over 100kg! The scaffold was just too heavy for us to lift up but im sure i would have managed in the end.

    Whats the minimum wind speed that will turn your turbine Bigandy?

    Hi Chippy,
    they have set it to start up at around 1.9m/s but it doesnt generate until 2.2 I think.

    Was interesting to look at this morning actually as wind speed was very marginal and it was consuming power to get going, then was on border of just generating, to going into free wheeling mode which means wind turns blade but not actually producing power, then cutting into generating mode and back into free mode etc etc. Wind picked up again since and generating properly again but not too much.

    Crikey that's quite low parameters
    Ours is set at about 2.5-3m/s
    What's your average in your area

    see 1st post for the NOABL speed, as I say there its officially 4.8 but on farmhouse postcode, not where turbine is, but all round is higher, so think its more likely 5.5 or more.
