Title: Small turbines in residential areas
Post by: pantsmachine on August 11, 2019, 09:35:01 AM
Hi all, my mind keeps returning to the idea of a small wind turbine to augment the solar. Liked the look of the 15kw windmill version. Would use to keep batteries topped up and solar I boost running. Anyone tried putting one in a residential area?

The immediate answer to wind in urban residential areas is “chocolate teapot”.
So much turbulent air that you’ll never get proper air flow to the turbine if it’s anywhere near your house, and the noise and vibration if it’s mounted to your house will drive you and your neighbours mad.
Unless you have a big garden and are able to mount a small turbine atop a reasonably tall tower away from any other buildings, it’s really a futile exercise.

Apart from planning permission, possible noise nuisance, strobing, etc there are other issues.

Wind speed and variability in a residential area might be a problem, along with turbulence.

Insurance would be rather expensive, dependent on distances from neighbours’ properties or of rights of way.  Towers collapsing must be able to fall safely  within the confines of the property, I would think.  Losing one or more impellor blades could be lethal - they can remain airborne for some considerable distance - think here spinning seeds being dispersed from ash trees, for instance.

Overall, not a clever idea I would suggest.  But your idea of ‘residential’ may differ from mine.

Edited to add that a 15kW machine is not a small machine,  in my idea of a residential area.

Perhaps its one of 'those' type mentioned on here before. stir: (Physically small but have fantastically, physically impossible, high output).  ???

LOL,
apologies 1.5kw. I had posted the original on my phone. We live in a bungalow and I had thought to put it up at the same height as the tv ariel so approx. 10 mtrs off the ground. We have strong winds and we are relatively open in area. I had hoped that metalastic mountings and build quality of turbine itself would isolate any hum/vibration. I'll have a chat with my planning dept and see how they are. Anymore input from you guys on the 1.5kw level is massively appreciated. :)

I too have a longing for WT but after long consideration and much reading on this forum I've concluded it's only really useful  if your off grid and live in a rural area with appropriate geography - don't underestimate the amount of effort that's required to keep a WT up and running. 

I've replaced that desire with another, namely a secondary unsubsidised self installed SolarPV/Battery install allied with an hybrid ASHP - still working on that one!

I am sure there is a magic point in wattage and build quality where I can assist the solar. Had looked at the horizontals as well even with their inherent design longevity issues. I can certainly recommend the solar/battery array to you as a wonderful combo. I'd love to be able to splice in wind input into the goodwe charge controller for home/batteries/iboost/export. 1st step should be a wee wind monitoring device in spot I plan for to see if its even viable?

We had a 1.5 kW turbine (8m guyed tower)whilst living in France when the wind blew from the W/SW open fields it produced really well. From the N the direction of the house 50m away it produced diddly squat. Unless you have an enormous garden with no trees and are prepared to accept next to nothing production from that direction   chocpot:

For us worthwhile, it depends what you are looking at, we had no immediate neighbours so safety was not an issue.

Good luck.

Not really surprising!  Have you checked the maths to see if that output is possible at that wind speed?

Try it and see.

Hi guys, I would go for a vawt for less noise, smaller footprint, less output stacked up against less reliability. I am now at daft question stage, please don't mock.
If planning knocked back any discussion whatsoever I could put up a small vawt at the bottom of the garden and call it a temp structure. Here's the daft bit. If I buy a 24v dc 600watt purely as an example can I wire it into my ring main through the closest point (an outside workshop) and a transformer to 244v ac for example so it is pushing a small amount of power into my ring main whenever it spins?


Title: Re: Small turbines in residential areas
Post by: nowty on August 11, 2019, 04:43:41 PM
Ecogeorge has got one in his housing estate, thread below, but he even admits "it produces virtually nothing and only a smidgen when its windy".

https://www.navitron.org.uk/forum/index.php/topic,30407.0.html

Wind just does not scale downwards like solar does for residential generation. A solar panel will generate the same in a residential area or in a solar farm, but for wind you need a specific windy location, free of turbulence and the biggest turbine you can find.

If planning knocked back any discussion whatsoever I could put up a small hawt at the bottom of the garden and call it a temp structure. Here's the daft bit.

NO.  You will need a grid tied inverter exactly as you do for solar PV. Mastervolt used to do a Windmaster 500 which would do the job. 

Just to confirm what the others have said. I had a 1kW Futurenergy turbine a few years back. Initially I had it on a 7m pole. It had a clear view to the south west towards the English Channel and was some 50m from the house to the North East.  Luckily the prevailing wind was SW so generation was good with the wind from that direction. Anything with a Northerly in it produced next to nothing as the air was so turbulent. I raised the tower 2m to 9m which improved things quite a bit. I also got a modified longer tail from Futurenergy which reduced the useless swinging about in turbulent conditions.  In round numbers I used to get around 1000kWh per year from it BUT a lot of that generation was in big chunks. When we had a good gale blowing it would produce around 20kWh in a 24 hour period. So a lot less predictable than solar PV. I would say my site was pretty much as ideal as a domestic setting could get but as others have said they are noisy - very noisy. You will be on edge everytime a storm comes through - I never bottled out and lowered mine and it did survive windspeeds in excess of 80 MPH - but it made me quite nervous and frightened to go anywhere near it when the wind was howling. Flicker was also an issue - more for my good lady wife. In the low winter afternoon sun the blades used to cause an annoying flicker in our "sun lounge" at the back of the house. I kept it flying for around 5 years and it was an interesting exercise - and I do occasionally miss it BUT it did need a lot of maintenance, constant checking the tower and guy wires, slip rings etc. So I took it down and sold it on while it was still serviceable and worth something. In terms of maintenance, remember it is not an easy job raising and lowering a 9m tower with a heavy lump of turbine on top.

If it was me I would spend the money on more PV and/or a bigger battery.

Roger

Cheers Nowty,
I read Eco George post when it came up. We see outstanding crosswinds at our location. Regarding turbulence i'll have to see. It's a cracking big garden so hope springs eternal. Pretty sure I want to to try a hawt and see if I can match it to the house background draw and dump excess to earth purely as a way to A. Gain knowledge of area with regards to potential wind for scaling up & B, just for a laugh. C. Would take X amount back into batteries quicker via the solar and allow more watts to go to the Iboost, without breaking into the workings of the Goodwe Hybrid controller as is with the panels and batteries. Totally open to all advice.

Edit-Marsh man,  outstanding, thanks. Lots to digest and run thru the remains. Why such a strong NO, details appreciated to help me on this learning curve.

Just "NO" (to all types / designs / size) in  residential areas.

Navitron forum has oodles of archived material on the matter from the dark "swindle-save / swindlesave" period.

If you need to convince yourself further look those up, plenty of it back in the day.

One of the last times we discussed these was when some architects vaunted their integrated design in London flats, sold on its "potential" (they had millions in backing obviously) they were built, & turned off from a combination of resonance & debacle performance.

Plenty of data that should set you in the right direction (which is when you are a fit, able, obsessed, engineering capable, shed full of tools, cable laying  land owner of a big BIG open space that has already been tested for wind performance, & you have mates to call on to help you out take it down for servicing / incoming gales etc etc.

If you don't tick all those boxes you'll have a  heck of a time, they require a lot of coaxing along on a non commercial environment set up

Swindlesave got govt backing as a fit & forget, employing double glazing type tactics of salesmanship from a group who knew ala Gerald Ratner that they were selling "utter cr*p"

We all hoped that we'd be proven wrong, ..we weren't & that includes VAWT that keeps popping its head up periodically as "new".

Sometimes domestic WTs are a useful way of getting the local planning department to agree to a dreadful building on "green" credentials:

We have been living off grid for 10years plus,
                                            So a wind turbine in winter is a must for us. We have a 2kw Chinese Jobbie a first cousin of Tod,s Turbine and It is cut down to 1.5kw as is Donegal,s 2kw brother turbine  ,which also switched to the smaller blades.
   I got a small 450watt x 12volt Yang-Shen W/T to start with and learned to fly that before graduating on to the 2kw baby. After a few years of brown trouser excitement with the 2kw W/T on large blades,, I had an inspiration and downsized the bladed to the 1 kw output. Suddenly everything fell into place. We got got output in low wind speed and it could ride out the force 8s and 9s if I forgot to take it down or did not get home in time. I always believed in lowering the turbine in anything over force 8. Not because it would get damaged but because I know that our bank can only hold so much reserve and then the rest is stored in hot water. The turbine gets thrashed needlessly, so lowering to 10ft meant that it still performed and braked but not as violently as it does on the 13mtr tower.
   In winter when the sun don,t shine, Our turbine is a good friend and really does the business or "cuts the mustard" like AG says. So A decent wind turbine is a must for us. Marshman more or less nailed it and if You are on grid, PV is your best bet, It is dependable with next to no maintenance and good returns. I just love the idea of the wind turbine working right through the night, for us to wake in the morning with good hot water and a full bank.But like Roger says, they need maintenance and care.We have had a few members in the past who erected small domestic wind turbines next to their houses,
One chap stuck his on the gable of his semi, and we got to read all the complaining letters to the council. Such antics got no support from Navitron. They do nothing for renewable energy and usually end in disappointment. Do not bother with a VAWT, Once upon a time I also believed that they might be the holy grail if the design was adapted  to cater for a shield, a wind scoop and a tail to direce scoop into the wind. I kind of lived in denial for a few years ;D, ( I can do that no bother to me) but then the magic of the 3 vertical blades facing int the wind from any direction finally sunk into my brain. The VAWT can never compete with that. I know,, I know !! The world is full of VAWTS but then the world is full of helpless people as well. I refuse to lower myself and say idiots. "Helpless" is better.
             Have fun,
                         Biff

If it was me I would spend the money on more PV and/or a bigger battery.

I did go through a similar thinking period about home wind turbines as Pantsmachine is right now, and maybe he has got some better conditions and space for it. But after reading the advice on here I went down the road of more PV and more batteries. Especially as PV has got so cheap and managed to source enough reasonably priced second hand growatt batteries.

So, I think Marshman is on the money here.

I have just signed up to the Octopus Go tariff at 5p / kWh for 4 hours a day and hope that my battery is now big enough.
I will just have to imagine my imaginary turnip is blowing at a constant 6kW every day for those cheap 4 hours charging me up on all those dark winter nights without any worry of  sh*tfan:.

Good man, ..your other half would likely never allow you to do anything else "renewable" if you failed with a wind turbine, best to maintain relationships without the dirty overalls worn for raising / bringing down a turbine, fixing it & finding spares etc.

Everything has a resonant frequency, & a wall / roof mounted wind turbine will always find that via voids & materials used in construction, damping materials only do that, take the signal frequency down which can be a "biatch" you'll never solve.

Flying blades lost in the ground (distances flung also recorded here on navitron)  etc, etc... I too am a fan of wind power, but having had hopes dashed (for all the right reasons) here on the forum just take greater pleasure in the commercial ones down the road from me.

Glad to see you understand the general "been there, still wearing the washed out t-shirt" of old hands

Thus anything archived or current you see referred to as a chocolate teapot /  wacko  here has generally, a longstanding proven history of snake-oil / bad design  etc.

please be aware I'm not suggesting you try these out.
But when I went to FullyCharged Live back in June (which was excellent), amongst the many exhibitors of solar PV, batteries, EV chargers, BEV lease/hire/sale companies and others, there was also one stand who were trying to sell this as a solution for residential roof-top wind generation.

https://gigaturbines.co.uk/

I did try and be nice to the chap and let him do his sales pitch, but ultimately it is still a load of chocolate hot beverage containers.

Found the Giga's yesterday. Had a look, this will run around in my brain for a while yet, I can see the huge pile of why not to. We do rather well with compromised split roof solar and batteries. Tbh, it's outstripped all my expectations and we love the fit and forget aspect so can see how wt is a pita in comparison. I'll see how bored I get over Winter. There is a spot 100 ft down the garden..... Humans eh? :) With all I have read the last part to die is that appeal of a small quiet vawt Birling away doing its wee output thing 100ft down the garden. Even throwing out 300/400 watts would make me happy. Extensive research to completely endorse all you guys are saying needed to just shut myself down. :) I thank you all for every single bit of input ongoing.

To be completely fair & accurate that pic is to show portability,, prior to camp set up (presumably) & the 2018 kickstarter I had a nosey at also mentioned USB chargers, I guess if we break through the marketing BS that's how it plays out, using stored charge on the move that was harvested previously, not a spinning, charging micro turbine.

But yep, still.

Hey Guys, I resisted the wt urge for a good while then swmbo started on wouldn't it be great in the Winter months etc..  TBH, I caved really easily!

Hey ho, next up I've got a 12v ac 3 phase 600w vawt on its way from china. Built a pole( forgot how much I enjoy fabrication and welding), vibration isolated at 3 points. All running into a 80 amp leisure battery out of my Bongo via a wild ac to dc controller and out via a 800watt capable 240 ac inverter. Fitted the blades last and it started straight off, not stopped since (ahem 2 hours)!

Well done Pantsmachine,
                     I have no alternative but to heartily commend you for your contribution to RE,
    This is just a small step to much greater things. The bug has bitten and now you will be up all hours of the night looking at the clocks ,,amps -- volts and--watts.
 You will have pen and paper and documenting the sudden surge of power at 4am. I am guilty of all these things and much much more. What ever you do my friend,
 do not attempt to share the surge in power figures with SWMBO at 4am. I have a SWMBO also and believe me , Sharing such exciting news at that time should not make one feel unwanted and unloved but I did note that our Hounds at the time who shared 120kgs of muscle and bone between them, had also begun to glare at me.
    Anyhow, That is all behind me now. All the pens and paper keep disappearing and If I do manage to lay my hand on a pen, I get somehow distracted with an offer of a cuppa and a lump of  cake, And The pen never mind the paper become things of the past. And yet I know that somewhere in our house is a treasure trove of notebooks and pens,pencils and even a feather quill and 2 bottles of ink,
  I am not accusing anyone but sometimes when I lie abed, I become positive That somehow or other, My wife lies much higher than I, She tells me That I have been eating too many potatoes and cream buns and got so heavy that my side of the mattress has compressed beyond belief. I have to agree and say,,Yes I see what you mean. It is much safer you see.
    So from one turbineer to another, These Swmbos are not keen on early morning figures and calculations.
  On a more serious note, It might be a really good idea to put a 6mm wire cable around the upright just above the second horizontal support bracket. Secure the cable to the upright with double locking Ubands, Then feed the cable through the wall and anchor it in such a way that you have 200mm of slack and no more. This is just a form of insurance for you and your family. A turbine in a force 3 to 4  in no way resembles the same turbine in a force 7 to 8. This is serious stuff. The real problem starts when the Turbine starts braking at speed and a resonance starts to build up. The 6mm wire cable will ensure that the steel and heavy stuff do not fall on anyone below., It will also show that your are taking steps to prevent any serious accidents.
    Good luck,
               Biff

Hi PM,
     You are not alone . Mugsy here had not one,,, but two small 300watt turbines stuck on on a scaffold on our north facing gable.. Then a 3 day blow came along , force 8 + and all that exciting stuff. The two turbines were about 4 feet from the Gable and about the same height above the roof as yours. We had 72 hours of the most disturbing  and violent racket that could be felt all over the house.. When it was over, "Hans " the Aelous 300 was no longer working but our Yang-Shen  was OK.. If I had attached them to the gable at roof height  they would been much worse.

Post by: biff on November 29, 2019, 07:28:36 AM
I do remember my own excitement  when I erected my first turbine, It was a 450watt  Y/S. It did quite well next to the gable about 4ft away and above the roof. There was some noise but it was bearable.  The Aelous was supposed to do 500 watt but could clock 200watt  if pushed. The two turbines were within 8ft of each other. The Aelous was described as the answer to overspeeding because when it started picking up speed,  the blades bent and built an air dam in front of themselves, what it did not tell me was that while creating this speed lowering air dam,  it also made a horrible racket..when the storm got going and  "Hans" went into overdrive and also made a vibrating howling noise that shook the whole roof  and it sounded as if the Aelous blades were actually flapping against the actual roof. It was great hands on experience and I learned from it. ( not a lot it seemed) I cannot claim that I was not warned but by gum it was  some buzz.
