Vertical wind turbines?

+460 for an inverter too.

Drawback is that the startup speed is 4m/s which is 14km/h, although will generate down to 3m/s

Then mounting/clearance from neighbours etc becomes issues.

I have thought about it too. But realistically I'd need to actually go and measure the wind where I'd put it.

Vertical do tend to deal better with less clean air than traditional turbines.

Sure it's rated for 2kw. But what does it need to get that power... Or what does it actually generate at start up speeds.

Power curve, it generates 3 phase ac, then the charge controller rectifies it to DC, then either a battery is charged or sent to an inverter.

It's quite big too. 1.2*1*1m.

May I ask what you got?

my nearest weather station with wind data, Is malin head. But its always windy there! Red line is 4m/s - (average windspeed per day) - you can pull hourly windspeeds from met.ie too.

Looking at the power chart, really you need to be getting 6-7 (grey line is 7) to generate anything decent.

Been looking for some sort of connected weather station for a while. (Rainfall mainly)

And if I can pull the data out live (ish) I'll be able to estimate production, and account for day/night use too.

Hopefully it might shine some actual numbers on wind. But as always it's location location location

The MetEireann API will return the forecasted winds for you lat/long. E.g.

http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=53.27;long=-6.32       

Which you can parse and extract out the windspeeds. Whatever about the solar radiation (which I've yet to validate with how the radiation forecasts compare to my own actual production) I know the wind forecasts are usually pretty good....at least within the forthcoming 24 hrs. Further out than 24hrs, the chaotic nature of the weather is harder to forecast, but all you need really is 12-24 hrs.

We talked about it in the other thread, but if your "out da country" and have the ability to setup a 800-1000w turbine on a 20-30ft pole, I'd say for less than €2K you could get yourself a 500-800watt turbine up and running with charge controller hooked up to a battery bank. I'd imagine it would have a reasonable return on vestment, if not, it would still be a superb fun project. Surprised there aren't more people on here in rural areas who have one?

I know, it's the curse of a housing estate. Even borderline like you idc, I'd say you would struggle. Possibly not with the wind side of things, but the neighbors and/or planning laws. I'd love to give one a lash - but I think anything decent (say 500w) would have a rotor diameter of 2ft plus. Even a super quiet one the bearings rotating away for months at a time will wear out and a squeek or some noise will develop and the neighbors will (rightly) complain that it's keeping them awake at night. Or they'd just complain for the sake of complaining.....there's always one neighbor who's like that, isn't there? Then they be off to the council that the pole is too high for the plot of land out my back yard, etc.

However, out in "proper" rural countryside with your nearest neighbor 200m or more away - ohh I'd be out with me shovel and spade digging the pit for the foundations no sooner than you could google "best wind turbine 2022" :-)

Interesting will have to google that, as i usually end up on the Tesup webpage when I occasonally check out what turbine options are available should i ever be mad enough to install one in my urban setting!!!

For reference, this is the inverter that Tesup use : If someone wants to ali express it :D

Note the startup voltage is also 50v
