Re: Camelot Members Annual Green Electric Generation
Update time,
In an average year 55 Camelot members will generate 307 MWh of renewable electricity onsite and 170 MWh remotely.
Onsite Generation
PV - 292 MWh
Wind - 13 MWh
Hydro - 2 MWh
Remote Generation via Coop's
PV - 0 MWH (there are definitely some but I don't have any meaningful figures)
Ripple WT1 - 37 MWh
Ripple WT2 - 129 MWh
Hydro - 4 MWh
Keep em coming, there must be more of you out there generating.
Publicly reply to this thread or PM me with your PV (kW installed or annual kWh), ripple windfarm or other generation.

Re: Camelot Members Annual Green Electric Generation
Hey Nowty.
11kW Evoco wind turbine. ~127MWh since 2012. When it's running it does fantastically but unfortunately it hasn't been running for much of the last 10 years. We're on course for well over 30MWh this year though, thanks to John at Waltonwind.
You can also include 2x 40W solar panels on my homemade trailer-caravan if you really want! Nothing else electrical.

I'm gobsmacked that you have all that wind power and not a sausage of Solar PV.CharlieB wrote: ↑Wed Jul 13, 2022 2:39 pm Hey Nowty.

I am intrigued to know why ?
But no matter, your wind machine has taken us over the 1/3 GWh of annual onsite generation with 58 members.

Re: Camelot Members Annual Green Electric Generation
This is grid connected. I installed the wind turbine back in 2012 when wind made sense (kind of) and solar didn't. It's a great wind site, at a holiday cottage not my actual home.
If i had the £50k to spend on generation now I'd probably max out on PV, but I'd still do the calculation to work out what was likely to generate the most per pound spent. The way I see it every kWh generated at home is a little bit of coal or gas not burned, regardless of whether it's exported or used onsite. I've never been interested in trying to use it all onsite via immersion heaters or, even less, waste 20% of it in a battery cycle. (That said I am aware, and happy, that the turbine has undoubtedly generated more kWh since 2012 than I've used at any of the flats I've lived in.)
"But no matter, your wind machine has taken us over the 1/3 GWh of annual onsite generation with 58 members. ". Glad to have made my contribution!

20% waste on a battery cycle! I thought it was more like 6%?

Re: Camelot Members Annual Green Electric Generation
Depends what your measuring.
DC in and out of the battery, yes lithium is about 5% or even less. My old forklift LA was about 10%.
But if your charging from grid, there is the AC to DC loss and then back again from DC to AC, both those losses can typically be 5% to 10% depending on load.
And even if your DC coupling charging there is the DC to DC conversion loss.
Someone posted this on St Elsewhere a long time ago and was pretty much panned because of its based on the highest efficiency numbers which are hard to achieve in real life settings.
So I used several years of real life stats from my old battery system, 24v and using forklift cells and made a similar diagram,
With my latest 48v system using lithium cells its better at around 80%.
So folk have to factor in the loss if time shifting power from the grid in winter.

Handy to know Nowty, thank you for sharing that. All the more reason to do as much as possible in the go faster window.nowty wrote: ↑Wed Jul 13, 2022 5:10 pmDepends what your measuring.

Re: Camelot Members Annual Green Electric Generation
Charlie speaks about flats, I know these systems get a bit of a pounding here yet.....
https://www.pv-magazine.com/2022/02/24/ ... %20balcony.
It seems quite an attractive idea? 'Right love, we're moving. Grab the solar!' Many millions live in flats and are locked out of easy access to solar PV. I still like these systems.
