An introduction from SW Wales

Hi all

Welcome PH, if you are planning to stop here awhile then Nowty will be itching to add your power generation potential to the cumulative list. :)

Yes I’m expecting this as I’ve been lurking on this forum since early lockdown, so I know you even if I’m new to you.
I also lurked on ‘St Elsewhere’ quietly joining in 2019 to buy our wind turbine tower.

Off grid since……
Our current power system started life in 2010, highly budget constrained & has brewed & improved since then ;)
Since 2015 or so much of this has been greatly helped by unsolicited advice & inspiration gleaned at the old place :)

..You are shrouded in mystery sir

My guess is that the PH is "PHantom flan flinger :lol (a true lurker of old)
So I may have to refer to you as phff or similar.

‘@Ph. any idea how many kWh your wind turbine generates in an average year ?

The problem with estimating WT's is they are extremely variable depending on location’

My WT generates a modest 750-800kWh/yr, but as ~2/3 of that is Oct-Mar it makes a significant difference.

What do you estimate my solar might be? Then I’ll tell you what it really is!

3.5kW in SW wales would be around 3,500 kWh but your sig says various orientations which suggests less than ideal so I will guess 3,000 kWh.
15.2kW PV > 100MWh generated
Ripple 6.6kW Wind + 4.5kW PV > 19MWh generated
5 Other RE Coop's
105kWh EV storage
60kWh Home battery storage
40kWh Thermal storage
GSHP + A2A HP's
Rain water use > 490 m3

Not bad, & perhaps we’ll achieve closer in 2023, as an Ash tree causing significant winter shading of one array & having some impact on the others was dismantled in December. Another factor reducing generation is summer curtailment due to not wanting to overheat the house :oops: this is getting less now we have Daisy (the Zoe), & are getting better at using her battery to make space in the house one when she won’t be there to use as a dump.
Yet another may be that ~ 1.5kWp of panels are direct connected which only beats mppt in very poor conditions.

Anyway 2022 was our best year yet for solar @2846kWp with nothing changed since Jan 2020.

I forgot you were offgrid :oops: , or else I would have knocked another few hundred off. :lol:

Part of my system started life offgrid and I used to have significant curtailment in summer. I still do have curtailment at times even now because I cannot have my export limit increased.
