Is there an easy way to find out what the DNO will allow us to connect, we already have s 4kw array, would like to add more and a battery or two?
I'm told it's not the issue, apparently like it or not I simply cannot consume or draw from the batteries more than this 3.68kW because of potential of it going back to the grid.
Ah ok - really helpful, so think this is the inverter: https://www.givenergy.co.uk/pdf/Version 2.0/Hybrid Inverter Gen 2.pdf
So in summary (just to check I'm understanding):
- 2 x 5kW for solar - No - ie overkill (although not impossible I could install more panels in future, so might have a slight advantage)
- 2 x 5KW for overnight battery charging - Yes - increases the maximum amount I can store
- 2 x kw for discharge - Yes - we regularly use more than 4-5 kW so would allow the house to continue in a power cut (out of interest, what actually happens if I have, say a 3.6Kw discharge rate and house needs 5kW - does electricity trip?
So just to update I've just signed the forms for the following:
4kwh Solar
5.2 GivEnergy battery plus 3.6 Inveter.
Got the fella to throw in bird protection and paying £7582.
We bought a new caravan so budget dwindled a bit so this is more inline with the budget than to a higher spec.
Plan will be to add another battery in a few years when things settle down.
I'm happy with the spec and compromise with the budget we had.
Yes!! ... made it at last, 4 solar panels in the garden and a small battery setup(DIY)
Been trying to get my usage cost down below the standing charge@ 25p as an unreachable target.
Really feel for the people getting big bills but solar and a battery will help massively, even a small setup.
My months usage and cost,
So chuffed really with this.

I just got quotes from ScottishPower, after a phone call. From the discussion, looks like they gauge the size of roof by viewing on Google maps.
Quoting £4347 for 8 fitted solar panels. Looks like they're 390w each, so 3.1kW altogether, which seems relatively low compared to what I've read on here.
Comes up to £7,800 if also having an Alpha B3 5.8kWh battery, or £9,069 with a Sonnen 5kWh battery. There's a data sheet for the former, but not the latter, so you have to guess what the difference is, and whether the more expensive battery is worth it.
They also don't given any illustration of possible returns from it, so I don't feel as informed as I could!
I'm surprised at the prices. I'd expected higher from a big energy supplier. But then I suspect iot's a competitive price but for a lower sized / quality product.
Is there any tool out there for measuring a roof and estimating what panels could fit? I don't remember enough trig from school for this! Using google maps myself, the south facing slope of our roof is a trapezium, with lower length 11.75m and upper length 3.06m. Distance from outer edge to ridge is 4.21m (although all of this doesn't take account of the roof being on a slope of course - and I don't know the slope angle!)
When you create a new project put in your post code and it shows the image of your area, you zoom in on your roof there.Thank you! I couldn't find any way to use Google. But it did allow me to roughly create the rooftop and then place squares on panel size on it as a mock up.
Using that, I reckon it would be possible to fit 10 panels. A row of 5 with three above, all portrait, then 1 landscape on each end of the lower row.
What is odd about the Scottish Power quote is they asked me about my electricity usage, but then have given no illustrations on how much I could expect to generate, store, feed back, nothing.
Anyway, the next step is to find some local fitters for quotes. Anyone recommend a company in or near to Cheshire?
