Solar panel production figures

Nearly beat you, 2.37kWh but no export to speak of, I need the batteries for tonight.
Very close, but look at you're efficiency, almost 3 times mine.
My batteries at 35%, when I export I stop at 55% now, then when I charge off peak its enough to get it to pretty much 100% by 5am.

yup it went pretty dark, pretty quick just now, but nothing happened.....back to 5/600 watts nowYou're now thirteenth, but I'm third from the bottom not counting Maplewood
Any advice on Solar options for my use case?
Calculated my annual usage from my last 12 months of bills, it's a scary 12500kWh apparently (BG still has ~5000kWh as my annual estimate despite fairly consistent readings).
My roof is fairly large, but East/West facing. I have a small area which is south facing but is blocked by the main roof until mid-morning.
Assuming I want to maximize my usage of solar (panels, batteries, minimal draw from the grid and only at night), what's the view on # of panels I should be considering and capacity of batteries?
If it makes a difference, my day time usage is averaged at 8 (summer) - 12 (winter) and night time average is about 2.5 year round (so daily usage 10.5-14.5kWh, if my math is correct?)

12500kWh is gas? Your BG estimate of 5000kWh is pretty close to your 14kWh a day usage for electricity.
East/West is viable. Its less spikey than pure south so you generate throughout the day, I'd max out those roof spaces and possibly the small south facing area, the installer can advice on shading issues, they can fit optimisers if needed.
Proper thread here https://forums.overclockers.co.uk/t...y-real-world-reccomendations.18946524/page-89
My Gas annual estimate is 19000kWh.... I haven't added up the figures to check!
Thanks for the link, I'll have a look

The rains stopped, and it's much brighter, currently generating 2.7kW
PS. You're behind me now
it was only a matter of time...rains hit us now, so thats probably it for the day here.How accurate are generation meters? I popped up into the loft today and decided to read it (why they put it there I don't know) and we've apparently generated 276kWh in the last 24 days according to that.
My figures based on the Fox portal suggest only 91kWh in the same time. Its been giving me some very low daily results recently (as seen on here like the 0.1kWh yesterday), so I have strong feeling that charging from the grid at 0200-0500 and the resultant losses are throwing the figures off massively. Until I started charging early in the morning it was around 5% out.
