Solar panel production figures

So two days so far apart 6.50Kwh yesterday and 30.30Kwh today near five times as much anyhow despite the low battery's last night we made it and did not flatten them they got as low as 12% at 8am today before the solar picked up. So today we made 30.30Kwh used 12.40Kwh filed the two 9.5 battery's to 100% and exported 3.10Kwh
from the house.
The workshop made a bit under 11Kwh filled the battery's and exported 2kwh

House System is East West
down in not so sunny Devon.
East 8 x 420w panels 45 deg pitch
West 10 x 420w panels 45 deg pitch
Givenergy Gen3 5kwh hybrid
2 x 9.5 battery's

Workshop system is South/East
2440w of panels two 720w strings
one 1000w string
Hybrid inverter with 4x 12v 100Amp
Battery's
Plus grid tie inverter as well

Much better than yesterday.
Bit of a rough start, bright middle and dull and showery at the end.
32.4 generated, 16.5 exported

Interesting! We're not that far apart (a couple of miles at most) and yet my 18x 440w SW-facing panels produced 32.6kWh, only slightly more than your 15x 430w array. It makes me think mine have slightly underperformed and I'm curious as to why!

Your previous post says 38.58?
I've previously wondered if my system was underperforming compared to @JackRegan's system: "Den Perry did it"
I don't think there's any real explanation apart from changing weather clouds or something.
There have been days where Jack's system has generated more than mine despite being slightly smaller.
But overall, mine is performing slightly better as I overtook him in the PVoutput chart a short while ago.
I'm sure it won't be long before you're passing me.

This was my graph yesterday:

I have another 11 panels on my NW-facing roof. My other post says SW, when in fact those panels are SE. I was just comparing our south-ish panels rather than my overall system which did indeed do 38.58 in total :)

I guess a cloud might have been more over me than you - I'll probably get around to sending the individual roof data to PVOutput for interest purposes one day.
