The sun came bursting out around lunchtime so managed 5.2 today, which is probably about the highest all month!

Evening all
I've made a crude excel doc trying to keep tabs of the £ +/- in our first year with solar.
Has anyone made similar that'd you'd be willing to share?
Or perhaps take a look at mine?
I have 17 panels split 7x SE and 10x SW. 3.6kW inverter and 5.12kWh storage.

I think I can call this year at:
4053Kwh generated, about 20% more than I was quoted. May and June were bumper months with over 650 KWh generated each.
4.4 kw array 50:50 SW/SE, GivEnergy gen 1 3.6kw hybrid with 8.2 KWh battery.
If electric stays at this level I should brake even in approximately 15 months, approximately 4 years total.
Even in December my electric bill is only £50 (inc standing charge) taking into account the saving sessions.

Managed 1.2 today so my 60 for the month is now not baked in at all, yikes!
When I posted that yesterday I thought I had an extra day, forgot it was the 30th today.
So tomorrow I need 1.3 for the "magic 60"
What a shockingly bad December.

A whole 0.39kWh today.
Up to 82.2kWh for the month. Tomorrow may have some sun so we might be able to hit 85, but I doubt it.

Today 2.5, tomorrow forecast for 3.5.
Currently on 126 kWh was hoping to get to 130 for the month.

I can't even remember what my solar panels are supposed to do.

A bad day only 0.30kwh generated and ran out of juice in the battery during peak 4-7pm as wife had tumble dryer, washing machine and dishwasher going-grrr

Awful wind lately, gales and buckets of rain. Cleanest panels just no sun. 0.7kWh today.

And the scores are in.
Dec 60.4 vs target 90.5
2023 4426.6 vs target 3892.9

SolarEdge generation.
So not the worse December, or the worse year, but the second worse on both counts.
Total system generation for today is 3.7 kWh, for the month is 130 kWh, and for the year is 8302 kWh.
In 2016 and 2019 I almost generated as much power in December from just the 4KW array!
| December Generation | Years Generation | |
| 2016 | 121.929 kWh | 4360 kWh |
| 2017 | 106.152 kWh | 4390 kWh |
| 2018 | 103.204 kWh | 4370 kWh |
| 2019 | 120.814 kWh | 4380 kWh |
| 2020 | 95.216 kWh | 4510 kWh |
| 2021 | 71.08 kWh | 4150 kWh |
| 2022 | 83.514 kWh | 4630 kWh |
| 2023 | 76.884 kWh | 4290 kWh |
