My results for December were:

3.87 kWp, slope 50 degrees, due south, lat 57.15

Total generation: 60kWh

Daily average: 1.9kWh

Generation per kWp: 15.5kWh

Daily average per kWp: 0.49kWh

PVGIS: 62.1kWh

%PVGIS: 96%

2nd worst December (by 2kWh) since install in 2010, but best years production overall (159kWh above average).

20kWh from Solaredge system
25 kWh from Victron system
666kWh from WT1

I'll have to wait until back home to get the Victron year total but so far.
3,700 kWh Solaredge
4,639 kWh WT1
????? kwh Victron

Guaranteed over 10MWh (might squeak through 11MWh) clean power for the year 22 from our various bits n bobs.
Definitely a PB
A sense of dislocation to think that year 23 will be 14 to 15MWh with full year PV at max system size & WT1 full year too. The year beyond that 30MWh when Kirkhill is running.
At that point, we will be genuinely FF free.

This December I actually generated more than November, simply due to the 1.2kWp added to the wall of the house.
They've worked superbly, near doubling the generation this month.

236.4kWh here, probably quite indicative of how capped I am in summer.

6127 kWh for March - Dec.

Interesting to see how the output / weather varies around the country - I also have just over 61kWh for the month, but my PVGIS is only 45, so I was chuffed to be so far ahead of target - I always expect to be at the lower end of generation being 'up north'

Pretty much south south east, 35 degrees,

Total 228.5Kwh
Low 0.4Kwh
High 20.3Kwh
Average 7.4Kwh

38% consumed by house and EV
48% into Powerwall
14% back to grid for free! Stupid no feed in tariff for DIY install

Nowty Towers Power Station
Main 4kW PV system generated 136 kWh which is about 27% higher than baseline and my best Dec ever. (totally opposite to marshman not that far away)
Total PV arrays generated 237 kWh.

Electric Import was 1729 kWh.
Gas import was 11 kWh.
Out of house EV charging was 102 kWh.
Petrol used in EV hybrid was 0 kWh.

Total imported energy use 1842 kWh

Electric export was 14 kWh.
WT1 generated 770 kWh.
Total energy offset 784 kWh

Net energy for Nowty Towers > 1058 kWh

----------------------------------------------------------------------------------------------------------------

End of Year Review 2022
Electric Import was 9223 kWh.
Gas import was 330 kWh.
Out of house EV charging was 569 kWh.
Petrol used in EV hybrid was 191 kWh. (disclaimer - no data for first 3 months of year)

Total imported energy use 10313 kWh

Electric export was 1135 kWh.
WT1 generated 5335 kWh.
Total energy offset 6470 kWh

Net energy for Nowty Towers > 3843 kWh

By the end of 2023 year net energy should be lower with a full year of WT1 generation.
By the end of 2024 it should be negative with WT2 generation even if it’s a bit late to the party.
By the end of 202x it should be even more negative when project 3 goes live.

Will that offset our meat diet and holidays ?, I don't know, will have to keep calculating and offset or cut down as appropriate.
