A poor month:
231.5 kWh from our W-facing panels, 82% of the supplier's prediction. Previous worst was May at 87%, everything else has been 90% and above. June was 99%!

221.4 from 3.43 - 265.2 pgvis so 83.3%

345kWh from the main Sunsynk system - below the 368kWh PVGIS, and lowest so far by a few kWh
86kWh from the Hoymiles mancave system

Nowty Towers Power Station (self operating this month)
Main 4kW PV system generated ??? kWh (dont know until I get home)
Total PV arrays generated around 900 kWh (dont know actual number until I get home).

Electric Import was 537 kWh.
Gas import was 0 kWh.
Out of house EV charging was 1131 kWh (circa 4000 miles of Euro driving ).
Petrol used in EV hybrid was 0 kWh.
Total imported energy use 1668 kWh

Solar PV / Battery electric export was 1022 kWh.
Ripple GF wind farm generated 842 kWh.
Ripple KH wind farm generated 466 kWh.
Total energy offset 2330 kWh.

Net energy import/export (this month) for Nowty Towers 662 kWh

Net Energy Import/export (cumulative this year 2024) for Nowty Towers 9061 kWh

Poor month for me, not surprised given all the miserable weather days here.

Main 4kw FIT system = 330
Sunsynk system = 185.3

September was a poor month vs 2023, 200kWh less generation compared to last year!

Anyway here are the scores on the doors

System production - 743kWh
Self-consumption - 537kWh (72%)
Export - 205kWh (28%)

Overall building consumption - 2.17MWh
Import - 2.17MWh (80%)
Self-consumption 537kWh (20%)

Interestingly with our switch to the Shape Shifters Tariff, we're saving about £160/month because of the lower daytime (and overnight) rates.

[Joeboy]

Solaredge PV 298kWh
Victron PV 395kWh
Enphase PV WS 34kWh
Enphase PV HT 6.4kWh
Hoymiles PV FS 45kWh
No1's Hoymiles PV 59kWh
Graig Fatha WT 529kWh
Kirkhill WT 820kWh

2,186kWh RE generation minus 59kWh No1's Hoymiles = 2,127kWh personal RE generation.

Cash
£69.51 off the WT's
£60.88 off the Octopus export

£130 smackeroo's into the VB. Happy with that.

Now that the system is pretty much maxxed out here I'll track the change across the months until Derril comes online.

WT/PV split
Aug 57.5%/42.5% total 2,753kWh
Sept 63.4%/36.6% total 2,127kWh

East/West system - 6.56 kWp
September PVGIS (11% loss) = 469 kWh
2023 = 419 kWh (89% PVGIS)
2024 = 356 kWh (76% PVGIS).

This September has been grim in the East Midlands, the Met Office have recorded 78% of average sunshine hours and the 2nd highest September rainfall in their records (1918 was the highest).

Helped by 92 kWh from the 2.25 kWp South vertical system added this year, though this was the lowest month yet with all previous 5 whole months being over 100 kWh.
Though there were 2 good days, the 16th provided 8.6 kWh and the 17th 8.4 kWh, the highest single day values from the South vertical system. The lower trajectory of the sun is aligning better with the vertical mounted panels. We just need more hours of sunshine.

At last some sunshine today.
