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%!

Re: September Generation 2024
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.

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

Re: September Generation 2024
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.
