0.09, rubbish end to the year.
Total generation for December 51.1kWh, bit short of PVGIS prediction of 72.6kWh4.29kWp Solar system, 45/55 South/West split in cloudy rainy Cumbria.3 -
Best day of the last 15 = 0.5 O's today😄
December total 43.5 kWh, worst month....ever.🤬
2021 total 3466.6 kWh. 3rd worst year of the last 10!🤔16 Sanyo Hit 250s.4kWp SMA 3.8kWp inverter. SW roof. 28° pitch. Minimal shade. Nov 2011 install. Hybrid car. Ripple Kirk Hill. N.E Lincs Coast.6 -

Best day in eight here, better late than never! 0.85 O's, marginally above average for Dec which returned a meagre 69% of pvgis and in turn finishing the year at 96.7%. Poorest year since install in 2018, but 96.7% better than having no PV at all.East coast, lat 51.97. 8.26kw SSE, 23° pitch + 0.59kw WSW vertical. Nissan Leaf plus Zappi charger and 2 x ASHP's.

A decent 0.97 O’s here, the 6th best day of the month. Full stats tomorrow - happy new year everyone! 🍺Solar install Aug 2021, Lancashire

Looks like of the 51kWh generated I exported 16kWh which gives me a self use percentage of 59%
I thought that would be a little higher considering some of the really low generation days where I must have used 99% of it.
With that in mind, 35kWh * 20p = a saving of £7

After an awful December an encouraging start to '22 with 0.82 O's, so approaching mediocre.East coast, lat 51.97. 8.26kw SSE, 23° pitch + 0.59kw WSW vertical.

Best day of January and would you believe the best day of the year!3.795 kWp Solar PV System. Capital of the Wolds5 -
Decent start here as well with 0.77 O’s and a few sunny few days to look forward to.
December saw 76.5 kW generated, 87% of my PVGI target. 62% of this was used, 36% to the battery and 2% exported.
Total import from the grid - 631kW
Total export - 2kW
Average price paid = 6.4p per Kw.
Using my 15.78p peak rate my solar has saved me £7.48 and my battery has saved me £42 in its first month. This is based on the actual discharge amount.Solar install Aug 2021, Lancashire
