Renewables: "talking 'bout my generation"

Netexporter

Slight improvement to 0.49 Os. Didn't see any of the forecast sunshine, just a lessening of the gloom.

Today was a good day for December (pretty close to my whole-year average:

6.8 kWh, 2.5 O's

That puts me on 77.4kWh for the month. Another O tomorrow and I'll hit the PVGIS target

Just wondering if you (like me) have gone with the 'gross' PVGIS estimate, and not allowed/subtracted anything for shade?

Yes, I've use the raw PVGIS numbers (including their default %age losses); I wanted to compare against the "ideal". And yes I do get shading late in the afternoon which csots me almost an hour of generation at this time of year.

Belated season’s greetings to all, I have been in Hospital since 1800 24th Dec so not much paying too much attention to the solar. It appears that today was sunny but ward on north side .  Have a preposterous 2026 , (not a typo 😎) and really best wishes for 26

Hope you are on road to recovery soon @debitcardmayhem

well we finally broke the single kWh barrier today - 0.21 O’s today.

happy new year to all for later - here’s hoping for a sun filled 2026 ☀️🌞🌅

Lovely, if frosty, morning but cloud rolled in from the sea just at peak generation time, so a slightly disappointing 1.6 Os.

2.65 Os today

25.68 Os for the month

981.02 Os for 2025 (817.72 in 2024).

Total bill for the year £276.88 including gas and both standing charges and VAT according to Home Assistant.

Finished December at 17.7% below PVGIS, which is good for me given shading, but the year as a whole was my best ever at 10.7% above PVGIS or 1042.52 Os. Given that it was the sunniest year ever recorded I guess that's not surprising but considering the panels are nearly 15 years old it's quite gratifying.

2.3 O's today, which is the second best day of December helping to 103% of PVGIS.  Pleased with that considering both Oct and Nov were below estimate.  Running at 117% of annual estimate.

Wishing DCM a swift recovery plus a Happy and Prosperous New Year to one and all.

After three consecutive duff days the last two returned enough to take us 2% ahead fo pvgis for the month, the fifth best Dec in eight. Overall best year since install just breaching the 10 MWh's for the first and possibly only time.

Rounded out the year with 2.23 O's giving 215.7kWh (29.94 O's; 108% PVGIS) of generation for the month of December.

Year end, 1080 O's for 2025

Happy new year everyone!
