Festive wishes all, on the upside at least we know the corner has been turned and days are getting longer

Yeah it seems to stay online for up to an hour after sunset, it shutdown at 16:55 yesterday. That's going by the info on Solarman so its likely the polling interval is being added too. edit. Just downloaded the detailed info and the inverter first reported in at 08:56 and last reported at 16:40

The sun is out today. Might even break 3kWh production! 😁

I did just about with a 4.2kwp array. 3.7kwh produced today a few nice sunny spells this afternoon.

Yesterday was the first decent day in over 2 weeks here in Cork..

Nice what sized system have you?

6.1 kWp but I am lucky in that I have got perfect aspect due south and an inclination of about 40deg, also no shadows anytime during the year. Only up and running since October but cant wait until the summer to see what she can really do...

tnegun · 27-12-2021 12:07pm

Wow that's very impressive when I saw your figures I thought it at to be at least 10kWp!

The 40 degree south facing slope is a real winner in the winter.

Flatter panels work better in the summer, but in the summer you'll have plenty of power anyway.

With the gloom gloom gloom in the Midlands my 7.4kWp could be 74kWp and it would still be no good, what good is a jump from 300w to 3kW, when it's gloom there's nothing that can be done

Output since early December:

DrPhilG · 27-12-2021 9:07pm

Miserable month here, only 41.5 so far. Including a record low of 0.2kwh

December last year ended up with 68.3kWh so I'll be way down this year.

ELCAT2009 · 28-12-2021 6:30pm

What a day today! 6.8kw...not bad for a week after the shortest day

4.6 kWh here today. Best day since the 8th.

DrPhilG · 28-12-2021 6:33pm

Sun finally returned to Donegal, 5.1kWh today.

Jonathan · 28-12-2021 6:54pm

6.1kWh here in Fingal. More importantly, broke the psychological 100kWh barrier for the month of December that seemed completely unachievable last week. Looks like it will be the first month since install that I'll come in under the EU PV GIS estimate (141kWh) too.

tnegun · 28-12-2021 8:19pm

Only managed .8kwh here(Kildare) today on a 4.2kWp install.

ECO_Mental · 31-12-2021 10:29am

Was hoping to get a few nice days to finish off the year but unfortunately didnt get that...only got 300watts yesterday and that was only the system idling at 20watts. Doesn't look like I'm going to do any better today either...looking forward to the summer and seeing what my system can do as I have it only up and running since October.

You must have great aspect as anything near/into double figures is great for Dec/Jan and you are peppered with them

6.1Kwh at this time of year is awesome. A meager 1.3Kw for me on the same day :-( I'm still super curious about your production though.

When the sun is shining, your 100% getting everything I'd expect you to get (and perhaps even more!!), but when it's grey an miserable out, your panels don't seem to work well with diffuse light. Since it's Dec31st I still have to technically plug in todays figures for Dec, but like Nov I'm probably going to beat the EU PV estimate by 5-6% or so.

The fact that your 40% off what the forecast says (and your only 10 miles or so away) the weather can't be -that- different. 40% is a lot. On the plus side, it's only on the drab crappy days that it seems lower than it should be. Still I do like a puzzle :-)
