3.3kWh . Galway, 6kW array SE/SW
11.3kwh in cork 👍 7.4kwh system
Jesus lads, I know it's winter, but met Eireann are reporting NEGATIVE solar radiation now - LOL.
So.. Sun briefly turns into a black hole?
17.4Kwh produced today from 8.3kw array south facing
That would be hard to beat I think, just under 12kwh produced from SE SW split of 7.4 In cork. Yesterday pretty much identical figures also

Folks;
Could I cadge some real world info please. I'm looking at installing a 7.8Kw system with a 5 Kw invertor and Eddi on a due south facing roof. What would a realistic annual output look like?
The sales guy is suggesting 7281 KW annual output and figures 33% home use and 67% to grid. Is this realistic?
Thanks in advance.
Put the system details in here. https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html
6300-6500kWh production is more likely.
% self use and to the grid will completely depend on your circumstances e.g. EV, working from home, and how many kWh you use per day. Without a battery you will have high export figures from April to Aug.
If you've absolutely no shading issues all year around, a roof with a 35 to 45 pitch, and it's an extraordinarily good year, you might get close to 7000kWh. 6000 to 6300 is a far more realistic annual output.
I’ve already done 6350kwh in 10 and a half months with a 7.47kwp SW system with a bit of shading in the mornings in winter. Installed on 10th Feb. Might do another 100-150 kWh between now and the 1st birthday of the system. So that would be 6500 for me in the first year. Give or take.
this is the year to date (the increase in consumption later in the year is me switching to heating the water during the 2-4 am boost time each night as it’s about the same / maybe slightly Cheeper than oil)
5.3 kw today from 4.3 kw system. North Leitrim .
6kW inverter, yeah?
3.7kWh . Galway, 6kW array SE/SW
Correct.
5.2kwh in cork today from a 7.4 system
1.6kwh in Cork to finish out the year. 3.62 mwh in total.
2.9kwh today to get to 6,001 kwh for the year. 8.8kwp, east/west. 45 degree pitch.
What's the difference? I'm quoted a 7.8Kw system with a 5Kw invertor, is a bigger invertor better?
Max on an NC6 is now a 5kW inverter, (technically its 25 amps, so 5.5- 5.75kW) but inverters dont come in that size.
Before may 2023 you could get a 6kW installed.
Just had my first full year of PV, total 7,254 kWh for 2023. 9.1Kw system east/west. Co Waterford.
247kwh for December and 3725kwh for the 6 months since installation. 8.3kw array south facing.
He will only have a 5kW one. People seriously underestimate the effect of clipping.
Bigger is always better when you've a large array.....Unfortunately, we've been hamstrung by bureaucracy, yet again, so 5kW is all that's allowed for a new connection now. Needless to say, whenever my 6kW inverter needs replacing, I'll be importing a replacement and installing it myself.
Nice result for December.

Would January usually beat December?
Definitely, it would be similar to November.
I hope so …
90 kWh in dec . 180 in nov
