    It was all over the place in Dublin…..up and down from 7Kw to 1kw and then back again!

    Still…..very solid production at the end of the day. Tomorrow looking a wee bit better too!

    Today looks pretty decent, but tomorrow if the forecast holds could be a nice record setter for Dublin.

    Longest day of the year to boot. Should be blue skies all day, though I've actually had better production on cool days with a (small) amount of cloud. Suspect the panels being cooler helps. I guess it's a trade off between temp and solar irradiance

    Hit 60kw yesterday. 20 South panels with 18kw battery. I think 70 might be possible today.

    Ohh the race is on! :-)

    The green line is today and the red bars last year. It's perhaps 50-100watts more at the same time slice during the day than my previous all time high (19/6/25)

    Keeping an eye on

    Cloud radar United Kingdom - High resolution satellite images | SAT24

    and hoping no clouds form inland as sometimes happens.

    Aside: Nice to see very little panel degradation in 12 months.

    Had been hoping for 50 today on my system - which has been up and running just less than a year. 49 is the best I've seen so far but it went a bit cloudy and hazy here (Dublin)

    Currently generating 2.7kW

    My experience over the last nearly 5 years is that in the middle of summer with the heat is a peak that you won't break and you will find it very early on.

    I've never broke 45kWh on my 6.1kWp system but in really May this year when we had that really cold northern breeze I was pushing maybe to over 46-47kWh but cloud cover came in.... My theoretical Max I reckon is about another 2-3 kWh but everything has to align and I've not got that yet in 5 years.

    Hot sunny clear day while good you will not max out you peak production on days like this. May with the colder weather is where it's at.

    6.1kWp south facing, South of Cork City

    i think he peak i'd seen was late july last year - probably not much cooler than today.

    our system was up and running fully on around the seventh of July.

    edit: just looked back - our best was the 10th July, so the day was not appreciably shorter than today.

    Sounds like you had 15-20 kWh clipped? We got 60.6 out of a 9.9 kWp system.

    definitely reckon i'd have gotten the 50 if it hadn't been for that cloud earlier. 7.92kW system.

    Yeah, it was the usual familiar story that localized clouds formed inland and the afternoon wasn't great.

    image.png

    Got a total of 49.4Kwh when I add in the few panels on the shed. It's rare that I break 50kwh, maybe 2-3 times a year with all time high of 52kwh as I recall.

    so my system is 1year old today, went live after around 1pm on the 26 June 2025.

    PVSol predicted 6088 kWh in 12 months.

    image.png

    my actual generation is 5991 kwh, so should break 6000 kwh. only 1.4% short, or 98.6% accurate, that's not a bad result.

    ours in also exactly a year; though for the first two weeks we were only operating on 8 of the 18 panels. that might have cost say 200 units? but as it stands, we've generated 6225kWh on a 7.92kW system.

    to explain that to my mother, i was able to tell her that it was enough to boil enough water for nearly a quarter of a million cups of tea.

    (it takes 0.12 kWh to bring 1l of water to the boil - 6.3MWh would boil ~52,000 litres of water. and you'd get 4 or 5 cups per litre.)

    1/4 of a million cups of tea. LOL - but your being silly, nobody has 1/4 of a million tea bags :-)

    On another note - this June could potentially be entering epic/legendary status. Like March '23 or May '25.

    I'm pretty much already at PVGIS and it's only June 26th. I'll break it today for sure and there's 4 days left and forecasts are good for the next wee while anyway for Dublin. Averages are up on last year by 3-4% and last June was in the very good bucket. Fingers crossed.

    The only limit is the length of your clothesline. You could be drying 100's of teabags this week.
