    Finally broke 45kwh today after few 44.9kwh days

    Think that's my 7.92kwp south facing system maxed out with 5kw inverter.



  • Registered Users, Registered Users 2 Posts: 2,724 ✭✭✭ECO_Mental


    You should see a few more KWh before the 21st of June...don't think you'll hit 50 but maybe close enough

    6.1kWp south facing, South of Cork City



  • Registered Users, Registered Users 2 Posts: 3,211 ✭✭✭pureza


    highest here too 86kwh of which 33.52 was exported



  • Registered Users, Registered Users 2 Posts: 2,707 ✭✭✭bullit_dodger


    Can't remember the last time we'd 4 consecutive days with nearly the same yield. Red is today (below)

    We still have tomorrow and Friday, but I think it's finally breaking on Saturday according to the forecasts. Setting April up for a record month I think. Fingers crossed.

    The legendary March/April 22…would push it…we nearly had 2 weeks of this back then. But yeah potentially 4-5 days of cloudless skies is exceptional.

    Here is end of March 22 and first few day of April, it dipped for 3 days and then we got another 3 perfect days on the 7th 8th and 9th April 22 as well

    I got more energy in March 22 and April that I did in June that year…

    Had to go back and look at my records, We had decent weather up here but not what you had down south, Some nice curves, but for me this spell has blown it out of the water.

    Mine are only at 12 degrees though which works great in summer, not so much in winter this is my 2022 monthly totals.

    As for farm work, Im 2-3 weeks earlier coming in with the fertiliser for the barley this year vs 2022, (also want it in before the rain at the weekend!)

    Last year we didnt have anything in the ground until the end of april!

    Was going to post this in the "random Renewable thread", but it seems to have disappeared. LOL
    This is the next best thing I guess since it's "daily production" based.

    Suspect April will break this precentage they set in March.

    My best since install of 7.2 kWp has been 45kWh last summer. South facing 35deg roof, South Tipp I can only recall having one perfect cloudless day in that time, have had 5 in the last week and hitting 42kWh each of those. Nearly every time we get sun like this in summer there's a haze builds up, not sure why that's not happening now?

    It's April. Weather doesn't tend to haze up as much as this time of the year, it's not that hot out yet

    Night and day between last year:

    and this:

    Comparing against this time last year, April has been much better for solar.

    But, can anyone explain this:
    My system is about 3.4kWp, this time last year I was seeing it hit that peak (and getting over 3kW during the best part of the day) albeit with less consistency because clouds:

    Screenshot_20250411-104034.png

    This year, with no clouds all week, I'm not seeing anything higher than 2.8kW (it's been like this all week):

    Screenshot_20250411-104123.png

    Obviously that a nice curve, but is there something that can explain why the whole curve is lower throughout the day and not hitting the peak of 3.4kW?
    The sky is perfectly clear (not slight mists or fine clouds), could the panels be getting too hot and therefore losing efficiency? Are the panels dirty so are under producing (I haven't been able to get up to have a look)?
    Thoughts?

  • Registered Users, Registered Users 2 Posts: 6,015 ✭✭✭GhostInTheRuins


    The hotter the panels get the less they produce. In your first screenshot you have a load of dips where it got cloudy. That gave the panels a chance to cool down so when the sun came back out the panels were working more efficiently.

    Good explanation of it here -

    86.4kwh today,33 exported

    Feeling nice and green this month



  • Registered Users, Registered Users 2 Posts: 2,651 ✭✭✭SD_DRACULA


    Gotta fix those export figures, been doing 60-70kwh export almost every day this month 🤣



  • Registered Users, Registered Users 2, Paid Member Posts: 4,812 ✭✭✭...Ghost...


    Since adding 3.6kWp to my existing 5.22kWp, my Solis geneartion looks a bit mad. You can see the grid export exceeding what the generation of the 5.22kWp system is showing, because the 3.6kWp is throwing out the extra above the generation and house load. The dips during generation hours are when appliances are turned on, with the big dips being the electric shower. The 2-6am dip is my storage and EV charging, with the midnight to 2am slot being a battery dump.

    poor few days here but back up to speed today

    80.8kwh of which 9.92 was exported



  • Registered Users, Registered Users 2 Posts: 901 ✭✭✭Exiled Rebel


    Where in the country are you? I'm in the so-called sunny south east and generated a whopping 0.9kWh from a 7.8kWp array.

    Thankfully we're away this weekend so the house is only consuming 7 to 8kWh per day .... although it's annoying at the same time that the system is not making hay while we're away.



  • Registered Users, Registered Users 2 Posts: 481 ✭✭discostu1


    Very bad few days in Cork city as well. Today though is fab



  • Registered Users, Registered Users 2 Posts: 3,211 ✭✭✭pureza


    Arklow-south facing ground mounted 15kw system,sunny or bright much of yesterday

    Just shy of 28kwh so far today



  • Registered Users, Registered Users 2 Posts: 2,707 ✭✭✭bullit_dodger


    hmmm, what's going on there in the 1st bitmap. If I read that chart correctly, your solar output jumped to 5kw at 9pm (from 0w) and you started to charge your battery? Or is green the solar output? Which I guess would make sense. No labels makes it hard to say for sure, but then you were charging your battery? It's a bit confusing.
    (just curious)



  • Registered Users, Registered Users 2 Posts: 841 ✭✭✭JohnySwan


    Some day for it lads, best of the year for me in Cork anyway.



  • Registered Users, Registered Users 2 Posts: 19,170 ✭✭✭✭VinLieger


    Yup big day incoming will finally be topping 20kWh and not by a small margin



  • Registered Users, Registered Users 2 Posts: 151 ✭✭omeara1113


    21kwh so far today never get more than 25kwh with a split system on East West facing so 6 panel's on the front and 6 on the back



  • Registered Users, Registered Users 2 Posts: 1,043 ✭✭✭tommythecat


    Not the best day of the year for me but a good one. And pushes me over 400kwh for the month. If I get the same tomorrow I'll end up around 25kwh more than last April.

    4kwp South East facing PV System. 5.3kwh Weco battery. South Dublin City.
