    6.6 kWp system with an east west split.

    A total of 676 units generated in June.

    Not quite as good as last year, but no surprises as it was such an overcast month.

    That’s not right unfortunately. My Energy is excluding the self usage from PV. I’ve double-checked on my inverter versus My Energy. So that 'consumption' figure is what you bought from the grid.

    Here’s what I mean for my stats. Here's my inverter for last month:

    And My Energy has the same 227kWh ‘consumption’ in the mobile app. but excludes the 90kWh I self consumed. And the same for ’Generation' in the My Energy app. It's only partial - it's what my inverter shows I feed to the grid but excludes my self consumption.

    Guys, first full months numbers since install, best day 19th worst 25th. Also looking at the figures on our Energia account and the export and import KwH's match pretty closely but the import Euro figure is higher than what I have, not by much. Across the 23 days we were exporting its €15 more than when I work it out from the half hour consumption figures I can download from Energia, what am I missing?

    6.5kWp E/W in Greystones

    June production = 800kWh

    May was 776kWh, I thought June would be higher than it was as although there's a day less, the days are longer and you'd expect June to be sunnier.



  • Registered Users, Registered Users 2 Posts: 6,444 ✭✭✭championc


    May SHOULD be the highest month each year, due to the lower air temperatures. Hot air temps reduce efficiency. This years' May was crap.

    Even though it didnt feel it I did 10% better than predicted at 842 kWh (6.1 kWp South Facing)

    Tracking the past 3 years still a good bit behind 2022 but on par with last year, July will be dissapointing as well me feels 😥

    First time posting here as we only setup the app in mid June though the panels have been in since Feb.

    7.56kW system, equal EW split based in North Mayo

    754kWh generated (best day was 4th July with 39.1)

    395kWh consumed (201 from panels, 194 from grid)



  • Registered Users, Registered Users 2 Posts: 2,662 ✭✭✭bullit_dodger


    Not a bad July - pretty much matched PVGIS. (6.5Kwp split exactly E/W in South Dublin City)

    image.png

    That said, I can count the blue skies all day on one hand this year. Production has been "ok", but nearly every single time I wake up to a cloudless sky, it deteriorates during the afternoon etc. Today no exception. Sigh.

    Seems to be the pattern of the year unfortunately.

    7.8kWp south facing. All electric house.

    The final few days of the month saved it from being a shocker. 74 fewer kWh generated in the month versus June which had 1 day less, consumption up by 80kWh as well. The dip has started 🥲

    On the plus side €68 worth of credit has been added to my Flogas account bringing it up to a total of €200 worth of credit to the end of July. There's a bit more left to harvest before consumption and production cancel each other out in October.

    The month was down on comparison to all previous years July.

    Screenshot_20240801-070539.png

    2021 shows what it can be. The rest seem to be typical. Only one good day really, the end was ok.

    Screenshot_20240801-070954.png

    An increase in usage and the drop in generation, and I had to pay for July 😭

    Screenshot_20240801-070457.png

    That's 96% EV rate

    Screenshot_20240801-070830.png

    Now I can forget July, which was not as bad as my perception of it: Dark, wet and cloudy.

    For July:

    788kWh generated - 6.72kW system facing ESE in South Dublin.

    329kWh consumed.

    Very similar numbers to July 2023.

    In July, self-used 25.9% of electricity generated and fed in the other 584kWh (no battery).

    Since initial installation on March 7 2023, a total of 9.24MWh generated, 6.38MWh fed to grid, with a self-use ratio of approximately 31%.
