    423 kwh this month. 3.24kw facing west



  • Registered Users Posts: 11,378 ✭✭✭✭ DrPhilG


    I'll chuck stats up soon, although I changed from 6.2 to 7.44kWp during the month so the comparisons to last year won't be worthwhile.

    That's nice @DrPhilG. 4 more 310W panels? Added to an existing string or a new one?

    We all need more. Much more. 😁

    11PM: 15kW o'clock!

    7kWp W Dublin. 20kWh battery

    Production: 878 - last year was 850 which is odd as last year's May was a much nicer month weather-wise

    Consumption: 738

    Import: 8 (as per Solis but real life is probably 30kwh or so, just from the daily trickle)

    Export: 171 (last year 435 but 5kwh battery at the time)

    Best day: 19th: 46

    Worst day: 17th: 9

    Car: 173

    Whats the size of your system, those are good numbers I don't think you have your details on the PVStats website.

    According the PVGIS-SARAH PV estimator May and June should be similar enough for my system its showing for June I should expect only maybe a 2% increase in production than May. I don't think you will see a 30% increase from May to June but I don't know your system and obviously we could have an exceptional dry clear month that could break records.

    I only added a 2.7kwp array a few weeks ago, it should contribute significantly, I'm up to about 10-11kwp now, all south facing in sunny south county Dublin 😁

    Added to existing south facing string. Its now maxed out with 13 panels. Might fit another 2 on the house if I ever find any more of the 310w floating around.

    Upping the 5kW inverter to 6kW next week.

    You got me thinking about this again and I had taken a meter read back on the 3rd March and one again on the 24th May (so a good long period) and my shelly reading was 1.1% different than my ESB meter. Also I don't know what hour of the day the meter read was taken so it could even be tighter. So going forward I might start using the Shelly for reporting PV production. If I do I have just gained an extra 50 kWh over the past 3 months ☺️ (about 2% different to the Solis web portal.

    Makes sense really because I use the ShlleyEM for all the rest of my energy metering and reporting so it will tie in with this.



  • Moderators, Category Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 60,496 CMod ✭✭✭✭ unkel


    Did you buy the inverter already? I heard solartricity are sold out of Solis, waiting for another batch from China to land in July. Also, is that a wise upgrade? Very little of the time will you actually produces over 5kW once you go to a 6kW inverter. The difference is marginal, worth probably only a fraction of the upgrade cost of the inverter?


    Mate just bought an as good as new 5kW Solis hybrid inverter for €600 with all the bits included even wifi dongle. Jealous as that would suit me perfectly too!

    11PM: 15kW o'clock!



  • Registered Users Posts: 11,378 ✭✭✭✭ DrPhilG


    Inverter has arrived so just waiting for the installer for the date. He said it's a very quick swap.


    I've been getting some clipping already with the bigger array, but also the other benefit is 5kW charge and discharge rate compared to 3.5 currently. I've exported a fair bit in the last week just because the panels were generating 6.5-7kW for long periods and the battery couldn't take all of the load.



  • Moderators, Category Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 60,496 CMod ✭✭✭✭ unkel


    Ah the charge / discharge makes a difference for sure. I was thinking of the Solis range and the 5kW and 6kW hybrid inverters both charge and discharge at 5kW max, so no difference between the two. Would you not just swap the units yourself? It's an easy DIY job. But I guess if your installer does it, it keeps you in their good books in case you need support from them in future.


    I'm limited myself to 3.2kW charge and discharge and I've near 11kwp of south facing, so even with my high base load, I've started to export a lot recently. And don't really want to micro manage. I guess a wifi new model Zappi might be ordered soon...

    8.16kwp facing 200° at 35° in the midlands

    989kWh produced, thought we would break the 1000kWh but yesterday let us down.

    705kWh consumed, had a few days away in the middle of the month so exporting a bit more than usual.

    110.2kWh to Eddi

    171.9kWh to Zappi

    Best day 54.8kWh

    Worst day 9.5kWh

    Most current bill (Monday) was for €89 which covers all transport and hot water as well, taking out standing charges then about €20.

    Forgot to do April stats so doing both in this post.


    April Stats

    6.2kWp (3.1 SE/3.1 SW (in reality probably more like 2.5 on SW as 2 panels impacted by chimney from around 11am), 7.2kWh battery (added 2.4 in April to the original 4.8 install), North Galway.

    Generation – 607.2kWh,

    Export – 112.6kWh

    Import – 811.1kWh (564.4kwh for zappi),

    Best day – 24th, 35.7kWh

    Worst day - 11th , 4.2kWh


    May Stats

    6.2kWp (3.1 SE/3.1 SW (in reality probably more like 2.5 on SW as 2 panels impacted by chimney from around 11am), 7.2kWh battery, North Galway.

    Generation – 726.6kWh,

    Export – 142.6kWh

    Import – 667.3kWh (638.4kwh for zappi),

    Best day – 28th, 38.9kWh (record high for my install!)

    Worst day - 1st , 9.3kWh

    Most of my import was for my EV for the month. Car is in use more and more (clocked over 3,000km this month) Disappointed to have exported so much...will have to live with it until the 2nd ICE car gets changed for EV down the road in a few years!

    860KW this month here with 150KW going to the eddi which I am using to boost in the morning for hot water instead of heating via gas.

    Didn't bother with the comparisons to last year, no point since the capacity increased considerably.

    Last year was way better for me every month so far so I don't bother either



  • Registered Users Posts: 11,378 ✭✭✭✭ DrPhilG


    Yeah last May was nuts. Even with the additional panels this year I didn't surpass the 2021 figures. Generated about 75kWh less.

    1.125 MW for June.


    Nice to break through the megawatt barrier for first time since adding the new string. System was down for two days with adding battery system so good return considering.

    Just looking at my numbers for June and its looking like its going to be below par month for me based on the PVGIS Sarah estimates. I need 60 kWh from today and tomorrow to get me above the estimate and these two days aren't looking great...neither is the next week

    Will certainly be below March April & Mays numbers
