    May was poor in Roscommon too, the worst since (my) records began

    Last year the Net was ~€50, this year even with 97.3% EV rate, just under half that

    These 'good' months are needed to build up the winter reserve.

    Figures should really say for the Month.

    Solis alone last year was 1085.40kWh, really was a great May in '23.

    Prediction for Solis was 890.40kWh and Hoymiles 201.50kWh so not far off overall.

    Totally average month….exactly as predicted by the models. Nothing to moan about but nothing to cheer about either.

    6.1 kWp system just south of cork city

    Let's remember that the end of May and the beginning of June last year set a record for many, I believe. Here is my moving 7-day average for the past two years. I'm currently averaging 31 kWh/day over the last week.

    I've a 4.3kw system, south facing in north Dublin. I got 597kw system last month.

    I'm delighted with it, from reading this thread I really seem to be getting the max out of it. And I also seem to use less energy than most too - the highest usage I've had is 400kw and lowest less than 300. Where are all you guys using your energy? Electric cars and heat pumps?

    The other thing I'm delighted with is that I've an old meter. It runs backwards when I'm producing more than I'm using. In may I imported 96 and exported 400.



  • Registered Users Posts: 6,435 ✭✭✭con747


    Make sure you never submit a lower reading than your last meter reading. Always add a few units on. Have a read of this thread.

    Pretty solid month to be fair.

    A little bit off last years June (which was stellar), but 105.7% of PVGIS is always nice to get. Only one poor day in June (June 25th)

    Strange weather for June. I think the chill helped the early days, and the last few were a washout.

    As with May, negative bill, but obviously not as good as last year. That extra 67kWh last year was all surplus.

    Raw numbers for June:

    And the use buy mix is as good as I can get it, without further investment
