You really beat May 2025 figure? That sounds odd as I'm down 15% on it and I'm also in south Dublin city. May 2025 was legendary. Perhaps your system didn't log all the data or something for May '25 ?

May - 1313kwh generated - 9.7kWp south facing system in Galway

Best day: May 9th - 71.43kWh

Worst day: May 21st - 12.58kWh

May is now my best month yet, with just June left until I'll have had solar for a year.

910kWh for May on 8.28kW. South facing in South Mayo. Best day 27th - 52 kWh generated as the system wasn't clipping.

Looking at the previous posts, it just goes to show those further East and South, really do well with a smaller amount of panels and offset SE/SW aspects.
