super_dad

likewise best month since install mid May 2023. 678 KwH from a roof mounted 4.1 Kwp directly south facing unit. Donegal based

CR 7

7.04kWp system installed and started generating on 7th May, 815 kWh total for May. South facing roof in Cork City.

Shame we missed out on the first week of May, there were a lot more cloudy days towards the end, so it could have been even better.

LowPowerMode

Managed to break the 1MWh barrier for the first time from a 7.8kWp system - after the amazing start to the month, made to sweat a little bit especially with the worst day of 8.7kWh on the 29th but generation picked up very well again for the last 2 days so ended up with 1048kWh for the month - best day was 48.9kWh on the 22nd.

CivilEx

7.0kWp ground mounted south facing - East Mayo, total of 1.1MWh, cracking month. Best day was 51kWh.

alfa_aficionado

What a month (May)…broke the 1MWh mark for the 1st time since system installed in Sep 2023. Managed to generate 1.295MWh and broke daily record 4 or 5 times over the month (daily record of 58.1kWh reached in the middle of May).
