Hit the 1MW mark yesterday afternoon. Phenomenal month.

Megastreisand

Best month ever (system installed Feb '23) - previous best month was 1.33MWh in June '23. 9kWp coastal Northeast.

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).

bullit_dodger

Pretty solid month June to be fair. 6.5Kwp in South Dublin City split E/W. It was 111% of PVGIS, so we'll take that as a win.

Shed chipped in with 275kwh (2.3Kwp south exactly) , so a nice total of 1.01MWh combined. Always nice to break that megawatt hour mark! Only managed it a few times over the years. Building up a nice credit with Energia for the winter period!

I'm sure others have had decent returns like mine.

Megastreisand

1.09MWh for June 2025. It's actually worse than June last year -1.12MWh which has surprised me and is far short of the 1.33MWh of June 2023 which was my best month until May this year. Still nice to break the 1MWh barrier though, 9kWp E/W , coastal Northeast.

GhostInTheRuins

Decent month, although worse than May and April.

555kWhs on 4.4kwp

munsterfan2

766kwh, a little up on last year, for my 7.2kwh south facing in Meath

May and June 2025, North Roscommon with a 5kw inverter. I’ve got 20x440w panels on a SE facing roof. Just had the system installed in December so this is our first summer with solar power. June’s export percentage is probably higher than usual because we were away for 2 weeks. I’ve also got an EV which I charge at home.

For June:

852kWh generated - 6.72kW system facing ESE in South Dublin.

320kWh consumed.

Generation up compared to June 2024 (approx. 750kWh - internet down for a week so number not accurately recorded) and similar to June 2023 (854kWh).

In June, self-used 26% of electricity generated and fed in the other 630kWh (no battery).

Since initial installation on March 7 2023, a total of 18.09MWh generated, 12.56MWh fed to grid, with a self-use ratio of approximately 30.5%.

Had mine installed mid May 24 so June is the first month I can do a direct comparison..June 24 , 858kwh ...June 25 750kwh ... 15 panels South Facing , Western side of Cork City 5.5kwp.The last 6 days were very poor

Eddi- 35 kwh

Zappi- 180 kwh

16 amp Chargepoint- 110 kwh

Aircon- 74 kwh

Only had the system installed late May, so June is the first full month.

24 panels split 12E, 8W and 4S, 11Kwp, 16kWh of battery.

curioustony

Probably the worst a June for me, hard to tell as comparisons are not exact.

Still love the buy sell mix

And I'm really money, it's all about the FIT rate

ted1

not a full month. But I’ve had the system in 1 full week now

14 panels /6,3kw in south Dublin

6 panels facing south east

8 panels facing south west

total generation = 165 kWh

Total import =86kwh ( off peak. , mainly car)
Total export = 126kwh

Total consumption = 124kwh

Boards_Member

520 KWh in June and 23.7Kwh today BUT…i've reached 35MWh total generation now ! Good figure …
