the last day wasn’t great. So
Just shy of the 800kwh. I guess the people with low consumption numbers don’t have an EV or kids in the house, our consumption is generally over 1MWh per month
I think it would help a lot if people can add where you are along with the config they are running. Not to call out Ted above, but it's hard to tell if 789kWh is good or not as we don't know if he has 6kwp of panels or 10kwp of panels, etc
Are they all south facing? Maybe they are East/West. Is he in Killarney or Kilkenny etc.
Makes it a lot easier to spot performance issues for people if they can see someone with a similar system down the road getting a totally different number. Thanks
(800kwh for April is pretty good)
April.
Production : 760.77
Consumption: 218.83

From grid: 98.44.
55% From solar.
20 panels Meath.
I usually do five the details. South Dublin , 6.3 kwp system
6 panels SE, 8 panels SW
Nice one, in that case with 6.3Kwp….that's a pretty sweet result. For context, I just beat you with 864Kwh but I was working off a total of 8.8Kwp…
i've a 7,9kW system but possibly unusual in that i have it spread across three aspects?
Nearly forgot
This April on the left, April 2025 on the right
945 for the month. 7.9kW system with three aspects in Dublin.
914 for the month 7.9 kw 13 panels SE

Not a great May
1.025 MWh.
8.8Kwp south west facing Waterford. No previous year comparison

Kildare, south- facing
Newly installed since January so no comparison
903kWh, down 17% on May 2025
Pretty solid (106% of PvGIS) - like everyone, I'm 16% down on last year's epic May. <Will we see it's like again?>
6.5kwp in South Dublin City.
Shed chipped in with 277kWh, bringing the total up to 992Kwh. Sadly didn't break the 1mWh…..

May 2026: 896 kWh from a 8.02kWp system in Clare. Third highest month since install in Feb 2025, behind May 2025 (1.09 mWh) and April 2025 (912 kWh).
Record daily production 50.45 kWh on 24 May beating 21 May 2025 (50.12 kWh). I avoided clipping on the new record and benefited by around 2.7 kWh whereas the previous high was clipped for almost 4 hours.
I put this May in the same category as 2024. Shame Pinergy plan is gone.

Have you done your own app to analyse your monthly data to see which is the best tariff... Good job of you have.. Or what app are you using. I was planning to do something similar myself and just started it before I went on holidays.
5.6kwp e/w cork
I have. It's a long time in the android app store. 'Eco power optimiser'. Working on a new UI. Was stuck insulating the attic for the winter. Feedback was great functionally, crap UX. Still in alpha testing, but Claude is quick. Open source:
@curioustony that's cool, I might have a look at it when I get back from me holliers in 2 weeks..I have the early stages of a local python program on my laptop... Pull my sensor data down from HA then do this complex analysis anytime I want to make sure I'm on the best tariff etc. look into dynamic tariffs as well. (Even though I know they are ****!) Totally vibe coded with Gemini 🫣
For May:
863kWh generated - 6.72kW system facing ESE in South Dublin.
361kWh consumed.
Generation up on May 2025 (822kWh) and May 2024 (778kWh), down on May 2023 (881kWh - my best month ever).
In May, self-used 27% of electricity generated and fed in the other 625kWh (no battery).
Since initial installation on March 7 2023, a total of 27.5MWh generated, 18.89MWh fed to grid, with a self-use ratio of approximately 31%.
Installed on 14th May 2026 so first month in and getting used to it all!
10.8Kw system facing south in Waterford.
881kWh generated
855kw for me down 22% on last year.
