I would say May wasn't great but…
4.8SE 3.2NW Cavan
Generation May 2024 789kWh May 2023 897kWh
all nominal as NASA would say!
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.
An average of 16.46kWh per day
Last years May was better - 780kWh
this year May 655kWh

Not great. Hoping for a far better June, July and August than last year!

My first May was OK. Up from 666kWh in April.
1st May here since PV installed.
Smart meter installed from 4th May - 127kWh generated over the 3 days prior to this!
All time high yesterday of 56.6kWh from 9.1kWp system in the Northwest.
7.4Kw Split East /West Mayo
total for Month of May. 679Kwh (2023 had a yeild of 881Kwh )
Best day :10th 39.9

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.
For the last bi-monthly bill (27/03-27/05) we exported 1,213.879 units at €-0.24 per unit for €291.33CR

First May for me in Sligo.
4.35kwp, 5 east and 5 west on the lower extension of a two storey house. Shaded for most part in winter months and also miss the early morning sun because of neighbouring trees.
457kwh in total for May.
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.

May 2024 - 6.5kW system (Wicklow E/W) with a 5kWh battery:
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.
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.
Ah no. I'll have a read.

10.75kwp East Cork.
A very good month.
All electric house, I'm genuinely surprised how little we've consumed (new house, built to passive standard).
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)
978 Kwh generated for June. System was down for 8 days at start of month for moving to new shed so all things considered not the worst month
My Setup:
7.74kW (18x 430w panels) 9 panels South / 9 panels West in North Waterford, slope 40°, 5kW Huawei Inverter with No Battery

Actual Generation 887.99 kWh (101% of predicted) first time since the panels were installed just over 12 months ago that I've hit the predicted targets, well happy with that :)

Best Day 23rd Jun- 45.99 kWh
Worst Day 29th Jun- 11.68 kWh
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
