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

THE ALM

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.

ECO_Mental

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:

blue note

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.

A very good month.

All electric house, I'm genuinely surprised how little we've consumed (new house, built to passive standard).

bullit_dodger

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

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
