April 2024 :

610 kWh generated for me , 7.4kW system split east and west , Mayo.

629 for 2023

Best day 26th……35.2

Worst day 10th….4.8

385.7 kWh produced for month of April using 4.35kw on east and west of single storey extension compared to my first full month in December when it generated just 30 kWh.

2011

6.6 kWp with no battery and an east / west split.

Exactly 500 kWh for April

4.8 kwp in North Meath produced 512 kWh pretty happy with that.

Well down on last year….

Nearly 20% down on last May (which was pretty great in Dublin)

Still 624 kWh and another 212 kWh (off the shed) isn't to be snuff'd at, but only 93% of PVGIS. Hopefully June is more back on track for us all.

NinjaTruncs

519Kwh for the month, all of it exported.

The month was a bit disappointing only ~50Kwh better than April. 11 days yielded less than 10Kwh per day, and most of them were around ~7kwh or less. Hoping June can be better.

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

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

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.

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)

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

6.6 kWp system with an east west split.

Not quite as good as last year, but no surprises as it was such an overcast month.

That’s not right unfortunately. My Energy is excluding the self usage from PV. I’ve double-checked on my inverter versus My Energy. So that 'consumption' figure is what you bought from the grid.

Here’s what I mean for my stats. Here's my inverter for last month:

And My Energy has the same 227kWh ‘consumption’ in the mobile app. but excludes the 90kWh I self consumed. And the same for ’Generation' in the My Energy app. It's only partial - it's what my inverter shows I feed to the grid but excludes my self consumption.

Guys, first full months numbers since install, best day 19th worst 25th. Also looking at the figures on our Energia account and the export and import KwH's match pretty closely but the import Euro figure is higher than what I have, not by much. Across the 23 days we were exporting its €15 more than when I work it out from the half hour consumption figures I can download from Energia, what am I missing?
