Renewables: "talking 'bout my generation"

I was looking at the stats on my inverter app when I saw something that surprised me.

Apparently my rooftop PV array has generated more electricity so far this year than it did in the whole of 2024. That's despite it only being mid-September, with an entire quarter of the year to go.

I know 2024 was a terrible year for PV, and 2025 has been above-average, but I hadn't realised that the difference was *that* big.

I just checked and it's the same for me, 2% more as at yesterday evening.

Being a latecomer to solar, unfortunately I do not have enough data to play this game, but thinking about it I'm not surprised.

From the data I do have, March, April and May were exceptional with over generation in August too. The amount of generation over and above PVGIS predictions in months March to August is roughly equal to the predicted generation for the remainder of the year, so I'm fairly confident that if I did have a full set of data (and assuming last years missing data was at the PVGIS average), then I too would be observing the same.

Generally we are lucky here if we generate 250  kWh October- February altogether. I’ve checked and every year since install we’ve hit PVGIS by end of September.

Just had a look at my generation meter and I'm at 39999.88 kWh since installation, so I'm now going to have to stand in the garage for the rest of the day to witness the 4 MWh milestone. So that's PVGIS met for the year.

Still got over a month and a half to the installation anniversary, so a reasonable chance of hitting the 1 MWh/kWp target.

4 MWh achieved!

I’m 7 kwh short of a milestone of 1.4MWh, maybe tomorrow

Yep, same here.

A much better than expected 1.9 Os, today. The black clouds on the forecast turned out to be the lighter shade, with even a glimpse of the sun, first thing.

1.17 O’s here today
