Solar panel production figures

You will have peaks close to or above you're installed capacity, the graphs simply don't catch the data often enough to see it. PV Output shows you had a peak of 7.2 kW at 14:45, I fully expect you've had a much higher peak.

Here's my daily graph,at first glance the highest peak looks to be 6861 Watts at 12:29, and then its all down hill.

If I zoom in though I can see that 13:38 actually has a higher peak of 8808 watts

Now look at the gauges running on Node Red, and I can see the days highest peak was 8912.8 Watts at 13:39 (it doesn't show the seconds).

The main graph shows the values roughly every 8 minutes, zoom in close enough and its every minute, but my code running on Node Red is comparing the values every 5 seconds, so its far more likely to capture that peak power moment. It will likely be the same for any other installation, the graphing will just misses the biggest peaks unless they occur at the exact moment the data is stored.

22.7kw total production today. Battery’s fully charged and towels all cleaned at 60c. Another free day

23.0 at 17.54

For the first day of the month we have made 17.80 all going into the battery's and house zero export so glad i went with 2 of the 9.5 battery's on the house system
one of them would not have kept up.
As said before i have a off grid system on my koi pond hear as well 2400w of panels on Hybrid inverter with 5kwh of battery that run's the pond 24/7 all year round winter it needs 70w to run and summer 200w to run day and night it has just be switched to summer as there is the power to run 200w constant now on it



System is split two string East/West
down in not so sunny Devon.
East 8x 420w panels 45 deg pitch
West 10x 420w panels 45 deg pitch
Givenergy Gen3 5kwh hybrid
2x 9.5 battery's
 
213.8 kWh for March 15.9% under the March estimate. 8.9% better than March 2023 though.

That's 4 months in a row below my installer estimates
Same for me but overall for the year I am above my installer estimates so it's still a win overall. I do lose a few kWh hours in winter due to trees blocking out the sun but even if I chopped them down it wouldn't be a massive increase so it's not really worthwhile.
 
15.1 generated and 8.2 exported.

It was cloudy until about 4pm so quite poor until that point.
 
35.3 kWh for us today, unexpected because the day before the forecast was for full cloud cover today. In the end we got some sunny spells.

Speaking of high spikes, we also had a new record on the PV side too.

Looking at the raw data, appears to be a 10,331 W peak. Quite a bit over our installed capacity too (9.46 kWp), but I won't complain!
