Solar panel production figures

I'm going to see how this summer goes and may consider getting another battery if it's a sensible thing to do.

Or get some AC installed - not that it really gets hot enough (we're a lizard family :D ).

AC was where the majority of my usage went last summer, was on from basically 1st July through to end of August

I'd love a full year of stats because peak generation per month is an interesting metric, as it should roughly follow a curve.

Here's mine so far (rounded down, so actual may be in that kWh somewhere):

September: 21 kWh
October: 18 kWH
November: 11 kWH
December: 8 kWh
January: 9 kWh

It's easy to see that in the peak of summer the generation on my end is likely to be in the 30 kWh range, maybe even into the 40's on some days. Temp will reduce efficiency though.

Can also see the shading coming in after October, the impact to the west facing panels is high.

Some of the generation curves would be interesting to see as obviously mine is very much starts slowly, hits a big peak and then tails off, where as you will get multiple peaks in the day I'm assuming.

Mines great, spot the shading.

July 43.08
Aug 40.65
Sep 28.43
Oct 21.75
Nov 7.87

Dec and January don't count as I only had it for 5 days in each month.

Crossover with South and West later in the afternoon and generation into the evening will be nicer.

I think ideal is having East, South, AND West facing panels tbh, nice and flat curve longer generation in the daylight hours.

But you need enough on each axis to cover the startup generation and such.

We're punching similar numbers on PVO. This is me from last year. I'd expect you to generate a little more over the summer months.

Thats good to see as I was sceptical on March being as high a jump as my model predicts, but looks like it really is.
Mine assumes 175 for Feb and 343 for March which seemed a big jump, but looks reasonable from your curve.

Yeah your November figures really drop off, mine do a bit as well I think but not as bad as yours do.

Shame, but at least Go exists and will still pull great numbers for most of the year when it matters the most.

Yeah our figures do seem close most of the time, so it will be interesting to see how this goes in the year as well.

As a general thing I'd love to get, per month, the following for each of us when 2023 ends:

Solar Generated Sum
Lowest
Avg
Max

Solar Peak
Lowest
Avg
Max

Not sure if anything else really matters, but that will help draw some conclusions about system at different points in the year.

how big is your system again??

The extra battery charge bit this morning isn't helping things, I've also been hitting capacity!

Washing machine on, usually the battery would have more headroom to charge into.

Yeah true, now I need to work out a way to add a reasonable allowance into my solar sheet for diverted elec
Going to have to be an estimate as I am not sure I cannot be bothered to read the diverter in the airing cupboard!

And true, had about 14% higher SOC when solar started to exceed usage compared to yesterday at that point.
