Im at 73.8kwh for december so far….but the last 5 days as only yielded 5.3kwhs

92.47 kwh for December hoping for magic 100.

Ive got this to see what i might be able to produce each month…..its got 81kwh for december, which im pretty close to already

Cars and turned on all the electric UFH... And general Christmas usage of ovens etc!

I wouldnt show up on a usage table compared to these guys…we only use between 4 and 5kwhs a day here lol.
I mean i was exporting off 350watts of solar production yesterday lol

That is outstanding mate! Although you might have got away with a flat pack kit or portable off-grid if your use is always really low.
I have conditioned the use OK managing the consumption overall, although you can tell when the wife is off work days for example as the import use is blatantly matching them days!

Not easy connecting all that to the house for the export gains though…..will add a battery next year and see how much more money we can save from grid importThat is outstanding mate! Although you might have got away with a flat pack kit or portable off-grid if your use is always really low.

0.8 kWh today.
Used a ton of energy today as well, has the oven running 5 hours, underfloor heating on, oh well don't do it often

The solar saddo that I am, I have crunched the figures above against my predicted monthly targets. I am assuming the same overall output for the year.Ive got this to see what i might be able to produce each month…..its got 81kwh for december, which im pretty close to already

What sticks out is the higher predictions for July and August. I think this is the result of using theoretical predictions against actual data. In real life, my panels like myself, have lower energy levels when it is hot (July) or even hotter (August). The one thing I do remember, when I collected my data from Germany in 2011, is that solar output is significantly higher in the 3 months prior to the summer solstice than the 3 months following. If this is because of the higher ambient temperatures it would explain quite a lot.
Good luck with getting 97kw this month.
Domestic is out of bed so I need to be good.....................

@Peteronthesouthcoast Thats what I see, second quater is normally the best quarter, so April, May and June, although this year has had a much better third quarter, but still not as good as second quarter.
PS Looks like blue skies all day here, currently generating 1.05kw, need to put the dishwasher on soon.

del as the graph answered my question lol.

According to that chart I posted they are and perhaps for the very reason that Peter says, the panels are colder, so work better. According to the Met Office June is the sunniest month.
Here's all the 2016 to 2022 yearly charts.

Q2 looks like since the longest daylight hours are in June
If you compare May to July
April to Sept etc you get a far more equal although still skewed graph
Typically UK weather I feel is better in the spring than the autumn.
If we get bad weather for the season it seems to happen far more frequently in late summer than early. (He says as an allotmenteer)

Mega day incoming. Not sure we’ll get to 10.

BTW the impact of heat is detailed on your panels spec sheet
It is a number that you add or subtract from typically 20-25c, its not that much, but in effect a say 400w panel may perform like a 425w say at 5c and a 375w at 45c
Mine are 405w -0.37% per c (from 25) so 10 degrees higher would lose 3.7%

Its 81kwh this month…..97kwh next month (january), but even your own graph shows higher production for january than december, so its possible i will see the same.
