Picked up a little, 25kwh now, battery 94%, car 70%
I reckon this is about the best way in knowing the short term future.

And play the sequence to see if there's a break in the clouds coming.
Was a bright early morning in the Midlands but then dark clouds rolled in around 9. Hard to make worthwhile early morning PV this time of the year. Improved around 11 and more blue than clouds now. Hopefully get the car back to 100%, full hot water and 4 washes done come 6
Another brutally over optimistic estimate for today... 37kwh my....
Since we started in Tuesday this week our old meter is today 4 units below what it was on Tuesday.
Solar is absolutely throwing out the kw's now at 90% capacity. Remarkable buzz from generating one's own electricity
..hmm buzz is probably an apt choice of words
15kWh yesterday, nothing exported, but did get a bit into the Eddi.
Consumption > production for September so far. Probably will balance out today as look nice and sunny this morning.
managed a whole 6.5Kwh today ..
Yeah is was September last year went I got power to the house and the PV system started running but it was late October before I started logging it 25/10/21 so I have a bit to go.
The Solis web is saying I have generated 6.78 MWh since installed so I have about 6 more weeks of production. Although I use Home Assistant and ShellyEMs to log my PV now and they give me a percent or two more kWhs per month as the frequency of sampling is seconds instead of minutes through the Solis web.
Too late, you've just jinx'd it 😂
Very healthy 23.6kWh today. Tomorrow looks OK, and Saturday is a cracker although I'll be out all day so going to need to run the battery to rock bottom before I go.
Getting 7Kwhr tomorrow might be close Jonathan. You've roughly a similar sized system to me (I've 5.3Kw split e/w) and currently I'm showing....
Hope you get it :-)
My system will be installed a year this coming Saturday, so hoping to generate the 7kWh tomorrow needed to crest 5MWh for the year. The PVGIS-SARAH2 estimate was 4.47MWh, so very happy with that from a 4.83kWp system.
@ECO_Mental your system went live around the same time (same day?), right?
It's temperature - in your case the rain lowering it. I experienced the same a couple of weeks after my install ( and plenty of times since ). Lots of people on here advised it but I contact my installers who told me the same. I then contacted Trina, the manufacturers, who also assured me temperature has a big impact on production.
Back on track. The bird poo thing does interest me since I live next to a crow rookery. Definitely in the nesting months I considered up and giving them a wash... but I didn't bother this year.
For sure next year I will do and see if I get a different result on average. Crows can leave very large splatters!
Maye for sure was my best month for high highs... think the crows had moved on by then tho.😜💩
Yeah 90-99% of it is temperature, We dont really get much dust build up (we dont go that long without rain/not much dust in the air...
Its on the spec sheet of every panel, Temperature goes up, output goes down,
My panels regularly clip in May and June, vs the hotter July & Aug (max ive seen on the really hot days was 5.5kW), Now as the temperatures drop outside, I should see some clipping again, although the days arent near as long as what we get in May.
Another note, This years been a lot different from last, March was exceptional, May June July nearly had all the same output.
Just variances in the weather we get.
Bye 🙄
It's a bit of both Chancer. Dust, bird crap, shading etc will affect production, but there's many people here on the forums who've been using solar for many years and while dust will affect it......the far more prevalent and influencing factor is panel temperature. If you want the technical reason for this it's

I don't typically get involved in slagging games, but as for anyone slagging you off, I think that's on you. Slave1 above was just mentioning that the only person who called you stupid was yourself where you said something like
"forget what I said, I'm stupid" -
and he was just mentioning that noone else thought that and gave you the right answer. People can be wrong (I'm wrong all the time), but the defensive nature is unwarranted man.
I'm adding back my comment:
After the rains, my panels have increased in power back to their original output when fitted in May.
Someone tried to tell me it was because the rain cooled the panels down 😂
While that might be a half decent explanation, it does not explain why the panels had full output in the early hot days, but the power decreased in time and as the panels became visibly dusty and covered in bird poo. Then it rained. The panels are shiny clean and the power went back up to their original output. What was irrelevant was the temperature, as it was not hot on the day before the rain, and it wasn't much different after.
So there we go. Proof that dust and bird poo does affect output.
And not forgetting that the supplier of my panels also reminded me the panels would occasionally need a clean to keep them at optimum output.
So as I stated before, don't call me stupid unless you can back up your own claims with proof.
So bored with this now. I came here for help and to add my own help to the forums, but it seems someone is out to get rid of me after only 8 posts. And a Moderator too.
Disgusting.
Bye
Charming.
Is there any way to block people on here?
Edit: Yes there is. All done.
Moderator or not, nastiness is really acceptable, and you should know better.
6.56kw of panels. ..I was quoted for 16 x 340s
But ended up getting greedy and went with a higher output panel 16 x 410s
Ticking over slowly now at 2kw/h
Sweet. What size did you get in the end? Lot more than I got in Dublin yesterday
Ended up with 15.5kw yesterday which was pleasing for day 1 of full production. We used no grid yesterday.
Not so confident today with our 583w output through the clouds
a) Your stupid assertion is your own
b) You seriously want to extrapolate a Sahara Desert study of sand dust impact on PV Generation into Ireland
It's been noted year for years that there will be a strong peak in generation immediately after rain has cooled down the panels during "Summer" months i.e. dark clouds and rain clear to sunburst = peak. This impact is much less in Winter/Spring as the panels have not gotten as hot during the day, hence April/May are the typical highest generation months

Seems I'm not so stupid after all.
Post deleted.
It wasn't the dust or bird poo, the heavy rain cooled down the panels thereby increasing panel voltage and in turn your kW generation
First day.
8.1kw so far at time of posting. Pretty good considering the terrible dull weather.
Every little helps
Obviously I don't know what I'm talking about.
The load shifting has begun early this year
2.8 on the 3rd, 28 on the 4th.
This country is nuts.
