2.25 O's yesterday. The month was horrible until the last 14 days or so.. was down 6.91 kwh from September 2012...
Roll on October.... and waiting for leaves to fall
...
Hiya Shafeeq. I had the opposite, Sept started off great, but the last two weeks were terrible. Kind of makes up for my micky taking back in July or was it August when S. Wales seemed to be doing better than many on here.
October has started of bad, and doesn't look like getting much better soon. Still, at least I've got one less tree than you now!
Mart.Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 28kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

September results: nearly 25% worse than last year Sunshine farming harvest is now marginally worse than 2012 though my harvest will be gathered in for another 5.5 months.
[There has been a bumper harvest of oats in the uk this year, so get your oats the price has dropped 35%].

When the numbers are duplicated, I was away from home and so not able to read the generation meter; so averaged the result over the missing readings.
While people in other areas were getting good results, even in Sheffield; here in the Thames estuary, there was a tendancy for clouds or fog to hang in the air until 11:00 then haze over from 15:00.

This led me to compare the September figures for my own kit :Just to celebrate having three Septembers to compare :-
2011 : 356kWh
2012 : 353kWh
2013 : 325kWh
I guess you might call that a steady downward trend and forecast that I'll be generating next to nothing in Year 25 :eek:
OTOH, since the pvgis forecast is only 292 and all three figures were somewhere between 10 & 20 % above that I may postpone my laying awake worrying about it session for a few years yet :beer:
2011 : 362kWh
2012 : 363kWh
2013 : 323kWh
(PVGIS 272)
...and this has cheered me up a bit, particularly since I've only 80% of Eric's generating capacity...
though it takes a lot to cheer up

All right then, if we're comparing Septembers:
2011: 181.27 kWh
2013: 203.90 kWh
2013: 157.45 kWh
SAF PVGIS is 174 kWh. Some of those PVGIS figures seem rather low - I hope you're not using "classic" - if I did it would be only 153 kWh, which would artificially inflate my feel-good factor! 2kWp Solar PV - 10*200W Kioto, SMA Sunny Boy 2000HF, SSE facing, some shading in winter, 37° pitch, installed Jun-2011, inverter replaced Sep-2017 AND Feb-2022.0 -

Now you can see why I think the dratted Os are such a waste of space !
You may only have 80% of the kWp but you'll have at least 110% of the incident solar radiation because you're 200 miles South of me and probably another 110% because your panels are likely to be steeper than mine (nearly everyone's are) hence more efficient as Sun's angle drops.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

Being a respectable married man, waiting for my tax free allowance; mine cost me a damn site more than that....Now you can see why I think the dratted Os are such a waste of space !

Calm down Eric; I only did 0.84 O's today so you still have a higher number......
Shhhh, Eric is watching the weather forecast..look..
