Renewables: "talking 'bout my generation"

Was i the only one blighted by cloud today?

Managed 3 O's, all 3 systems doing roughly the same. Its just not fare..........

Best result for me was as posted earlier, 7.65 O's, like to think it'll happen again, not looking likely if you all keep passing your clouds my way!!!!

Nope! I got my fair share of clouds this afternoon. Glad I'm not on my own ( misery loves company) was starting to feel jealous of everyone having glorious sunshine all day;)

very strong!

What's the record for O's on here?

Like Kevin, my first thought was Jackie's system. I'm always astounded by it.

Hiya Jackie, I guess you've got just the right combination of factors, and a slightly undersized inverter to boot. But can I ask, are you anywhere near the sea?

Might seem like a silly question, but was following a thread recently on another forum about high achieving installs, and it was noted/discussed that cooling sea air, and possibly a little bit of reflection (that may have been an in-joke) could be the cause.

Never mind Dodo, there is always the morrow, I did say you would get the Hawaii the morrow.....

Cloud all afternoon....3.76 O's :mad: The morrow is the day....

Hi Mart (and Kevin, yes, I'm a 'she' )
We're about 10 miles from the east coast, not sure if that's close enough to benefit.
We do seem to be lucky with the weather here. We are at the top of a valley with a decent sized river at the bottom. It sounds odd but we often get slightly different weather here than happens all around us, for some reason bad weather often seems to divert away from/around the river valley.
There are several gardens around here that have palm trees growing in them
My generation meter only records whole kWh (but, I understand, retains the part unit in it' memory) my best ever days have registered 16kWh on the meter, (which is a fraction over 7.2 Os)

We are pretty happy with our system

groovyf

Got around 8kWh yesterday, with peak generation at some point during the day of 3kW - I guess that was just before the clouds rolled over

Hiya Jackie. Probably not close enough to the coast, so you must just have a system where all the plus points line up. No wonder you're pleased.

Another poster's system that springs to mind is Mysterons, though he doesn't post very often. I think he's just NW of London, so definitely not coastal. I recall his 2012 generation (from a 4kWp system) was 4,460kWh's, that's a mighty 1,115 Os (kwh/kWp). Presumably 2013 was even better?

My target of 761 Os (actual 791 in 2013) pales into insignificance, but I likes it anyway! Brawn over brains, or perhaps determination over commonsense.

Mart.

That's close to the sort of level several quotes suggested I might get but would be happy with 3,800Kwh+

My system :

1) SW based - not far from Bristol

2) 4Kw but capped to 3.68kw

3) Orientation -16.5deg SSE

4) Roof Inclination - 27%

5) Very light shading to SW - might impact a touch in Nov-Jan - estimated at 0.9%.

6) Panels - 16x REC 250PE-BLK

7) Inverter - Steca SG-3600

8) Inverter in loft - might cause problems on hot days.


No power optimisers but not sure I really needed it.


Looks to be performing very well so far but obviously very early days.

Technically should I base my O's on 4kw or 3.68?

1115 Os is a fantastic result!

We're Kent so not too far from Jackie but we also seem to get different weather from those around. We're about a mile from the estuary but with the downs very close by the weather can be very different even just driving 5 miles over the hill.

For 3kWp we got 3137kWh in 2013 and approx 3240kWh in 2012 (slight element of estimate as inverter out of action for short period)

Hiya Jim, it gets worse

Found a recent post of his, slightly different numbers as these relate to anniversaries of the install, not calendar years:

2010-2011 4419kwh
2011-2012 4228kwh
2012-2013 4421kwh

1,057 to 1,105 Os. Very similar to you - Cool. Jealous, moi, nah!

Hope he doesn't mind me talking about him, but very impressive results, and consistent too.

Mart.
