Since installation in Dec on the day before FIT deadline (!), we've generated 117 units in N Cheshire on an approx 42deg (est) roof with a 2.98kWp system facing approx 220deg (40 on pvgis)
I visited the loft around Christmas time (wonder why!) and I seem to recall that we were on about 22 units then, so I estimate about 90-95 in Jan.
Looking forward to seeing what today brought - lovely sunshine all day long!

it's 15º from azimuth (which they take as south), which they take as 0º.
it's not a compass bearing.
they take south as 0º, cos you'd be hard pushed to find the sun to the north in the uk anytime of year
Yes, that's well explained on the site - though it would be simpler for all concerned to have 0deg as North, and then just do the maths behind the scenes.
Actually, I just tried using their Africa map with a location of cape town. If you use either 180 or 0 you get the same answer. At my house, if you put 180deg you get about 1470 and with 0deg 2640.

11.1kWh here in sunny cider country, best day for generation since 1st November. Give it a couple of months and the daily average should be over 10kWh according to our PVGIS estimate :beer:Cider Country Solar PV generator: 3.7kWp Enfinity system on unshaded SE (-36deg azimuth) & 45deg roof0 -
What a difference the weather makes at this time of year
Surely the weather makes quite a difference any time of year?

That is off the genny meter - that's in the loft too! Can't read it off the inverter when I get home from work as its shut down by then.
8kWh today - I've not done a daily read before, but given that that's brought it up to 125kWh from 117kWh since mid December I reckon that's definitely been the best day yet!

:rotfl:
Yesterday we generated 12.12kW (best yet since Dec install); the day before it was 0.49kW (worst yet) so I agree with phsci - at this time of year the weather has made a big difference from 1 day to the other. However it remains for me to see what a dull day in June vs. long sunny day will bring!
We're also in N Cheshire, so hello to presumably nearby larkim & phsci.

Frodsham, if you're interested, phsci / barter.0
