    2.85 O's yesterday. Got to 101% of April target (was at 116% at one point during the month)
    Last April was 94%
    Half way through the month and at 98%, and ahead of the same point last year.

    Interesting, we are Herts and WSW facing but we have got 105% and 110% last two years compared to your 94% and 101% - I wonder if we have something wrong with our PVGIS calc....
    I think....

    I have some shading during the morning due to a chimney, it's normally around 11.30 before the panels are shade free. That could explain the difference.
    I compared my generation to other posters last year during days in which we had sunshine all day and roughly calculated that I am probably losing 40 to 50 O's over the year.

    I also have a chimney (actually a gable) problem, though only in the early morning in June-August, when the sun rises considerably north of east. Because I have a Sunny Boy inverter, I've tried out SMA's Optitrac Global Peak software, and it really does work - though I've no idea how. I don't know if any other manufacturer supports anything similar, for I imagine Optitrac is system specific. If you run it all the time there is a slight degradation in overall output - the manufacturers quote 1%. I run it in the mid-summer months (when I remember to turn it on).and it gives me about 40% more generation before 9am (only when the sun is shining, of course, but there isn't a shading problem when the sun isn't out).

    3 Os today, but I'm glad to say it's turned into a wet bank holiday. We need the rain.

    2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.
    Reg. for FIT Nov 2011. "It's not what you generate; it's how you use it that matters". One very clean Vauxhall Diesel Sri, £30.00 Road Tax: B)

    Definition of 'O's = kWh/kWp (kWh = your daily & accurate Generation figure) (kWp = the rated output of your PV Panels).
