    I am getting results similar to those cloudless days at the end of March.

    I think it is a mixture of the height of the sun relative to 30 degree roof, the SE orientation, dust on the panels(?), Misty mornings, London smog in the air and the higher panel temperatures.

    But today my 3.6 system, previously generating a sustained 2.9 at noon, has been over 3.0 kW for about 2.5 hours today so I am hoping for a record.

    Nothing like an easterly breeze for sending that carp hanging in the air over London, back were it belongs (Poisoning the people around LHR ?).
    25.3:j

    30th April was the previous record at 24.4

    There were some small clouds today, but not many. I reckon Eric got bang on 27kWh today :)

    Close - but no cigar.

    Definitely 'haze' around again. Just been out and the distant hills were rather blurry.

    Tantalisingly close to the 30 Apr all-time record - 12.87kWh vs 12.92 kWh (2kWp system). I depollinated and de-birdmucked the panels this afternoon so hope for better tomorrow!

    Well if my system is going to hit max, today's the day. Weather forecast is for solid suns right through to 3pm, then some light cloud moving in.

    With an ESE system I can get 700W+ after 3pm if there's a little cloud, but the last few days I've been seeing as little as 100W as the sky is too clear to bounce anything back down. Great generation of 20 to 22, but missing out on those last possible 2 or 3 units in the afternoon.

    I hope their piece of lucky seaweed is working today.

    Watt hours, please!
    Mine was down by just 30Wh, hence my rash overestimation of my neighbour's production :)

    Watt hours, please!

    Lol, 60Wh, I failed on a technicality and being an electrician who knows the difference between watts and watt hours I feel ashamed!
    Maybe I'll just put it down to too much sun and long may it continue :j
