    21.1kWh today and 23.1kWh yesterday, nudging the 7 day rolling average to 20.4kWh, which is only 0.4kWh below it's record on 28/5.

    We're only 0.5% below the July PVGIS target pro-rata despite a terrible start to the month. :beer:

    That easily beats my 12.59 kWh for a 3.92 kWp system. Shafeeq did even worse a little further north.

    Found this local private weather station that may give him some prior warning on what to expect.

    Very suprised at the variations within this thread; in my situation, I do badly until 10:00, in clear cloudless sky, than I do when there is thin, hazy cloud cover. So many anomalies, fascinating.:) UV for him at present is showing 0. :mad:

    That's because thin clouds reflect some solar radiation in the direction of your panels boosting the output, whereas cloudless skies can't (as much). In layman's terms, you can think of clouds as very weak mirrors which can bounce sunlight onto your panels when they are otherwise not in direct sunlight. Of course clouds also reduce radiation when they cast a shadow on your panels.

    I'm guessing you don't get direct sunlight on the panels until 10am?

    That is correct...my graph today shows more gen before 10:00 (not enough to get excited over) than it has in the past three days or so. :D
