    Checked panels today and found they are still covered in the Saharan dust, hopefully we'll get some rain soon that will give them a good wash as I'm sure it isn't helping the output being on there.

    Mine has similar and doesn't seem to effect output - they are pretty resilient.

    22.7 kwh for me. 5.6 o

    This morning until 12 was a perfect bell curve then plenty of clouds around.

    I checked my 25.6kwh from weds. Was pretty good but plenty of dips.

    A 30kwh day or 7.5 o can't be too far off :)

    That would be great, but you may find the difference between April/May and June/July is less than you expect. My generation seems to peak between late April and late May. Summer brings longer periods of good generation but the higher temperatures knock it back.

    Yeah, I agree - going to be interesting to watch but inverter should work fine up to 60 degrees so I'd hope late May with much longer hours of sunlight and a clear day should do the magic 30kwh.

    It's the panels rather than the inverter that are the issue - output drops as temperature rises.

    Sure. But still a good several degrees Celsius away from that point yet.

    The extra hours of sunlight will make a big difference. Judging from other outputs I've seen late May tend to be strong.

    If I divide 28.777 by 6.5, I seem to make it 4.427


    If the alleged purpose of these 'O' units is to enable comparisons, shouldn't there be some consistent approach to calculating them ?
