    Pleased with 6.5 O's yesterday after a slow start. The one thing I noticed was that although it appeared hazy at times it was seemingly cloudless at others but my system didn't seem to go over 3.2kW. It normally maxes out around 3.7 on clear days. Do I have a problem or might it be haze / temperature related?

    If I remember rightly on working it out, 7.9 Os today.
    Though my 3.99kw WSW only peaked at 3.5kW I suppose the heat degrades the efficiency.

    I've had a similar experience. My 3.3kW system only got to 2.4 kW today so I reckon this looks pretty normal for the heat.

    Managed a best ever of 6.4 O's though. And finally above estimate (I know it's early in the month) by 7kWh

    What does your normally max out at? My 4kW system usually stops at 3.7 but did not get near that yesterday.

    I've seen peaks of 3.7 kW in cold mid-day sunny weather in May. My split system should in theory give a flatter curve: lower peaks and longer evenings but I've found my best panels massively outperforming spec on occasions (over 350w)

    A better comparison would be that at 12.00 today I was getting 1.7 kW. Last month similar sunny conditions were giving be around 2.4 - 2.8 kW.

    5.8 O's yesterday. Still over 7 O's short for the month (was ahead by nearly 4 O's at the same point in May).

    I had peaks of 3.1Kw yesterday, compared to the max I have seen of 3.2Kw
    Discussion has been around haze, but could it also have been due to dirty panels? I noticed something on the panels yesterday, it was getting dark and it looked like something from the trees?

    Fair point. In the last week we've had rain containing a lot of dust which has left a coating on both my car and the panels.
