    Yesterday was tremendous - 23.2Kw - had mine installed two weeks ago - best day yet and on a 4Kw system that is more than I could have hoped for at this time of year. Albeit of course peak power will occur this time of year whilst the panels are not overheating.

    Had a dire few days and yesterday took me to just over 10kWh - almost 3 times as much as the previous 3 days!
    I was pleasantly surprised to see my system had a peak of 3.1kWh at one point during the day - I only expected it to hit around 2.7/2.8 max due to my orientations.

    Very nice! I was delighted with my "over 20kWh", but I'm nowhere near that level yet :(

    Sounds a good day - though you haven't updated PV Output yet :)

    Yeah, it's beaten all my expectations so far.

    Up to 134kw total now - iboost means no gas cost for hot water as well.

    Peak output has been 3.640kw which presumably won't get any better.

    Your wish is my command!
    Though the past few days weren't as bad as I thought! I was getting mixed up with last week :D

    I clearly have similar output to you - 150kWh in the 14 days inclusive of yesterday :)


    Here is a graph of my two best days...
    http://pvoutput.org/comparelive.jsp?sid=28021&df=20140329&dt=20140408
    BST came in, in between these days so they're slightly offset from each other, but it's interesting how one was a nice steady day and one was a lot more variable in its output but still produced the same amount, basically (SolarEdge actually thinks the variable day produced more, though PVOutputs calculation based on SolarEdge's 15 minute figures disagrees)...

    Hiya, going back some, for a 4kWp system the holy grail was a 30kWh day. Very tough, needs a long sunny day, probably late June, but of course with the heat comes a decline in wattage. My best days by far were last July, when everything went nuts, I got 775kWh against a target of 592kWh, so some 4kWp'ers may have hit the magic '30'.

    3.64kW is a good sustained figure for 4kWp, as it's around 90%, but is your inverter capped at 3.68kW? If so, then you're probably right and you won't see better, but I'm sure you won't be crying about it.

    Mart.
    Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.
