    0.25 Os here. Almost a non-day.

    My hour's swim today calculated out at 784 kilo calories, more or less equal to today's solar generation of 0.88 kilo Watt hours.
    I have osteoarthritis in my hands so I speak my messages into a microphone using Dragon. Some people make "typos" but I often make "speakos".

    Just short of 0.22 O's here today. Have to wait till its dark to know when production will finish as I cannot see the sun!smiley-laughing021.gif

    Total production came in at 0.2997481smiley-computer001.gif

    I think I can just about call that 0.3 O's then!smiley-laughing021.gif

    I had a similar problem at first (-: It seemed such a rationale approach to comparison that I was Googling for the answer. Apparently, it was invented here. It makes sense provided that denominator is the DC output of the system rather than the rated AC output of the panels.


    Sorry, wrong way round (I realised) "It makes sense provided that denominator is the AC output of the system rather than the rated DC output of the panels.

    Ended with 0.24 O's today; it's now snowing, so the morrow could be worse....t1940.gif......smiley-laughing021.gif....coffee.gif
    2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.
    Reg. for FIT Nov 2011. "It's not what you generate; it's how you use it that matters". One very clean Vauxhall Diesel Sri, £30.00 Road Tax: B)

    Definition of 'O's = kWh/kWp (kWh = your daily & accurate Generation figure) (kWp = the rated output of your PV Panels).

    Oh! I need this clarifying now as I'm confused.

    I've used the rating of the panels in my "O" calculations (3920w), not the rated output of the inverter (3600w).

    Which should I be using Oscargrouch?

    Panels, no question. Maybe Oscar could clarify in his signature.
    2kWp Solar PV - 10*200W Kioto, SMA Sunny Boy 2000HF, SSE facing, some shading in winter, 37° pitch, installed Jun-2011, inverter replaced Sep-2017 AND Feb-2022.

    The panels output DC, not AC, which the inverter converts to AC. In any case, the Os calculation uses the rated output of the panels, not the inverter. If I used the inverter rating some of my peak O ratings would be implausibly stratospheric.:)
