    Renewables: "talking 'bout my generation" 15th Mar 12 at 11:06 PM
    Please forgive the corny thread title inspired by The Who, but this post on the bloated 'how do I make the most of it' thread prompted me to initiate a new one...
    Hi Everyone,
    I haven't been here for a while, and am interested to see discussion of how much is being generated, rather than what to do with it.

    Well, there was yet another misty and bleak start in North Notts today (Thursday), but my SSW 3.92 kWp system was generating around 3kW for just a few minutes between 12.15 and 13.00, but enough to get the immersion heater hot enough for a shower. It seems to drop below that figure before it reaches 13.55 (optimum orientation). Final figure was just over 14kWh.

    BTW, there was an item about solar generation in Germany on the radio today; you can stream it here:
    http://www.bbc.co.uk/iplayer/episode/b01d2rvn/PM_15_03_2012/
    Just click on the speaker symbol on the left, then drag the time cursor at the bottom to 25mins 30 secs then release.

    Very up and down day like a very steep Rollercoaster.

    3.38 O's

    Mrs Brush was taken out today with a well timed shot to the head which produced an instant kill. I followed up with a few more to make sure life was extinguished.

    Back up the ladder to remove all traces of the Drey. Will be checking once a month to make sure no new squatters move in under the panels.

    Hmm, this thread seems to have drifted off-topic just a tad! I got 3.95 Os today if anybody cares.

    Off to a good start this morning (once the sun had cleared the trees) generating 2.04 kw at 7am and 4kwh in the bag by 8.04am.

    5 Years old today.

    20.367 MWh of production. An average of 4073 Mwh per year.

    MCS Certificate gives an EAC of 3309 kWh per year.

    4.4 O's today.

    Just under an O behind estimate as of today.

    Knew something not right I transposed the 3 and 7.

    Hello, I have been following this thread for a while as I am interested in all things Solar. Could someone please explain what an 'O' is? I understand what the PVGIS estimate is but can't work out how that relates to an 'O' ???

    Simply put, an 'O' is the number of kWh generated divided by your array size (kWp).

    Yesterday I generated 25 kWh from a 4kWp array = 6.25 O's
