    Renewables: "talking 'bout my generation" 16th Mar 12 at 12:06 AM
    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.

    Last day of the month and woke up to 3 inches of SNOW!

    Not expecting much so well happy with 0.8 O's

    197.7 kWh's and 146.4% of PVGIS.

    Nov 2014 121.2 kWh's

    Nov 2015 115.9 kWh's

    Nov 2016 173.4 kWh's

    At 107.8% of Year PVGIS but looking to be my worst year.

    Hi all,

    Hope I'm welcome to this group I just had solar installed so look forward to contributing!

    Today(assuming I won't generate anything worthwhile now that sun has basically set) = 0.94O's.

    I realise this is a 'made up' value - but what would 1 "O" mean? In English? Or is it just a relative scale we can all cross compare?

    Hiya. The O stands for 'Oscars' as it was he of the grouch family that wanted a comparison figure. The real name is simply kWhs/kWp, but that takes a lot of typing .... hence the O's.

    It gets sillier as O's lend themselves to nicknames, such as a 'Hawaii' for 5O's, or a bond for double O's.
