    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.

    Interesting, that despite variations of locality, pitch and kWp; submissions seem to be within a ballpark figure, apart from localized 'SNOW'.... Long Live the O's system... Not too bad a day here...2.68 O's....

    Yep, same(ish) here with almost identical reading to Savvy (nearby). 2.9 O's.

    Edit - Forgot to say that Mch gen is bad bad bad so far, currently estimating 90%, but some sunny days coming up which might change this, and the WNW system is actually at 98%.
