    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.

    Forecast was for a nice day, but got a super day. Also generation on the ESE sat at about 90% till the sun moved away (very rare during sustained sunshine), so there must have been a nice cold windy boost.

    At 5.75 O's, very near my best ever.

    Today is to be even sunnier, by 90% of Wp rating will take some beating.

    6.04 O's for me yesterday which is the 6th day so far that I've passed 6 O's this month. I've exceeded PVGIS every day so far this month and currently stand at 65% of PVGIS for the month, which is a real turn round on the year so far but still worse than last year.

    Looking back over the month so far, a very encouraging 72 O's though.

    All-time record smashed!
    Right, 8pm, generation shut down and I have smashed my all-time record set four years ago! 6.75 Os today, but still that elusive 7 evades me. Perhaps I could have got there today but for a few clouds in the early afternoon. Tomorrow's forecast looks good but probably too warm to break any records. But, the end of the week looks more hopeful, sunny and cooler.
