    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.

    2 rotten days down, and 1 more to go, before a promised (yeah right!) week of good sun.

    Still above target but sliding down.

    More lovely rain overnight and more promised - but yesterday was a sub-maiden (5.8 Os). Unfortunately something (and not the thermostat) has caused the 6 month old immersion to give up, so no free hot water.

    It's been raining practically all day but I've still managed 4.076 kWh which is at least twice what I need to generate to compensate for the interest lost on the cash used to buy the kit.

    But on the bright side, I've collected almost 3 cu. m of rainwater over the last couple of days so should be able to flush lavatories for the next six weeks or so

    We never actually ran out of rainwater - we have storage for 4 cu m. And indeed a backup plan for flushing with drinking water if we use up all the rainwater stock.

    When first commissioned, I only had 2 cu m of storage and was having to flush with mains water for a week or two most years. Since increasing to 4 cu m we've never run out.

    Well, those 3 days were fun. They eviscerated all excess that had built up. Now predicting 596.6kWh v's 597kWh target.

    Still, a good weeks forecast ahead, so hope yet for my first plus month of the year.
