    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.

    At 4.30pm the mist rolled in from the sea and up the mountain, but too late to stop Rufus the roof from banging in a 16.88kw/h - which equates to 5.1 Os in new money. A Hawaii two days running! Good-oh!

    5.5 today. It's been a good few days.

    Has anyone noticed their output dropping over time? Ours still seems to be doing as well as when installed
    Remember the saying: if it looks too good to be true it almost certainly is.

    spring postponed....
    6 pm. It's cloudy and windy, with the promise of rain, but it was better earlier, and to my surprise the roof clocked up 4.1 Os. That makes an average of nearly 4.5 Os for the last five days. When the proper spring begins on the 21st, it will be interesting to see when, and whether, there are five-day periods which average 25 Os - what you might call a HIGH FIVE!
    Perhaps the 4.5 average has gone to my head.....

    March has decided to copy Jan & Feb with lacklustre performance so far. Predicting about 95%, though the weather might improve from Wednesday till the end of the month. Still, my WNW is doing ok now, and it's nice to see higher gen, and later times, plus the 1hr shift on its way.
    Just 'call me Mart'. Cardiff. 5.58 kWp PV systems (3.58 ESE & 2.0 WNW)

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.
