    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.

    6.2 O`s over the weekend for me.

    P.S. Regarding my faulty immersion diverter (SOLiC200), I contacted the installer and they agreed they would replace it, no questions.....well I did send them a video proving the fault. The version I had is now obsolete so they replaced it with the latest model....and renewed my 10 year warranty.

    At Spring Equinox, you'd really expect to get best day since Autumn Equinox
    so best day for 6 months is only to be expected.

    I rather think 481 groats would have been several years wages for an agricultural labourer so probably equivalent to at least £30,000. That's a really impressive ROI for a FIT system

    Up here, I managed 17.49kWh today or roughly £8.90. Looking forward to many more such days (or even better ones) in next 6 months.

    Great day yesterday, but March is still sliding backwards, and predicting 87% now. Hopefully the weather will improve a bit now(ish).

    Poor start to 2017, but if I've got to have 3 bad months, I'd rather they were at this end of the PV season.

    Originally posted by Oscargrouch
    We're confusing two different concepts here. A pound used to be divided into 240 pennies, it's now divided into 100 new pence hence each p is equivalent to 2.4d so yes, 0.5p really does have to shown as equal to 1.2p

    However, it's not really true to say that today's pound is worth the same as a 1971 pound - although if you can find a 1971 pound note and take it along to the Bank of England to have its promise honoured you would only get a modern pound coin for it.

    Perhaps a 'fairer demonstration might be to consider that my last pint of beer with decimal money cost me 1s.6d whereas my last one this week was £3 (and no doubt if I returned to East Sussex I'd be paying nearer £4). That makes a 1971 penny's equivalent worth to be something in the order of 40p or 50p correction 20p
