    Renewables: "talking 'bout my generation" 15th Mar 12 at 11:06 PM
    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.

    With some on here getting interesting prices as they went bigger and bigger, I'd take a complete guess at about £12k-£14k? Is the location on a 3 phase supply?

    Poor day at my location (Where my panels are)

    Ended the day with 1.2 = 0.84 O's or 3.35 kWh's

    Figures and a location are in the gaps. You just need the code to be able to see them.

    What does PVGIS forecast for the period ?

    Their figures are averages of a 30 year period. Last year was above average in most places, this year has been below average for most of us. Most years, a couple of bad months are followed by a couple of good ones. The time to worry is when you get several successive months all below PVGIS forecasts.

    Not really significant but don't forget that February this year was shorter than last year's

    I hope there are some other Hawaiis from the rest of you.
