    Renewables: "talking 'bout my generation"

    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.

    Well, seems she took one look at me, had a fit and ran straight back again leaving an Hawaii in her wake.

    Mind you with the daylight hours reducing rapidly now I can't see there being to many more.

    So much potential or lack of today. The panels stopped generating at 7.30 am. Rang Moixa support - obviously no one working Saturday. Eventually worked out it was a RCD that had tripped (no idea why) and reset it just before the clouds rolled in.

    0.5 Os.

    Wooden spoon again then. 1.08 Os today. I think there should be a special adjustment for those of us who are directionally challenged, badly inclined or just downright shady.

    Corrected from last nights entry. I had taken the wrong start figure. Had been a bit surprised at how low it was relative to Merlin. 82% is about the norm.

    Amazing how much variety there is with our generation, a poor day here as well, but 2.4 O's.
    I just wonder where the sunniest place is in the uk? Perhaps we should all move there, or then again, perhaps not!
    Maybe over the course of twelve months it all evens out with not much variation between us!

    Early finish tonight. 2.3 Os. 45% for the month (I think, if I used the right calcs) but did lose what might have been one of my best days due to technical issues.
