    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.

    A wonderful Maiden + half an O in the sunshine yesterday.

    Looking like my fellow Lincolnshire PV'ers had similar generation yesterday and it's looking good for today too

    More sun + more heat = less kWh today, as expected. A "mere" 6.45 Os, which is still one of my best. Currently at 70% of PVGIS for May.

    A good day spoilt by 2 big blips in the morning and afternoon when the clouds rolled in. So was well impressed with the score on the meter!

    Another great day, 5.55 O's and month end prediction now 110% if generation is average.

    Today is grey and rain all day, but after that the forecast is a week of sunshine with light clouds.

    Looking good for May.

    Half way through the month and at just over 56% of PVGIS estimate for May.


    That's just over 65 O's so far.


    Predicted to be at least 105% of PVGIS by the end of the month.

    This month has certainly started better than March and April.

    I am at about 60% and, apart from today, the next 7 days are predicted to be reasonable.

    Who knows what the month will bring but hopefully it will help undo some of the "damage" from March and April where I am "missing" about 250kWh or 46 Os.

    Given the good February there is a remote chance that I could end May back on course for the year as a whole - we'll see.
