    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.

    Sixth full year figures from Bedfordshire.

    2.5kWp Hyundai panels, SMA 2500HF, SE, no shading.



    Yr 6 - Actual 2319kWh
    Yr 5 - Actual 2384kWh
    Yr 4 - Actual 2475kWh
    Yr 3 - Actual 2461kWh
    Yr 2 - Actual 2312kWh
    Yr 1 - Actual 2395kWh

    MCS 2146kWh
    PVGIS 2233kWh


    Seemed quite a dismal late summer - but still a tiny bit better than Yr 2!

    1.22 O's today and well over Nov target now, projecting 113% but sunny forecast should lift that a bit higher. Already beaten my best Nov (2016). If only I could have had this percentage in June.

    Ended the month with 141.5kWh and 115% of PVGIS. Previous years vary from 112 to 131, and then there was the Nov 2015 grey month of 73kWh.

    Leccy import was 189kWh (bit higher due to heat pump), and total household consumption was 269kWh.

    Predicting 99% for the year, my worst since 2012.
