    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.

    Had a pretty good August. Generated 514 kWh (compared to PVGIS forecast of 403 : i.e. 27% above forecast).

    According to Immersun monthly figs for August were :-
    Desc Immersun
    Imp 440.90
    Exp 23.60
    Gen 508.90
    House 684.20
    Diverted 242.00

    However, the Immersun figs aren't as accurate as I might have hoped.

    Actual generation (from TGM) was 514 and actual imports were 367 (split as 136 day, 231 night). 129kWh of the night units were for charging EV.



    N Derbyshire.
