    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.

    Wet and windy here today so an appropriate two little ducks at 0.22 O. Now back to 92% for the month and tomorrow is not looking good either.

    Yesterday scored a zero, not entirely unusual at this time of year for my ESE TGM to clock a zero as it moves in whole kWh's, but a zero from the WNW TGM which shows 1/10th's is a tad on the pathetic side.

    A miserable morning returned an equally miserable 0.1 O, then the sun came out until sundown taking us to 0.66 O. Still under par for Jan but giving a useful return sufficient to power the ASHP's and top the thermal store up.

    Nearly got an O with 0.91, which isn't bad for my system at this time of year.

    The worst part of owning an E/W set up, when the sun is low, is having generation drop during mid day (edit - because none of the panels can 'see' the sun), which seems like a bit of a pee take.

    Currently predicting 92%, so could be worse.

    After an up and down day a whole O here today nudging us back up to 93% of pvgis. Possibly a bit more sun in a couple of days time.

    Yet another poor day, 0.1 O's and still only at 28% for the month.
    Although judging by the weather forecast, the next few days look like they might come to the rescue.
