    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.

    Ooops! Thought I'd posted our 0.23 O's around tea time, must have missed the post box! After yesterdays excess it brings us back inline with pvgis.

    I got 1.02 O's but sadly that's over the last three days total.

    Now predicting 99% for Jan, so the typical ups and downs of a winter month, where 0%-200% of daily PVGIS is common v's perhaps 50%-150% in the summer, and no idea how the month will conclude.
    Mart. Cardiff. 5.58 kWp PV systems (3.58 ESE & 2.0 WNW)

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.

    Good news today 0.43 O's, the good news being that our neighbour at the bottom of our garden has let me cut down the bamboo causing partial shade at this time of year. Even better news, he's going to take it all out and replace with a shed. But still about 10% under pvgis for the month.

    Wow, cutting that bamboo down hasn't half made a difference, 1.59 O's today. Mind you unbroken sunshine for some of the time helped a little.
