    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.

    Well that's more like it, less sun but more Os thanks to the lower temperature. Got 6.19 Os today and some amazing (for me) peak generation figures - 1964W recorded on the monitor off the inverter output and 2000W on the inverter display, which is not bad for my 7-year-old panels that can't be running at much more than 95% output by now.



    They never get over 1600W when temperatures are up in the high 20s or above and, considering my old inverter was limited to an output of 1575W, these figures are great and give me hope that, given the right conditions, I can exceed 7 Os (highest I got on the old inverter was 6.6). Happy days!

    Goes to show how much better production can be when the temp is lower and you have some wind. Clouds have been coming and going all day and my chart is covered in peaks and troughs!

    Another Maiden + 0.11 O's and some still to come.

    Averaged 6.24 O's over the last 6 days!

    Another pretty good day with some nice peaks and 5.78 Os. That gives me a 7 day total of 42.54 Os (average 6.08), which I'm pretty sure is my best week ever.

    1st Maiden of the year, 6.04 O's today.
    The cloudy morning and cooler temperatures today certainly helped to boost generation.

    No full Maiden for me yet, 5.77 O's. But squeezed an ESE Maiden, and my first Hawaii of the year for the WNW.
    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.

    6.4 O's today, making six maidens in the last seven days. Mind you, it's not looking good for the weekend. But all the same, what a start to May!
