    Renewables: "talking 'bout my generation" 15th Mar 12 at 11:06 PM
    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.

    Month end prediction has slipped down to 92% now, but hopefully the fight back starts today, or perhaps this afternoon (not great for an East heavy set up) as the sunshine returns.
    Mart. Cardiff. 5.58 kWp PV systems (3.58 ESE & 2.0 WNW)

    Fairly typical day of late. Good morning, poor afternoon and good evening. East roof 3.94 Os, west roof 3.93. Overall 3.94.

    Now two thirds of the way through the month and have only made 53% of the full month target or to put it another way I am on target for only 79.7% of PVGIS this month if things continue as they have to date.. That seems pretty poor to me. Is anyone else that far off PVGIS?

    Also disappointed I have not yet had one really good June day to see what the system can do (just scraped one Hawaii so far) as not only does the E/W roof benefit from the longer days but the sun being high in the sky hugely improves the performance of the E/W panels in the midddle of the day. I got a glimpse of the potential a couple of days ago when by 11.35am the PV had ramped up to 6.2 kw only for the cloud to roll in before the sun reached its zenith.

    Maybe tomorrow... but I have been saying that to myself for the last few days.

    Just over 58% of June PVGIS, so a little better than you.

    Weather improved yesterday to 4.76 O
    Today it was summer (!) and 6.5 O. Will get a little more as it's still generating 0.15 kWh, but I won't be able to read it again until Sunday.
