    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.

    3.3 0s in NW Lincolnshire. Most of it in the morning. Found some shade on one of my panels at 8.30 so out came the chainsaw. Actually I was surprised at how little it affected the output.

    Sorry I could not post yesterday but I was dragged to the cinema by her in doors! I bet you can guess what she made me watch?

    Back to business. Reasonable morning and then it was just dire! Cloud, cloud, dark cloud, light cloud and then it rained! No the sun came out around 18:45. What use was it too me at that time of day? Never saw it as I was on the way to the cinema!

    Oh for anyone who cares the Film was Mamma Mia 2 (Not as good as the first in my opinion which goes against the critics)

    2 Os. So near yet so far. Frustratingly the western horizon has looked bright all afternoon but only after 6pm did the sun peek out fleetingly from behind the sheet of cloud.

    After a brilliant start to August then down to earth with a bump today. Reckon we might even take the wooden spoon.

    0.62 O's our lowest daily figure to date. But amazingly monthly generation 145% compared to pvgis!

    Back up again today thankfully, 3.9 O's as opposed to pvgis August daily average of 3.55!
    Even better, charged the EV with 13.6 kWh's of 100% solar energy.
