    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.

    I think the heat and the dirt are taking a toll of production! Need some rain(over night of course) to clean my panels.

    Thought about getting up on the roof from the front and tipping buckets of water down over the panels but the B&C would not let me use the butt water. She needed it for her raspberries! Why not use tap water for the raspberries? Butt water is better she says!

    All's well here for July, a lovely 5.89 O's yesterday, and predicting 105% for the month. Each great day pushes that up about 1%, and the long term forecast is mostly great days to mid July now. One day (week today) it might even rain.

    Too hot.

    Picked up my new car on Friday and we have been away for a couple of days to see the Grandson in Suffolk. Warmer down south!

    Friday 4.97 O's

    Saturday 6.51 O's

    Sunday 5.02 O's Could make a/an Hawaii if I get another 25 Watts.

    Up and down a very long ladder this evening with buckets of Butt water to clean the panels. I managed this after I pointed out that the water I used would end up back in the Butt!
