    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.

    Of the 24 kWh generated 13.5 kWh was diverted to the hot water cylinders by the IBoost.

    Boy oh boy it's messy, especially if you've had your driveway dug up! My suggestion to Wifey to leave doing the front of the house till June for better weather.

    Gen has dropped rapidly from a predicted 99% to 95% for June, and things look bad till the second half of next week.

    Even had to use the small heat pump to top up house temps, but at least that's using free PV.

    The hot water cylinders had a lot of catching up to do. Back to normal today with the IBoost harvesting 7.3 kWh.

    Today was an east roof day with 4.64 Os while the west made 3.14 Os. 3.82 Os overall is just over daily PVGIS target - not too disappointing considering the cloud and several showers we had.

    50% of the month now gone and only 37% of the monthly target achieved means 4.57 Os per day is now needed for the rest of the month to reach PVGIS
