    Renewables: "talking 'bout my generation"

    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.

    Hi, we had panels installed on the 18th Jan so still trying to figure things out. Yesterday we had 1.89 O's which is the best we've seen so far since the install so looking promising.

    I wonder if you knowledgeable people would be able to answer a stupid question from me - if at a moment in time the panels are generating say. 2kwh and the household consumption is 2.2kwh. Would the entire 2.2kwh be drawn from the grid or just the 200 watts to make up the difference? Cheers.

    Hi, we had our system installed in Mar 2016 with an estimated generation of 3650Kwh per year. To date we have only generated 5862Kwh so way below what should have been generated despite a record breaking summer. Does anyone have any advise on how to hold the company Ecoscheme to account for the shortfall.

    I will see your 3.7 and raise you 5.4O's

    Yes you read that right 5.4 O's or just shy of 23kw.


    Goes like a train this roof in cold bright weather.


    Iboost nabbed 17.49Kw of it and the dishwasher has been on.


    That's what I talkin' about!
