    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.

    My SSW has done me proud today with my first HAWAII of the year(and still going)
    Even my WNW is now starting to hit a couple of O's a day(at last)
    Should finish today with around 24kWh.......time to start looking at them there Tesla 2 batteries as most of that will have gone to the grid.

    I had a fault with my system; it kept tripping out the RCD of the 13 amp side of the fuse board (cos the Inverter was wired on that side) I had it removed from the RCD side and wired into the main fuse board; that cured it from tripping out the Fridge, Freezers and other 13 amp sockets in the house. When it rains or in damp condition the Inverter 'Riso' reading is often less than 20.0MΩ, and the 'Ileak' is greater than 0mA. The next day the readings are as normal i.e. Riso 20.0MΩ; Ileak 0mA. So, my advice would be to ignore it, until, it does not correct itself; then you have a problem. I am not an electrician, just quoting from personal experience.
    Not a bad day today, 3.16 O's.....
    Edit: If the item is still within warranty; you could speak with the installer and see what they have to say.

    Thanks for your reply, Oscar. I shall follow your advice, which fits my inclination. As for being under guarantee....The system is over five years old, and the firm that installed it no longer deals in solar. I had a more persistent fault three years ago, and they honoured their commitment by putting up scaffolding and sending a chap from another firm to diagnose and correct (it took him five minutes, plus climbing time). The original firm then asked ME to certify that the fault had been dealt with. I said that was THEIR responsibility, and we argued for a year (while they left the scaffolding in place!) So I don't particularly want to invoke any guarantee that might be remaining!

    Nice to see that others have had their silver spoons out for Hawaiis. Today was horrible, but yesterday was good (3.5 Os), and would have been better if there hadn't been a good old fog in the Channel which rolled up our hill until 11ish.

    As for Merlin, I think he colour-codes his scores - black for kW/h and red for Os.
