    11.9 Kwh at (true) Noon (1.e. 13:06 BST).

    First generation at 06:00BST then curve shot up beautifully to achieve 2KW at 9am. Thereafter intermittent cloud caused a jagged line rather than smooth curve. Happened to glance at instantaneous reading of 4.02 Kw around 11am - but the 5min recorded average at that time was only 3.4Kw. Less than 1.0Kw at 12:00 but picking up again now (spot reading of 3.9 but 5m average 3.5).

    Extrapolating to the smooth curve I'd like to see would increase half-day yield to around 17 (so full day might have been 34). Anything could happen between now & 8pm - probably will !

    How do we know it's genuine? Living just off the Bristol Channel (with a nice view of Weston Super Mare - especially when the pier was on fire!) I can spot fake imported tat easily. If it's not properly coated in slimy grey mud, heavy fuel oil and some additional unmentionables, it'll not pass mustard here.

    For the sake of fairness, there are some fantastic beaches further up the coast from Gavin & Stacey land onwards. But I digress, the lucky Welsh seaweed has worked its magic again, just popped over the 20 mark, which is helping to repair some of the damage on my May spreadsheet.

    Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.

    Today has certainly been better than yesterday but still not perfect (could it ever be I hear you ask). 21.75Kwh so far - but could yet be another hour or so of generation left and I'm still doing 300w so 22Kwh isn't completely impossible.

    Again, instead of a 'normal distribution curve' I've got something vaguely similar but with deep 'valleys'. Worst of these was at 12:30ish but another around 15:30 was almost as bad. Trying to visualise a rectangle that I can superimpose onto the actual curve to approximate to a more ideal one suggests that I 'lost' 4Kwh in the 12:30 dip and another 2Kwh around 15:30 but lots of other little bits that I can't quite so easily quantify. A cloudless sky all day might therefore have delivered over 30Kwh.

    Lest this seem like just plain whingeing, I am fairly satisfied with the over £10 earnt today.

    Final total 22.1Kwh

    How about finding out what you all export as this was one of the justifications for FITS :)
    Also how much has your import drop by ?

    This seaweed is from the proper Welsh; 'Anglesey'. You would, I am sure, be very disappointed if you did not secure any offer you would care to make:D.

    Early days for me. According to e-ons energy tracker, my usage has stayed the same for Leci. So I think I am being short changed with only 50% of export; not that it is worth the effort anyway at around 1.5p per kWh ish. :( But, at the end of the day, I have spent my hard earned cash, paid tax on it, to save 'The Planet'. Perhaps I may get an OBE! :cool:
