    Got 15 + 8 yesterday, and 18 + 9 the day before. I think that's pretty good for time of year, location, size orientation etc. So Cardiff must have got a little better weather than average.

    Also got second ENViR monitor set up yesterday, side by side with existing one. I was tipped off that the solid red on the new Elster TGM might not crash my Optismart, so I tried it for a few days and it was fine. Then total luck, logged onto 'that auction site' searched for 'Eon energy monitors' since they are mostly ENViR's given away free. Found one without a clamp and transmitter for sale. Got it for £6 inc p+p. New Opti was £28.

    Having both monitors side by side was a surprise, we got 3kW from 10am right through to 3pm. Starting off 2.5kW E + 0.5kW W, slowly switching to 1.8 + 1.2. Then 2kW (0.5 + 1.5) till 5pm, and at 6.30 0.2kW + 1.1kW, which meant Olympics on the telly plus microwave cooking, and still a solid red on the import meter.

    A week ago, during a very nice spell at mid day, the systems actually held 4kW (perhaps 4.2kW) from about 12 till 2pm.

    I said a long time ago, that 5kWp spread over an east/west install, might actually be as useful as a 4kWp South install, if prices keep falling. Plus many houses have room for 2 to 2.5kWp, not so many for a full 4kWp. I'm still thinking the same.

    Mart.
    Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 28kWh 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.

    Just get the key off, and wash it with hot water and try and clean off the bit that it sits on first....:money:

    But that's basically it for now - very little sun forecast for the next 5 days. :(
    So much for the forecast - mostly sunny day and 9.57kWh. But tomorrow ... not looking good, hope they're wrong again!

    Dismal forecast for here too today. Thankfully, they were wrong again - quite a few sunny spells giving daily total of 12.93 kWh (fractionally below a pvgis typical August day).

    Quarterly FIT reading taken at sundown yesterday.
    Surprisingly, up almost 19% on same quarter last year :j (sure hasn't felt that way! :D) and up just over 1% on comparable six month period, mid Feb - mid Aug.
    Considering what a spectacular spring we had last year, I'm really surprised - pleased, but surprised :)

    Overall, since installation, we're still over 20% above predicted figures - in fact, according to one of my spreadsheets, even if we don't generate another single kWh between now and the start of 2013, we'll still be 'on' prediction'! :rotfl:
    Everything will be alright in the end so, if it’s not yet alright, it means it’s not yet the end
