    I will double check my logs but I believe thats correct.

    We were putting out over 35kwh per day throughout summer.

    Ahh, cloudless days — unlike Sydney over the past couple of months.

    Mine's been in for a year longer than yours and we are only just over 5400kWh.

    To put it in perspective, most who don't, can't afford it, yet another ironic government subsidy that only those who a financially able it helps financially

    Financially I think it's well worth it, spend a bit more for quality components though!

    The green side of it, well, that's upto you

    I only put it on after feedback from people who's systems I'd installed, now I'm very happy I spent the money, albeit, I'm in a reasonable financial position...... And I'm a tightass

    I have not installed it on one close friends place yet, 2 reasons, most can't afford the initial outlay or 2 they won't stay living in the same place for 5 years plus

    We have 4kw in Brisbane facing 3 degrees off North tilted 28 degrees.

    Power Bill was about $420 / quarter, now have a rebate of 230-270 / Quarter. I wouldn’t do it if feed in tariff was 20ish c like talked about here – we are on 52c. I have several items on Tariff 33 (runs 9pm-530pm) like Pool, ducted AC, Deep freeze, Dishwasher – so these appliances are not calculated in the “Net Feed-in” equation.

    My system:- Motech 4600 inverter, 3 MPPT's.

    16 Panels, REC brand, 235 Watts each. = 3.760 kW maximum design output.
    These have been set up into 2 strings of 8 panels. Frames are flat onthe corrugated steel roof, which is 18 degrees pitch and faces exactly NE. - 045 degrees true.

    Installed middle of last August, reduced my bank balance by $13,750. OUCH!


    The old Faraday wheel meter was still there, was'nt changed for some time... and yes, I used to stand there, mesmerised by the wheel and number-dial going sdrawkcab.

    When the Solar went in, our meter reading was 91163, and a month later with the new, bi-directional one was installed, it was 91184.
    21 units used /purchased from the grid in 4 weeks. Less than ONE day's use previously.....

    As of today, the setup has produced 4941.6 kW/h in 3210 hours of production. From mid-August last year to end April this year.

    This averages out at 1.539 units produced per hour of operation.

    Our meter is 2917 units imported (bought) and 2854 Exported (sold at 40c + 7c per unit) Normally, the figures are on a par, often the export higher, but using our 'economical' evap cooling system or SWMBO developing a fetish for ironing... makes mince-meat of any gains....

    Our first power bill after installation of meter, was $226 CREDIT, down from n$600 or so from previous bills.... That included the co$t of the meter...

    Naturally, such good news can't last, and our last bill was only $172,Cr making a grand total now of $559 CREDIT

    Comments:-

    The roof direction is a pain, as output nosedives in the early pm, wasting all that light..... But to compensate a bit, it fires up just before the sun surfaces.

    Need a 3 rd string to face NW to take up load in the pm, especially in Winter
    Example of what I mean...

    Jan 16th. 2012

    0600 would have been around 160 to 180 W, based on other week days.

    0800 = 2127 Watts.
    1100 = 3692 W
    1300 = 3187 W
    1500 should have been around 2300 W, but not recorded... my bad.
    1600 = 1616 W
    1700 = 661 W
    1730 = 348 W
    1800 = 132 W

    Total recorded production was 28.2 units. This was a Good Day. Overcast/rainy days... well, watch this space....

    Basically, after 3 pm (1500) it stars slacking off...

    Hopefully, that helps a bit.
