  • Second reading submitted to our FIT supplier yesterday. Another £592 to come to us in the next 28 days! Installation was on 21/2/12 so up to the end of August we'll have been paid £1,107 in cash and used 1170kWh's less than last year, which is around £140 saving.

    Still can't quite believe we got the higher rate of FIT but more than happy that we did!

    If only I could have spent the pension pot on 10 installations!
    4kW PV System installed 21/2/12: Aurora Power One 3.6 Inverter
    11x 250w panels West; 5x 250 panels East.
    On course for 19.8% ROI in Year 1.
    Immersun installed 13/9/12

    Could you please book two tickets; I will come with you.....cheque is in the post ! :rotfl: 1st - 15th of August I managed 147.1 kWh 16th - 31st managed 150.9 KwH. So, 394kWh for August equates to 98.5 per Kw system, my 289kWh equates to 115 per kW system....is that right ? :question:

    Looks right to me. About 116kWh/kWp is about the most I can expect from my ESE in June (actually got 96), my best month was May with about 124 (when it should have been 110). Really wacky year this one.

    Just reading up on SAP, really need to get a life!

    It calculates generation by multiplying kWp by 0.8, then for true South, multiplying again by 1073, which gives approx 850kWh/kWp, which coincides with Sheffield on PVGIS climate.

    Even Inverness still clocks up 798kWh/kWp but areas in the south can easily hit 1,000, even 1,100 for a few lucky people. So it's really not very accurate, and quite a strange compromise.

    Found one site that says that for SAP 2012 21 regional SAP tables are being considered / discussed. Surely it would be easier to agree on a site such as PVGIS, then allow installers to give personalised quotes to householders. This might encourage those in the south put off by 'old SAP' and deter those in the far north that might otherwise be mislead.

    Maybe I should just think less and go and watch some Family Guy, or American Dad instead. Probably more educational, or is that Southpark!

    Change of plans, if we're going for this let's do it right. Tickets booked for Cornwall, tablet loaded with the most extreme episodes of SouthPark, couple of bottles of cheap moonshine collected, and a trailer load of Lidl extension leads purchased.

    We'll take 'SouthPark' length shifts, one drinking, the other hanging out the train window linking extension lead after extension lead - what can possibly go wrong! :eek:

    I think I'm beginning to notice a pattern of nonsense that seems to set in around 9pm. You'd never believe I used to be one of those business suit professional types in another life!
