10.55 kwh [2.93 Os]
I thought I was not going to see double figures again this year, especially as the BBC, at 07:00 this morning, was blathering on about cloud and showers blowing in off the N.Sea.0 -

:rotfl:They got mixed up, we had the cloud but no showers; are we near the North Sea; No.
Hence 1.16 O's......Last FIT payment ended 5.44 O's ish less than the previouse years for the similar 1/4...:(

It's not happening, is it....

Yesterday 1.55 O's. Not too bad....
Friday it was 1.03 O's....0 -

And you are complaining
I'm normally O's & O's ahead...only did 0.48 O's today, looks bigger in money for the day £0.5814p. :beer: 2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

HiAs I stated in my last post.....read it????:rotfl: I have had my loft re-insulated (250mm) in Jan 2012 and changed several of my old UPVC windows for newer and far more efficient ones. In April 2012 I also changed my old hot water cylinder for a larger, better insulated one. Using energysavingexp's switch set-up, I can nearly turn off my gas boiler from April to September.
Other savings have come from getting rid of my old "F" rated freezer in the garage that had next to nothing in. I also run a de-humidifier but, rather than leave it on the whole day I now use it when my solar output is at it's highest or during daylight hours. Because I am in on any days I choose, I react to the weather and run it, (and anything else) at max when SP output is good. All of my old lights were changed for LED ones too. Before SPV I left almost everything turned on and did not know what the running costs were for each individual appliance...I do now.
Regarding energy suppliers, I have been with Eon for many years (until today when I switch to first:utility) and, since 2011 (when I was paying £120.00 a month) I have had 3 different plans which have become progressively more expensive!
You may say some of the things I have done should not be included but, if I had not installed SPV and compared notes and advice on this site, I may have merrily carried on paying my £120.00 a month (or more):think:
Only 0.65 O's yesterday:( (95kWh for Nov
Thanks for clarification ....
The reason that the payback calculation is so important is due to the sly tactics which some selling pv attempt to use. We've all seen examples of potential customers being told that they can expect overinflated savings against their electricity bill, some being in the £500+/year range, therefore we should be careful not to re-enforce their claims by including savings which are not directly pv related in any payback calculations on this, or any other, thread. The earlier post ....
.... would suggest to anyone reading it that there has been a return on the pv 'investment' of 37.8% over 2 years, whilst this is not quite the case. In reality, there is a payback which is due to pv and other paybacks which are due to other energy saving measures which, of course, have also had a capital outlay. Therefore, if the intent is to lump together all of the savings, you should apply these to the total expenditure ... so (£saving/£totalcost(pv+loftinsulation+windows+HWcylinder+appliances+etc)) would be a more realistic calculation.....
Total FITs payments for 2nd year = £1735.24 + savings over Eon (Pre Solar Panels) electric and gas use of £676.00 means I'm £2411.24 better off than I would have been.
Add the £2411.24 to last years £2133.15 = £4544.39 means I have (roughly) 37.8% of my original investment back in the first 2 years ....
For example, we changed MrsZ's car for a more efficient one this year, but applying the running cost savings to the pv repayment calculation without adding the cost of the car to that of the pv wouldn't really make sense to me, furthermore it would really confuse the ears off someone else if they hadn't got a clue how the return was calculated ....
We don't really want some pv salesman referencing posts on here to support a claim of energy savings of almost £700/year as being possible if you have a 4kWp system on the East coast ... do we ????

Hi

Hi
Would agree with you on that. But TBH with or without FITs payments I would have had most of them done. Re-the loft insulation I took advantage of Eon's £49.00 offer to lag my roof....would have cost more to buy dust proof overalls than the money I paid. My old copper hot water cylinder was over 30 years old, virtually unlagged (well it had a thin insulated blanket I put on) smaller than the new one, showing signs of minor leakage and, when I cut it open (as you do) found to be at least 25% full of sediment. So really, it was a "no brainer" not to renew it. The new cylinder is Stainless steel as opposed to copper and unbelievably, it was cheaper to buy. As I stated in my last post I've renewed most of my old UPVC windows using the cash that came back to me from the FITs payments.
If I can find anything else to improve/lower my energy usage I will do so.For example, we changed MrsZ's car for a more efficient one this year, but applying the running cost savings to the pv repayment calculation without adding the cost of the car to that of the pv wouldn't really make sense to me, furthermore it would really confuse the ears off someone else if they hadn't got a clue how the return was calculated ....
I am looking at more efficient (electric) cars but feel the price + expected battery life needs to come down and up in that order:D
This looks interesting for electric car owners with SPV
