Renewables: "talking 'bout my generation"

Also how much has your import drop by ?

Without a proper export meter, nobody can be very sure what is happening. Export is NOT a 'justification' for FITs. The two parts of the scheme are completely different. FITs are the major component and are a 'reward' for generating rather than a payment for exporting. The (deemed) export payments are a very minor component. The principle behind the FIT scheme is to encourage more 'green' generation - whether it's used or exported, it's electricity that hasn't had to be generated in (say) a coal fired station.

Hard to be sure exactly how much our imports have dropped. Just to complicate matters, I changed REC just before installing the SPs. However, our calculated monthly direct debit (based on what I expected to use in the first year ignoring SPs) has proved to be way too high & has already been dropped by £20 and when I get the summer quarter import figures I expect it to drop further.

Well, 9 months in, my targets and guesses are looking reasonable, so including a poor April and May (though fingers firmly crossed) I'm predicting 2,850 generation, with 1,000 less import and therefore 1,850 export, against assumed 1,425.

I'd guess that most people with similar or larger systems/generation will probably be exporting around 60%+.

I agree re export meter, thoguh might be possible via owl or additonal logging meter with the right feed setup on the meter tails etc.
Just wondering , whether as anidotial evidence has been suggesting , electricial usage actually goes up after PV installation ( though import may stay similar or drop slightly ) due to a less fruggle mentality of the system owners.
If this is the case then export should not be a 'minor component' though I agree the payment structure of FITs make it so currently.

I have 'the right setup' on my Wattson meter so get a permanent indication of the instantaneous situation in our kitchen. I don't however bother to download results from Wattson to computer to get daily totals etc - I have tried but didn't find the Holmes Software at all 'user-friendly'.

Looks like being another 'silly day !

2.5Kw peak at 08:55, dipping to 288w at 09:10 but we're back up to 2.6Kw now (09:40).

However, 2.5Kwh on the day already - which is more than enough to pay the interest on the installation fee that isn't in my ISA any more.

Today only 13.2

Per Day kWh Value

Nov-11 2.84 £1.28

Dec-11 2.02 £0.90

Tried to align, but would not work .

Everyone is a bit quiet on this thread today.

Just crept over 17kwh for today - might get a bit more before it shuts down but probably not more than 17.5. Not bad for the first day - peaked at around 3.4kw at around 2pm which isn't bad for a 4kwp system split 9 SE and 7 SW (35degree slope). In some ways its been a good day for generation - when the sun has been out its been clear but windy and cold, so keeping the panels cool - just too many showers taking big bites out of the generation curve!

Glad someone is happy:mad: 8.3 = £3.90p here; think I will move my panels to an area without 'global warming':rotfl:.

BOO!

(Maybe I should've gone with Shush!)

Anyways, another good day in daffodil land, got 20, and hopefully tomorrow will be even better, so 4 out of 5 days very close to my systems maximum potential.

Yes I know I'm gloating, but it beats my usual vicarious existence of staring at everyone else's numbers!

Have fun in the sun tomorrow (unless it's snowing).
