So enough for four days of just the house electrics really - not even any heating, doesn't run the car, or transport your food to the supermarket, or grow it.. and is worth all of £5 on the unmanipulated electricity market. Golly that's a real ROI innit?
I seem to recall it peaking on a sunny day late in December at about
600W output. Have regularly seen 2.1kW peak output in recent weeks.
The average TOTAL energy consumption PER PERSON in the UK (not per house) overall is about 5KW.
My investment in the panels was precisely =A30.00. So not bad in those ter= ms...
I assume you've missed a "h" in there. Is that 5kWh per day? Before solar= , my household consumed about 4,500kWh per year, so across the 6 of us that= live there that's just over 2kWh per day.
But you're right, it makes only a small difference. My house net now draws= about 50% less from the grid (net) than it once did (less than that if you= measure the solar which we actually manage to intercept and use - probably= less than 50% of that 50%), I reckon we'll generate about 2,250kWh per ann= um, and use somewhere less than 1,000kWh of that generation.
We've got one of the "rent-a-roof" installations which didn't cost us anyth= ing (well, apart from the subsidy which I am paying to the installer throug= h my general electricity bill, as the rest of us are too).
No, it's 5kW. That's 120kWh per day. You omitted to include all the kWh expended elsewhere in the country to support the average's person's lifestyle. Elsewhere than in your house, I mean.
OK, I'm no expert in these matters, but I didn't think that 5kW was actuall= y a measure of quantity, rather a measure of power output at a moment in ti= me.
Happy to be educated about why I'm wrong, but instinctively I'm not convinc= ed I am!
I agree of course that usage of electricity is higher than just that consum= ed in the home. According to

the ele= ctricity use per person in 2009 was 6,005kWh, which is about 16kWh per day.
Being the sum of all the energy it takes to make/grow/process the stuff you buy and consume or throw away..and get it to you (or you to it) and the make-believe job the government will surely give you if you whine loudly enough, to justify you having it in the first place...
Judging by the over Christmas/new year electricity stats at least 10% of the nations electricity goes on 'work', most of which is probably irrelevant - why we don't just pay public sector workers to stay at home where they cant f*ck things up I don't know.
measure of quantity, rather a measure of power output at a moment in time.
it isnt. Its the average used per capita. the rate of consumption of energy.
As I said.
There's is no point in talking about 5 kilowatt hours per hour, or some other stupid figure, when it boils down to 5 kikowatts without the hours per hour, which is always one.

The logic of renewable energy is simple.
It makes governments look like they are doing something about climate change, at no cost to them and no taxation cost except in terms of increased electricity prices. It actually does nothing but make electricity more expensive.
It doesn't affect fossil fuel burn at all really, so the oil companies are happy.
Manufacturers of wind turbines PV panels and gas power stations are happy,. That's Siemens, so it keeps the Krauts happy.
The left is happy because it creates green jobs thus being and equivalent to stuffing yet more fat arses on office chairs to f*ck things up.
Of course it totally wrecks the environment, leads to a trebling of electricity prices and dies nothing to improve energy security - but hey, who gives a shit about the planet, or people or wealth creation??
It is doubtful whether the UK's carbon emissions are better than 1% lower than they were pre windmills.
And with gales sweeping across the North sea, at least half of em appear to be switched off.
I bet harrys PV panels are not producing enough to cook a meal on, today.
But I've just give you info to establish that the average consumption per d= ay per individual in the UK is about 16kWh, so I don't know where the 120kW= h comes into it? =20
I do agree, drawing 5kW constantly gives 120kWh consumption per day. But T= NP posted that "The average TOTAL energy consumption PER PERSON in the UK o= verall is about 5KW". So he says "consumption" and then gives a power outp= ut measurement, which I am now 100% convinced I am right in questioning. A= nd then I provide reasonably well referenced source data which actually sho= ws that the "5" (with the correct units) should actually read "16", and eve= n then that is just for electricity, whereas TNP says the it is "energy", s= o presumably includes gas and oil too, so even my well referenced 16kWh is = too low (I think the total energy use figure may be about 37kWh from a wiki= pedia source).

So you're figure of 5kW on-going consumption is wrong then? Do you agree o= r disagree? 16kWh per day seems to be the "right" electricity figure as fa= r as I can see, which is 0.6kW in your terminology (0.6kWh/h if you like).
(Putting my house into your terminology would say my house (ignoring my wor= k life etc etc etc) would use 0.5kW, or somewhat less than 0.1kW per person= ).

Hating myself now - can't believe I wrote "you're" when "your" is correct. = My children would be caned for such an error ;-)
I told you before. You omitted to include all the kWh expended elsewhere in the country to support the average's person's lifestyle. You only included your energy consumption *at home*, which is just a part of your overall energy usage.
My Eon-provided wattmeter says we're using about 350W at the moment for two of us. So that's about 8.4kWh per day. 350W is a *rate* of energy consumption. 8.4kWh per day is also a *rate* of energy consumption. And TNP is therefore correct (from a terminology pov) to say that the average person's *consumption* is at the *rate* of 5kW.
No you aren't. E.g. 350W is my instantaneous consumption rate. It works out at 8.4kWh per day. But the 8.4 figure is an *average* rate, which I could get by using power at exactly 350W for a day, or by my instantaneous rate fluctuating (as of course in reality it does) in such a way that, over a day, the average consumption is 350W.
I haven't been following closely, but isn't one figure for in-home consumption per person, and the other *ALL* consumption including offices/factories/shops/factories/steet-lighting whatever?
Above, you say " ... 120kWh consumption per day". So you're agreeing that "consumption" is a rate of usage. Why then, are you complaining that TNP " ... says 'consumption' (a rate) and then gives power output measurement (a rate)"?
I'm not TNP, if that's who you're referring to, so your point is *what*, precisely? meanwhile I was teaching larkim that a rate is a rate. 350W is a *rate* of consumption, as is 120kWh per day.
We looked at having a solar installation but with a maximum of 6 panels on the roof (mansard roof on a semi) the projected payback figures were too extended to make it a worthwhile investment. At the time (about 6 months ago) you needed about 10 to give a reasonable return, and going up to about 16 made the figures a lot, lot nicer.
Either things have changed dramatically or a lot of people are finding the same sort of cost/benefit a lot more attractive than we are. I suspect many are doing it because if you don't get it now the FIT will be cut right back, not because it makes sound economic sense.
