Cheers, thanks. I'm not sure how you could ever test / prove such things but ...

I think I once saw some slate sized individual panels that were wired in series to make a bigger (potentially roof sized) panel. I wonder if they actually still exist out there?

87% efficient PV?! No.

87% of the orginal 15% - 20% effciency of conversion of light to electricity. So 13% - 17% hopefully after 25 years.

As for the control gear guarantee it's not worth the paper it's written on if it's not backed by some form of insurance. If the company offering the guarantee ceases trading you're stuffed without an insurance element.

They use them in National Parks and what have you. Very expensive.

I can't tell. There are four components, only two are measured so I don't know the other two. (Kirchof's Law)

I now generate about 8000Kwh/year. Guessing, probably export more than three quarters of it. You are DEEMED to have exported half for the purposes of payment. I don't believe that's possible without something truely extraordinary.

As for electric cars, the car has to be at home by day to use PV power for charging. Which I mostly am. But if you were at work? Even so the battery only holds 16Kwh. In practice you don't use it all.

No he doesn't. He's paid for generating it regardless of whether he uses himself or not.

I can't see how a commercial unit can justify the cost. Just how much hot water does a household (excluding the 2 + 20 kids families) use in a day?

But he pays upfront for the kit. That has to be amortised. The only way you can get free heat from the sun is to stand outside.

Ah, where you can't just bung some ugly panels over your existing roof you mean?

Could be a small price to pay to make the function of generating electricity from solar energy 'transparent' (physically and atheistically).

That said, there is a communal building (warden controlled) that has an artificial slate (west facing) roof where the entire roof is covered in black solar panels to the point that is *is* the roof (aesthetically). Apart from looking like it's wet (raining out) all the time it's not that bad.

Q. If it wasn't for the FIT, would you still have invested?

It's a matter of perception,the same could be said of TV aerials and dishes. I 'spect your ancestor was whining when chimneys were invented.

I probably wouldn't have hard of them. If it wasn't for FIT, panels would not be as numerous/cheap as they are. As you're clearly not clever, the purpose of subsidy is to induce the public to take some action that has been deemed desirable by some Government think tank.

Once people get used to the idea, subsidies can be reduced. Which is exactly what happened.

BTW There is a scheme which pre-dates the FIT still running but is was not so widely advertised/known about.

The whingers that appear here are brain dead, all form of electricity generation are subsidised. If someone wants to put panels on their roof or erect a wind turbine it's none of their business. To many ignorant busybodies around. Probably socialists.

The fuel is free. Don't be pedantic. It makes you look stupid.

There has been no noticable change in performance in almost four years in my panels

None of the hardware is guaranteed for 25 years and the inverters are

*expected* to have to be replaced every 10 years or so.

The only guarantee is on the size of the original FiT payments. Later installations don't get 25 years.

Yes ... guaranteed .. its a Tier 1 rated panel

Correct I get paid 50% of what I generate ... so the more I use (for free) the better.

With current interest rates ... I'm getting better payback form Solar than I would get from a bank account.

It could indeed, and boundary fences etc.

I doubt is as chimneys are a basic function for anyone who wanted heat (after a simple hole in the top).

Does FIT apply all round the world then? Do you think the UK is leading the solar takeup?

It's because I'm clever (and have morals) I can see the system for exactly what it is (and as you partly describe). It is an inducement that penalises the majority on the (non justifiable) whim of a minority.

I wonder what percentage of the people who fully understand the bigger picture have *chosen* not to take up the FIT concept on moral grounds?

ie, I've been making good use of solar (both PV and water) for *years* and might consider such for my house *if* I thought it would be a good thing all round.

Not sure that's going to happen any time soon though is it? People taking it up in greater numbers?

Yes, the government realised it's costing us too much money in this time of austerity and the populous don't like it. *You* buy your panels yourself and by all means sell any surplus power that_you_don't_use at the standard rate.

I'm sure there are ... like the 'stand on your own two feet' systems.

We know, just not as much as the FIT system, even though it's now reduced to something less like theft.

Quite, as long as that also applies to all / every other modification that would normally require planning permission. I'm sure you would be the first to cry when someone did something you didn't like.

Or people who are reasonable and so don't condone theft?

See above.

Not in my case ... my panels are guaranteed in terms of product for 25 years, and guaranteed in terms of minimum solar conversion efficiency for 25 Years. The per panel optimizers and the inverter also guaranteed for 25 years.

Some kit only gives 10 yrs ... I went with kit that has full 25 yr

All guarantees are also held by a 3rd party company, so covered in the event supplier goes bust. Things have moved on a lot in terms of product.

Hopefully that is an insurance back thing not just A.N.Other company who could go bust...

Appears so, just out of interest what was the bottom line, all inclusive, install cost for your 4 kWp system?

Cool. When do those of us without solar panels but who use electricity get our cut (being as we are sponsoring you as such)? ;-)
