Solar payments not as promised:(

Is this the nuclear electricity too cheap to meter?

Air sourced may only be sensible if you want domestic air conditioning to get a cooler house in summer. However this could mean that an average household will will be using more electricity than currently being consumed. The system becomes much less efficient during the winter months and running costs barely break even compared to gas or oil. Maybe they will short term with the 7 year early adopter subsidy which is not guaranteed if demand exceeds the money allocated. This assumes that you have well insulated house and possibly replace an existing CH system.

Ground sourced can be viable but this costs more and care has to be taken with the design of the installation, as some local councils have found when implemented on some of their estates.

What the greenwash companies are pushing (mis-selling) is retro fitting air sourced heat pumps to existing CH systems that are unlikely to to have the savings claimed over other sources of heating, more so after the subsidies end.

When the Greens come to power in the next general election we will end up with more wind turbines and solar panel farms which will need to supply a lot more electricity to power all of our CH and electric cars as conventional fuels will be banned after 2025 in our zero carbon society. No domestic gas or oil and with more expensive electricity and then air sourced heat pumps fitted to your home will become cost effective.

Don't you mean that it steals up to £2000/year from the rest of us from subsidies paid for in our energy bills?

he does. It will generate about 3.5MWh per year Market value at 4p a unit wholesale around £140.

This is a stupid question.

And more likely to vote for Leave than Remain and that promise of the Magic Beans. ;-(

No it means you were too stupid to take the government offer up when it was available. I 'spect you're an idle, dopey socialist.

why such a difference ? If £14K gives you £2k per year = £7k = £1k per year then why does £6k = £500 per year

has the sun become less bright over the last few years or is it global warming ?

So if the arrays are differnt what is this difference ?

Generation tariffs have reduced significantly over the past ten years. We spent £20K on ours about 10 years ago and get a bit over £1K pa but we are paid 54.17p per unit generated and an extra 3.82p for allegedly exporting all of them. I must say that I didn't notice a reduction in our electricity bills when we had them installed but most of the power is generated in the afternoon when we don't use much.

We spent £20K on ours about 10 years ago and get a bit over £1K pa but we are paid 54.17p per unit generated and an extra 3.82p for allegedly exporting 50% of them.

all those abandoned deep coal mines were so hot the miners worked in shorts and tee shirts, so I'm surprised they haven't been re-used as a ground-source district heating system.

It was a socialist government who dished out the bribes.

And when the Grid tripped out a few weeks back, no-one was able to use it because they all shut down instantly when the voltage dropped below NNN v

A BIG question is what happens when the panels are 25+ years old ?. Wventually they will head for landfill, but because of the cadmium and other nasties they contain, they might by that time be classofied as dangerous waste, like asbestos.

You might possibly discover that removal by a licensed waste contractor wipes out most if not all the 'profit' you have made.

Cue the PPI firms -

"did you spend £18K on solar panels but not told of the expensive disposal costs ?. Phone 0800-line-our-pockets to get Compo"

Earlier installed panels attracted greater FIT payments?

The price paid/Kwh reduced as time went on.

I have near perfect orientation. Someone who hasn't might get a lot less.

Perfect orientation is pointing South, 36deg inclination plus no shading. (To maximise power generated/year.)

Anything different reduces annual output.

Not necessarily.

You didn't read that did you? <quote>

Professor Michael Walls, of Loughborough University said: ?There are half a million installations in the UK facing south. To maximise the amount of power produced by those panels, facing south is correct.

?What we are saying that if you have the solar panels facing east-west then you can even out the power during the day. You may lose about 10 per cent of power if you go east-west but this addresses a problem that exists in Germany where because everything is facing south, you get this peak power at midday which is very difficult for the grid to cope with.

?So in Germany they are advising people to go east-west so they are smoothing out the supply of power from all these solar panels. We get similar spikes of power too, although it wouldn?t make sense for people to change their solar panels if they have already been installed. <unquote>

I'm maximising power/income.

My known mathematical limitations or Telegraph?

Average production 3700kWhr/yr at 14.38p/kWh = £785?
