I may be wrong but if you are using the electricity when it is being generated during daylight hours, then this electricity is free

The electricity is free once the cost of install has been recouped, approx 10 years, after that its all free

If you take true cost of recouping your 'investment'(including loss of interest or cost of borrowing) then it is highly unlikely to be 10 years. i.e. you cannot say install cost £10,000, income £1,000pa - so payback is 10 years.

After the money has been recouped, maintenance will be paid for out of that 'free' electricity.

Hi, I am a newbie so not sure if I am posting in the right place.

What is the best price any one has found for a 4KW installation in North Yorkshire

James, you're best asking for a system that is just less than 4kHw as anything over is classed as "commercial" and the FiTs (Feed in Tariff) drops from 41.3p to 36.somethingp.


Noncom, I understand what you mean. If I had panels I could probably use about 10-20% of the "free" energy as it was produced as I'm at work all day Mon-Fri. My electricity bill would reduce by maybe about £30-£35.

However, the FiTs payment would more than cover the cost of the electricity I'd have paid for (assuming I would earn more than £300 per year from it).

Therefore, either, all of my electricity is "free" and I get maybe £100-£200 in "profit"...... or....... I pay £30 a month for my electric (as usual), get about £30's worth of "free" leccy and a FiT's payment of say, £500 (or thereabouts).

It just depends on how you look at it.


To really simplify it:

My annual electricity bill is £336.00 (£28pcm).

My imaginary whatevertywatt solar panels generate 1200kHw earning me:-

(1200x41.3p) + (600x3p) = (£495.60 + £18) = £513.60

I (ficticiously) manage to use some of the generated (free) electricity at the weekend and on days off, shaving off say, £36 from my electric bill.

My actual charged electric bill is now £300.

My FiT's payment is £513.60.

It's covered the cost of the bought electric AND I have £213.60 left. This is profit. And don't forget, based on last year's bill I've been paying £28 per month for my electric but only using £25's worth, so the electric supplier owes me £36. Yay!

I love my imaginary solar panels!


Noncom, I'm in the Midlands too so if you do get panels would you please let me know size, price and who please? Thanks in advance.

Poosmate,
The calculations you make above are reasonable.

However even a small system that you envisage will cost at least £10,000 from a MCS approved installer - and that is mandatory!

If you have to borrow £10,000 you will be lucky to get a rate of less than 6%. So £600 a year in interest before paying back the £10,000. If you have money in the bank you will be losing about £300 a year after tax(compounded)

Then over the life of the system there will be some maintenance required. Some websites say it is essential to clean the panels of bird droppings/grime etc.

It seems reasonable to assume that in the very long term it will be a good investment - but it is long term.

3.99kW System in Scotland for £17,500-£18k*

If I was from North Yorkshire I may have been able to have found you a price from there.

*not currently a MCS Approved company.

Thanking you

Tesco Energy £15,000: http://www.tescohomeefficiency.com/electricity-pricing/

You might want to discuss modifying the system with them, though - it's over the 4KW limit for the top FIT payment rate for some bizarre reason.

I've had a quote for about £15k for a 3.7kwp set up, split over two sides of the roof, supplied and installed with two inverters, and an export meter fitted also. Seems quite good and if the figures for producing are anything to go by, then it looks very interesting. I have another couple of quotes still to get so I'm looking forward to getting these to see what the competition is like.
There is no panels installed in the area, so I'm hoping I may be the first!!

Did the quote include an estimate of the annual output in kWh?

Be interesting to see what they expect in Western Scotland.
