    Have a client who's interested in having some panels installed at his business premises in order to benefit from from import/export tariffs etc etc.


    Anyone done this or have any good links to kit/benefits etc?


    Ta! :)

    Hi Sine

    That's all I do day in day out.

    Upto 4Kwp he will be paid 41.3p for every unit the system generates and he will make further savings if they are all used in the property. This payment is fixed for 25 years and is tax free.

    4kwp is around 20 modules and will cost somewhere between 13 to 16k it will take up 28sq metres of roof space.

    A 4Kwp system installed in the South West should generate somewhere around 3800 Kwh's

    So he should receive about

    3800 x 41.3 £ 1569.40
    3800 x 11.0 £ 418.00 assumed purchase price of each Kwh

    Tot per year £ 1987.40

    He has to use an accredited installer, which is what I am to benefit from the feed in tariffs.

    Where is he based ? pass the work my way for a nice drink !

    Modules are guaranteed for 25 years

    Hi Stu, jobs in Cheshire but it's only an enquiry at the mo.

    13-16K outlay for a 2K annual return might kill it though, seems a long payback till they break even never mind make a profit?

    Stugadget any more info please?

    How do U pesuade your customers to part with 15K with only a 2K payback per year?

    Vast majority of customers are retired or semi retired with some money in the bank.

    How much would interest would £15k earn you in interest each year and remember that the income from the solar PV is tax free.

    Also as electricity prices increase so do the savings and the system will still be running long after it has paid for itself.

    The answer is it doesn't make financial sense and never will. That doesn't stop the Government propaganda brainwashing a few gullible/vulnerable people, or people mistakenly thinking they are 'doing their bit for the planet', or people whose financial logic brain chip gets shorted by people spouting BS like above!

    Doesn't make financial sense ?

    So if I can install a 2.16 Kwp system for around £8500

    This will generate about 2000 Kwh's per year.

    Payments will be

    2000 x 41.3p = £ 826.00
    1500 x 12p = £ 180.00 Own use *
    500 x 3p + £ 15.00 Exported onto grid *

    * estimated.

    Total income savings £ 1021 per year tax free. Just over eight years and systems paid for if not before as how much will electricity per Kwh be in eight years time ?

    So £ 1000 per year on an eight grand investment thats a good return on investment isn't it ?

    The 41.3p is guaranteed for 25 years and is linked to the retail price index.
     
  15. I dont think that figures are too bad at all for domestic customers but dont make too much business sense.
    I think they are a great idea but they are way too ugly to consider.
    Those solar roof tiles look like a good bet but not sure about their output.

    Do they break easy, what if kids throw stones or a football hits it?

    Per metre square output is about the same but cost if much more !

    Stones will probably damage them.

    They are tested with Golf balls at a high velocity to simulate heavy hail.

    Stugadget said : The 41.3p is guaranteed for 25 years and is linked to the retail price index.

    This is not stictly true the 41.3p is only fixed for around two years and decreases by 7% per year, every year thereafter for the 25 year period. Also the export rate is less than 7 pence per KWhour.

    You can only get the FIT (Feed in Tariffs) rates by using an MCS approved contractor who in turn has to use MCS approved equipment, have an MCS paperwork system, sign up to the real code, pay gemserv annually and per project,and so on and on and on.
    There will also be FIT rates in the future for heat pumps and solar thermal hot water.
    As a rough guide with qualifications it costs around £5000 to get MCS status for three renewable technologies plus £1300 for inspection day alone.

    Hi Black Fox

    As an MCS Approved contractor, and have been for the last 2 and half years I know my facts which I am afraid you do not.

    The 41.3p per unit is fixed for 25 years. Every one who has an installation in the first two years will receive the 41.3p for 25 years. Those that sign up in year three get 7% less 37.8 fixed for 25 years and year 4 is 7% less again fixed.

    Why did you mention 7p as I said you will receive 3p for every unit exported.

    I also should mention my figures are based on a installation on an existing building with the system size of up to 4kwp.
