    Just checked ours and we've covered 27% of the cost in the first 18 months, again not including electricity saving. Taking electricity savings into account it is over 35% cost recouped. With RPI increasing FIT payments I'd estimate that it will be well under 5 years for full payback.

    What numbers are you using to get over 8% of cost in 18 months just from electricity savings? Sounds incredibly high.

    Hi

    Jim's return, as stated, is derived from the FiT payments and excludes the electricity savings ....

    No, you are wrong.

    He stated 27% for FiT and over 35% including electricity savings.

    Hi

    You're correct, I remembered the '27% excluding' and didn't re-read the rest .... anyway, assuming a typical/decent saving of £150 to £180 over 18 months then 8% would describe a system price in the range of £1875 to £2250, whereas 8% over 18months on a typical 4kWp system price ~18 months ago (~£10k?) would represent an annual saving of ~£533/year which would just about represent 100% self consumption (if you inflate the cost of electricity a little - ie ~14p/kWh !) ....

    I agree, more than a tad optimistic unless there's a massive baseload (at least 3.6kW) !! ... I guess that Jim needs to revisit the payback calculation ... :D;)

    Apologies

    No problem.

    27% over 18 months is a great return, beating mine.

    The over 8% for electricity did seem a lot, why I asked. Was just interested to know the numbers or reasons.

    Sounds like you are looking at a great payback time :D

    I'm not far behind @ 24% in 18 months :)

    Cheers

    We are very pleased with ours too.

    We've had just over 20% of our purchase cost back in 15 mths (not counting reduction in electricity bills) and this qtr should be really good and is looking like taking us over the 30% mark!!!
