Financial return

Feed In Tariffs

The Feed-In Tariff Scheme is a government-backed guarantee to pay you for electricity consumed for a period of 25 years. This has now increased the attractiveness of renewable energy installations.

The annual return from the PV investment would be around £1400*. This is calculated from the combination of £1100 income plus £300 avoided energy cost.

The figures are year 1 and before inflation and fuel price escalation has been applied. With inflation and fuel price escalators incorporated into the returns, and the returns aggregated over the full length of the 25 year tariff, a total net of income of £16 per month is achieved. If you include the £87.76 you would have had to spend on the electricity you would have had to buy in, the net gain is £100 per year.

If you compare this to not having the PV, you would have had a net outgoing of £104.

If you reduce your energy consumption you will increase your rate of return.

FITS INCOME IS TAX FREE and if you could find a bank account with interest rates at 5%, you would achieve LESS than you would by investing in a FITS-backed PV Installation.

As fuel prices will continue to rise, your payback will reduce and your investment will increase in value.

Your house is likely to increase in sales value with a FITS registered ZEDroof a beautiful rooftop conservatory.

All calculations are based on the 'European Union Joint Research Council' PVGIS solar irradiation data. This data is average data over a 10 year spread and it is possible that actual output will vary year on year. Rates of return are for FITS backed PV costs only. Full data set and methodology available on request.

Payback period

Due to the design of the ZEDroof and the ability to utilise the tariff schemes, an occupier will always be better off financially with a ZEDroof than without.

The payback period for 2 different scenarios has been calculated:

• for a lump sum capital investment and,
• for a loan or mortgage financed installation

The Annual Net benefit has been calculated as follows:

Both scenarios show a positive Annual Net Benefit from year one of having installed a ZEDroof. This means that as soon as you have installed a ZEDroof system, you will be better off each year, aswell as having guilt-free hot water and electricity. This annual net benefit also reduces the time it takes to pay back the investment in the renewable technology.

For a capital invested ZEDroof, the payback period could be as little as 8 years.

For a mortgage or loan financed ZEDroof, the payback period will be more like 18 years.
