Typical Financial Benefits
A typical house uses 4000 units of electricity per year @ 12.5p* per unit. The average annual electricity cost is therefore £500. A 4kWp costs around Solar PV system will generate around 3335 kWh* of electricity.
Assuming half of the energy produced is used in the home (for free) and the rest sold back to the grid:
- FIT income = 43.3p x 3335 = £1,443
- Export tariff income = 3.1p x 1250 = £51
- Avoided electricity = 12.5p x 1250 = £208
Total income and savings in the 1st year: £1,702
These payments are index linked and guaranteed for 25 years.
Total Benefit after 25 Years: £42,550...

Why buy now? The money to pay for the FIT Scheme is being raised by taxing the major energy suppliers. Not surprisingly they raise this revenue by charging all their customers more for their electricity. Ofgem have warned that electricity prices could soar by 60% over the next 5 years.
