12. Feed In Tariff (FIT)
Typical Example Of Benefits With 20 kWp Solar PV System:
 A. Generation income
Tariff 13.03p per kWh
x Annual generation 18,000 kWh = £ 2,345.40
 B. Export income
Earn 4.5p x (estimated at 50% of generated amount) kWh = £ 405
 C. Fuel bill savings
Save 10p per kWh x 17,000 kWh = £ 1,700
Total system benefit per year A + B + C = £ 4,450.40

13. Solar (PV) Panels
 Typical Investment & Payback 20 kWp Solar PV System
 Installation cost (£ 32,000) / Annual benefit (£ 4,450.40)
= 7.2 year payback on investment
 The Feed In Tariff lasts for 20 years & all calculations are
made without inflation adjustment (which will be made) and
increased imported electricity costs. Therefore the benefit
total is likely to be considerably more.
