– Rainwater is reused and treated for either potable or grey water use

Benefits Costs

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

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.
