EXAMPLE – retrofit
Assume – Household annual consumption is 4000kwh
Expect 1800kwh generated from a 2KW peak system in SW England.
50% of generated power is used in house – 900kwh
Total power purchased from REC is 3100kwh
Installation cost £10k without grants.
Cost of electricity with no PV = 4000 * 0.14 = £560
FIT from PV – 1800*0.413 = £743.4
Export tariff extra 900*0.03 = £27.00
Total income from FIT = £770.4
Total bill paid to Supplier (4000-900)*0.14 = £434
Annual income £770.4-£434 = £336.4
Actual rate of return is 743/10000 = 7.43%
