How Much Can I Earn?
A Solar installation will provide Savings for at least 20 years and a Guaranteed Income for 20 years.
Savings – if your consumption is £75/month, and you use half the electricity you generate, then you could save £450/year.
Feed in Tariff – as of 1st November 2012 the FiT is 15.44p/unit. This is Index Linked, Tax Free and Guaranteed for 20 years
Export Tariff – this is 4.5p/unit and it is assumed that 50% of the electricity generated will be exported.
Example : a 4kW Solar system installed on a property in the South of England, with a South facing roof pitched at 30°.
According to the SAP calculation this will generate 3,443kW per year. This translates to –
Feed in Tariff = 3,443 x 15.44p = £531.60
Export Tariff = 3,443 x 50% x 4.5p = £77.47
Total income =£709.07
This income is Index Linked, Tax Free and Guaranteed for 20 years.
