Feed-in Tariffs are not a form of Renewable Energy and became available in Great Britain on 1st April 2010.
Under this scheme energy suppliers make regular payments to householders and communities who generate their own electricity from renewable or low carbon sources such as solar electricity (PV) panels or wind turbines.
The scheme guarantees a minimum payment for all electricity generated by the system, as well as a separate payment for the electricity exported to grid. These payments are in addition to the bill savings made by using the electricity generated on-site.
What you save depends on your electricity usage but a 2 kWp system could earn around:
£700 per year from the Generation Tariff
£25 per year from the Export Tariff
£110 per year reduction in current electricity bills.
This gives a total saving of around £830 per year.
This assumes 50% of the electricity generated is exported.
Advantages are you save money although this needs to be weighed against installation costs. Currently prices range from £5000 to £10,000 for a Photovoltaic (PV) system. Feed-in tariffs should be seen as a long term investment.
