Feed in tariff rates are based upon the amount of electricity generated and also upon when the system was installed. As is evident from the government table and its scheme, the feed in tariff rates have been reduced from April 1, 2012. The new table scheme is applicable to all feed in tariff qualifiers.
Installations with a capacity of less than 4kWh are entitled to a feed in tariff of 21p per kWh for the year 2012, and a baseline degression of 10 per cent every six months. The table clearly states that in July 2012, the feed in tariff rate will 13.6p, and according to the tariff table in October 2012, 12.9p with steadily decreasing rates bi-annually. For stand-alone installation scheme, the rates are 8.9p in April 2012, 4.7p in July 2012, and so on in the table.
To be eligible for feed in tariff rates and scheme, new installations, up to and including 250 kW, need to meet energy efficiency requirements. They must have an energy performance certificate of Level D and above. Multi installation higher feed in tariff rates range from 16.8 per kWh for new build under 4kWh installations, but these rates are applicable only where the feed in tariff generator has over 25 installations in different sites, and receives feed in tariff payments for all of them.
Feed in tariff rates have dropped considerably from the original levels of 43p per kWh, since the government acknowledged that they have overshot their feed in tariff budget scheme. There has been a rapid rise in the number of installations, and over 1,00,000 solar PV panels were installed since the new lower rates were announced last October and before they came into effect through the table scheme. The rise in the solar PV manufacturers and the drop in the prices of the equipment have led to a surge in the scheme which are entitled to feed in tariff rates table.
