The new rates for the feed in tariff have just been anounced. The new rates apply to all systems already installed and those systems installed before April 2012. This means that a South West Free Energy solar PV system of no more than 4kWp installed on a house will pay 43.3p per kWh up approximately 4.8% from 41.3p per kWh. Rates for all other system sizes go up by a similar amount.
