The Supreme Court rejected the government's appeal on a previous ruling deeming changes to the solar photovoltaic (PV) feed-in tariff (FiT) "unlawful" on Friday 23 March. The decision brings to an end the uncertainty about what rates developers who installed solar PV schemes since 12 December 2011 would receive; installations of up to 4kW will now receive the original 43p/KWh rate. The judgement has caused speculation about whether or not the scheme will exceed its budget this year, and speculation has surfaced that the government is likely to cut the tariff again. Responding to the decision energy and climate change secretary Ed Davey said the government was "disappointed", but confirmed a line is now drawn under the case. Davey said the Department of Energy and Climate Change (DECC) will now focus its efforts on "ensuring the future stability and cost effectiveness of solar and other micro-generation technologies for the many, not the few."
