In this document, the DECC consults on generation tariffs to be applied to solar PV installations with an eligibility date on or after 1 July 2012 and are recommending a further reduction to solar PV tariffs from 1 July. Three alternative tariff tables are proposed. A potential review of export tariffs is also discussed and whether they will reduce the period for which tariffs for PV installations should be applied, from 25 to 20 years. The closing date for responses is: 3 April 2012
