27/12/09 - Prince Charles has turned his eye on solar PV for his London home, Clarence House.  The Prince of Wales, a major supporter of green initiatives, is looking at generating electricity for heating and lighting by installing solar PV on this grade II listed building. The feed-in tariff will give Charles a return of 8% on his capital outlay. If planning permission is granted, the installation could become one of the largest on a house in Britain.
