well on the prices they quoted the other day its does look very dodgy ! Would the Government raise FIT rates if wholesale price increases ? From what I understand alot of PV manufacturers have gone bust or existing on government support (chinese PV) hence why USA is impossing a tax (or the sort) on subsidise cheap chinese PV panels ! If world production reduces then prices could increase. There is no fat in the DECC model to allow for any deviation, 5% return just wont sell. Customers want a 10 year or less payback, the warranties etc are around that term.
