installations, the market matured, bringing down various «soft
costs» (which is basically where US &
German solar

costs for subsidizing new PV
installations in 2009, based on initial industry estimates for new
installations of around 700 MW, could be as high as $ 10bn over the course of the 20 - year FiT programme.
