Many countries have 'subsidies' i.e. funds derived from general taxation to
promote the use of PV. Personally I have no time for subsidising loss-making
sources with public money. It's madness for a utility to pay their customer
more for the electricity they supply than they pay for what they use use (
such as is the case with micro-generation in Germany ). I think the most
generous grants are indeed in Germany which isn't even a good location for
insolation. It might be a good market for you though.

Sometimes technology needs policy support to develop. That is the case
with PV now, yet I thought it will not be long, whether from market or
technology aspect. We expect the cost of PV be close to thermal power in
2015.

Informative site, thanks.

On what technical basis ? I certainly do not see any such outcome. PV solar cells
aren't exactly new technology and the alleged 'breakthrough' thin film cells have
half the conversion efficiency of today's wafer types. Solar thermal will beat
you
hands down anyway.

I think it's not thin film cells, but crystalline silicon cells,
although in the long run thin film cells may prevail. Solar thermal is
more practical than PV now, economical and with a high efficiency, just
the form of energy is limited.

Why tax gasoline to promote low consumption vehicles (as in Europe)?
Ask G.M. (and the taxpayers that will be paying for it)

Sometime the oil barrel price will tenfold. Some will be ready.
