OT ? Solar panels Will they get cheaper?

Or more efficient? I understand the high cost is due to the cost of
silicon, so what is the future for the cost of silicon?

PV panels are not worth implementing in 99% of cases. Theyre only
useful for remote locations eg spacecraft. The energy payback is ok,
but the cost is outrageous. Of all the alt energies talked about, PV
will give you the least bang per buck, ie the least energy output per
dollar.

If you want solar panels, go with flat panel space heating, and forget
PV unless youre in the middle of nowhere. FPSH can get you orders of
magnitude more energy payback than PV.
