As a comparison, I read somewhere that it takes 1
barrel of oil to bring up 100 barrels of oil in the Middle East and 1 barrel of
oil to bring up 10 barrels of oil in the US. According to the EERE
report referenced below, PV falls in the middle at 1 watt of electricity to
produce 10 watts to 29 watts. Of course, oil numbers are falling and PV
numbers are increasing.

Payback for PV Panels...
It's an old arguement; how long does a PV
system have to operate to recover the energy—and
associated generation of pollution and
into making the system, in the first place? This NREL site seems to have a
pretty good answer.
