Does anyone have any good numbers for the amount of energy needed to
make a PV array vs. the power it delivers? A proper estimate should
include *all* the energy costs, i.e. manufacturing the chemicals needed,
the fact that sawing discards a siginificant portion of the silicon
which took energy to refine up to that point, etc.
