That's a self-defeating statement: industry would have to be running
to make the photovoltaics.
Which can be used to power your calculator and keep your water hot in the
summer. Solar panels are not the solution.
That depends purely on price.
And the cost of making them depends of the price of energy.
Unless you're talking about some other technology....
Pv's need very pure silicon, and it takes _a lot_ of energy to
make pure silicon: so much in fact that it's questionable
if a pv produces more energy than was used to make it.
