If you're really worried about it, buy a panel from europe, the polysilicon (90% of the energy) comes from hydro, wind, and nuclear powered countries.

Even if all the money for a solar module went to coal generation at chinese or indian prices and nothing else it would pay back that power in under two years.

If the only activity involved in making PV was to spend the entire system cost on lignite and burn it directly at the mine front, it would *still* produce more energy in its lifetime than putting the coal in a coal plant.

It's absolutely laughable that you think you can keep spouting this ridiculous lie.
