I'm so tired of electrical vehicles of any sort being described as "non-polluting." They're only non-polluting if the source of the charge is non-polluting, which it most likely isn't.

These guys use solar panels which eight out of ten trolls agree are relatively nonpolluting.

You got me, Pekar; I missed that. It was intended as more of a general comment, as there seems to be a general perception that electrical cars are non-polluting -- which, I maintain, the vast majority aren't. This one is, though, which is delightful.

Oh, and could you define "troll" for me?

Neat project.
That being said...
Show me how to make a solar panel with out polluting.
Question: With todays technology, how long does a solar panel need to generate for to create more energy then was used to manufacture it? This is not trolling, but a question to ponder.

Hello matthew_klienmann,
Most solar cells will produce enough electricity to "pay back" the power used to make them in about 5 years or less.
From Wikipedia See the article for two annotations.
The variance is 1 to 30 years for energy payback, depending on at least the efficiency/type of the cell and possibly other factors.
Basically, they last a lot longer than it takes for them to pay themselves back energy-wise.
Cool idea!
