Marie Said:

Do Solar Cells contain anything toxic?

We Answered:

Cells manufactured in the last few years will generally be ROHS compliant, and contain no lead in the solder. Our panels were manufactured in 2006, and have the "no lead" icon on them.

The processing of silicon wafers involves some toxic substances, but the finished cells themselves don't have these products in them. Silicon tetrachloride is a raw ingredient from which a refiner makes polysilicon. But the finished silicon ingot is immensely pure, no chlorine left in it.
