There are 5+ types of solar panels. Cadmium-Telluride solar cells, the ones criticized for toxic components, only make up about 5% of all solar panels produced.
Most conventional solar panels are made from Silicon. Silicon is produced by refining sand. It's not toxic and makes up objects that we use every day (i.e. windows or cups).
