How Solar Panels Are Made LetsGoSolar

Silicon can be mined from quartzite mica and talc but sand is its most abundant ore source. The silicon in solar panels is manufactured through a reduction process in which the silica is heated with a carbon material and the oxygen is removed leaving behind purer metallurgical-grade silicon.
