"An average 20kg solar panel contains 1/2 kg of silicon"

A 200 watt solar panel is one sq metre ie 3 - 4 kg of silicon as the silicon metal has to be processed to polysilicon, power cost is the most important consideration in making components for solar panels and Australia is 10 times more expensive than Asia.

"1.4 MT of silicon metal are required to produce one (1) MT of polysilicon suitable for crystalline silicon PV"
"A standard silicon solar cell with a thickness of about 200 micrometers would require around 3-4 kilograms of silicon per square meter"
