- Upgraded metallurgical grade silicon cost $2 per kilogram [5]
- $40-200 per kg for solar grade silicon - [6]
- Polysilicon is $15/kg, and 5kg is needed per kw of PV panels - [7]
- About 660g of silicon per 60 cell panel - [8]. This does not include wasted silicon starting from uncut crystals
- Cost of silicon in a solar panel is 20 cents per watt in 2012 - [9]. Silver contacts cost half this amount. Nickel and copper contacts are higher performance and lower cost but more complex to manufacture.
