In 2022, at 2.2 grams per watt at $17/kg – the price is $0.04/watt. So, the real cost per watt of silicon has come down by 96.7%. This article was ameded tno change the unit from kg to t in the following: In 2004, we deployed 1,044 MW of solar power, using just over 16,000 t of silicon globally.
The prices of silicon wafers are mainly influenced by two parameters: silicon usage per wafer and silicon price per kg. Although silicon prices peaked at 30 USD/kg in 2008, they have remained relatively stable between 15 and 30 USD/kg (see Fig. 5 ). Cost reductions for silicon wafers primarily focus on reducing wafer thickness and sawing losses.
Wafer prices are strongly linked to polysilicon prices. Current (June 2015) spot prices for wafers are about 1.01 USD/wafer, with polysilicon prices at around 15.7 USD/kg.
Current (June 2015) spot prices for silicon wafers are about 1.01 USD/wafer.\ Polysilicon prices are around 15.7 USD/kg . After many silicon producers shutting down due to an oversupply, prices were estimated to stabilize and rise slightly to a price of about 20–25 USD/kg .
Thanks to advancements in technology, solar is now powering the world with a lot less silicon. Research by Fraunhofer ISE shows that since 2004, the material usage of polysilicon per watt of solar cell has dropped by approximately 87%. The data suggests that in 2004, 16 grams of silicon were needed to produce a single watt of solar cell.
If we assume that this 545 watt panel uses 2.2 grams of silicon per watt, we get 1,199 grams per module. That’s approximately 360% higher output per solar panel — using only half of the silicon! Of course, we’re going to use massively more silicon in 2023 than we did in 2004.
