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.
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.
Research by Fraunhofer ISE shows that in 2004, 16 grams of silicon were needed to produce a single watt of solar cells. By 2021, that number had shrunk to just over 2 grams. That year, when the world’s largest solar farm – at just over 5 MW – was switched on in Germany, it was using 150 W solar panels.
According to Bloomberg, 268 GW of solar was deployed in 2022, which is over 250 times more capacity than what was deployed in 2004. At 2.2 grams per watt, the 268 GW used approximately 590,000 ktg of silicon, or 35 times more silicon than was used in 2004. The volume of silicon used is only half the story.
For the wafers described here, the physical wafer plus wafer slicing kerf loss brings the silicon cost to $0.217 per monocrystalline Cz wafer and $0.236 per multicrystalline DS wafer. The kerf losses from ingot cropping, squaring, grinding, and polishing account for only about 5% of the total net kerf loss.
Our median estimated MSPs of $14–$23/kg (Siemens) and $14–$19/kg (FBR)—which include all-in production costs plus sustainable margins—tend toward the higher end or above the 2016/2017 global ASP for solar grade polysilicon of $14–$18/kg (Osborne 2017).
