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.
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.
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.
