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.
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.
