Technical FAQs 4

Does solar glass contain antimony?

However, the composition of solar glass varies, especially concerning antimony (Sb) content, depending on the production method. Antimony is used to enhance the performance of patterned solar glass but introduces environmental and health concerns, complicating recycling efforts.

Why is antimony a problem for solar glass recycling?

Currently, the import of modules from outside the EU with variable antimony content drastically complicated recycling efforts of solar glass. Indeed, antimony poses environmental and health risks and can lead to undesirable interactions with the manufacturing process. To address this issue, ESIA members are calling for:

Should antimony-free glass be used in New solar panels?

“ROSI advocates for antimony-free glass in new solar panels installed in Europe, notably through the Ecolabel directive, as it opens more doors for recycling,” he explained.

How can the US reduce antimony levels in solar glass?

The U.S. could also implement a threshold for antimony levels in solar glass, gradually reducing the allowable amount over time. This would encourage manufacturers to phase out the use of antimony in their production processes and facilitate more straightforward recycling in U.S. facilities.
