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.

Is antimony used in Photovoltaic Glass?

The flame-retardant sector currently accounts for around half of end use of antimony.“The use of antimony trioxide as a clarifying agent in photovoltaic glass is a developing trend, and it is expected to maintain rapid growth in the coming years,” Kang said.

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.
