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.

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.

Can antimony containing glass be recycled?

oped PV recycling technology and Antimony containing glass may be recycled without affecting its properties. The recycl ng process of 1 ton of PV panel is likely to produc Kg. of clean glass and 14 Kg of contaminated glass. The recycled glass can be used to produce new SPACG However, in case there are no facilities to recycle, the opti

Should PV module manufacturers be required to disclose antimony compounds?

To address these challenges, the ESIA Recommendation paper suggests that the European Union should consider mandating PV module manufacturers under the upcoming Ecodesign regulations to disclose the composition and manufacturing process of solar glass, including additives like antimony compounds.
