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.

Are there recycling facilities for solar panels with antimony containing glass (spacg)?

The MNRE has pointed out that the recycling facilities for solar panels with antimony containing glass (SPACG) at the end of life of solar panel is not yet available in the country.

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.

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
