The PV glass industry uses antimony and its compounds to regulate the Fe 2 O 3 content in the patterned glass to increase the glass clarity by oxidizing ferrous oxide (FeO) into Fe 2 O 3. 22 However, its presence poses challenges for float glass manufacturers due to potential reactions in the manufacturing process.

ncept Note Print on Management of Antimony Containing Glass from End-of-Life of the Solar PV Panels1. Background An application OA No. 473 of 2017, Niharika Vs Union of India and Others was filed before Hon'ble NGT regarding use of Antimony containing glasses used in solar Photo
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.
Can Borosil remove antimony from solar glass?
Borosil has been able to successfully remove the Antimony from Solar glass. Institut fur Solartechnik SPF, SWITZERLAND, widely considered a GOLD STANDARD for testing and certification of solar glass publishes on its website, test results of solar glass from some of the top solar glass manufacturers in the world.
How much antimony is in solar glass?
World Health Organization (WHO): A limit of 5 ppb. California Environmental Protection Agency (CalEPA): A public health goal of 1 ppb for Antimony. Proportion of Antimony in solar glass is typically 0.2% to 0.3% (2 to 3 million ppb). Each PV module has a front glass weighing about 16 kg and thus an Antimony content of 32 to 48 grams.
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.
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.
