Technical FAQs 4

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.

Is antimony in solar glass a problem?

Despite ROSI’s success in the area, Luxchemtech’s Palitzsch warned that the presence of antimony in most solar glass is still a problem when it comes to recycling.

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.

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.
