Lead: Often used in soldering electronic components. A standard solar panel can contain about 14 grams of lead. The solar industry is making efforts to reduce lead use significantly by 2026, aiming for less than 50% of panels to contain lead-based solder and reducing its use in cell manufacturing to under 20%.
While solar panels use mostly common materials with very low toxicity—glass and aluminum account for over 90 percent of a solar panel’s mass—silicon-based solar panels use trace elements of lead for antireflective coating and metallization on solar cells inside the panel.
Some glass products, such as fine crystalware and certain types of lenses, may still contain lead. These products often require the unique properties provided by lead oxide, and manufacturers may argue that the benefits outweigh the risks. However, many everyday glass products, such as: are increasingly being manufactured without lead.
The solar industry is making efforts to reduce lead use significantly by 2026, aiming for less than 50% of panels to contain lead-based solder and reducing its use in cell manufacturing to under 20%. Cadmium: Found primarily in thin-film solar panels (cadmium telluride, CdTe), which make up about 2% of the market.
