The vast majority of photovoltaic solar panels are either crystalline silicon or cadmium telluride. Crystalline silicon PV modules are 77% glass, 10% aluminium, 3% silicon, 9% polymers with less than 1% copper, silver and tin and less than 0.1% lead. Solar panels are made of: Are there health concerns with commercially produced PV modules?
In solar panel manufacturing, lead is typically combined with tin to form an alloy used in soldering to connect various components. The metal is flexible with a low melting point, making it ideal for creating electrical connections within the panels.
Each standard solar panel contains about 14 grams of lead 1. That means about 4,400 tons of lead were used to make the 92 GW of solar panels installed in 2018 2. This is a large amount but still comparatively small relative to the 9,000,000 tons used for batteries each year.
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.
