Technical FAQs 4
Are solar panels toxic?
For all solar panel types, the concentration of toxic chemicals is significantly below EPA values for screening health of air, soil, and water. Solar power is improving human health by reducing our reliance on electric power sources that emit toxic chemicals such as sulfur dioxide, nitrogen oxides, and fine particulate matter.
Do solar panels leach toxic metals?
While solar panels may contain small amounts of toxic metals like cadmium, silver, or lead, working solar panels do not leach those toxic metals. They have a strong encapsulant that prevents leaching. Cadmium telluride photovoltaic cells are sealed between two sheets of glass to protect the semiconductor materials from the outside environment.
What are solar panels made of?
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?
What materials are used in solar panels?
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.
