Solar Panels are Safe for Your Community

Learn about the materials in solar panels and discover how utility-scale solar facilities are safe for your community.

Key Takeaways

• Solar panels are made of materials like glass, aluminum, copper, and semiconductors commonly found in household appliances and technology.
• In the U.S., the two most used solar cells—Crystalline Silicon (c-Si) at 62% of current installations, with Thin Film Cadmium Telluride (CdTe) making up the majority of the remaining market—do not pose a danger to human health or the environment.
• Testing shows that both c-Si and CdTe panels are safe in worst-case conditions of abandonment or damage in a disaster.
