6 FAQs about [Solar panels contain toxic materials]

What are the toxic chemicals in solar panels?

These two intervals are times when the toxic chemicals can enter into the environment. The toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride.

Are solar panels toxic?

Solar panels are consistently characterized as non-hazardous under the EPA’s Toxicity Characteristic Leaching Procedure (TCLP) which tests leaching of toxic chemicals. Such testing creates conditions much more extreme than in the field: chopping up solar panels into tiny pieces, submerging them in an acidic solvent, then agitating them.

Are thin film solar panels toxic?

The materials used in making thin film solar panels can be toxic. These toxic chemicals are introduced into the environment in two stages of a solar panel’s lifespan – production and disposal. During production, these chemicals are gathered, manipulated, heated, cooled, and a plethora of other processes which involve human beings in every step.

What makes solar panels potentially hazardous?

Solar panels can become potentially hazardous waste if they meet the characteristic of toxicity. Heavy metals like lead and cadmium may leach at such concentrations that waste panels would fail the toxicity characteristic leaching procedure (TCLP), a test required under RCRA to determine if materials are hazardous.

Can solar panels be considered hazardous waste?

Solar panels can be considered hazardous waste under certain conditions. This typically occurs when they meet the characteristic of toxicity, specifically if they contain heavy metals like lead and cadmium at concentrations that fail the toxicity characteristic leaching procedure (TCLP).
