Why Solar Panels Can't Go in the Trash

Understanding the environmental risks that drive New Jersey's recycling requirements.

Environmental Risks of Improper Solar Panel Disposal in NJ

Solar panels are great for the environment while they're producing clean energy. But at end of life, they require special handling because of the materials they contain.

Lead in Panel Soldering

Most crystalline silicon solar panels use lead-based solder to connect cells. When panels break down in landfills, this lead can leach into soil and groundwater.

Health Risk: Lead is a neurotoxin that can cause developmental issues in children and health problems in adults. Even small amounts of lead contamination can have lasting effects.

Cadmium in Thin-Film Panels

Cadmium telluride (CdTe) thin-film panels contain cadmium, a toxic heavy metal. While these panels are less common in residential installations, they're still found in many homes.

Health Risk: Cadmium exposure can cause kidney damage, bone disease, and is classified as a human carcinogen by the EPA.

Other Hazardous Materials

Various panel components may contain other concerning materials including certain flame retardants in backsheets and chemicals in the glass coatings.

Health Risk: These materials can persist in the environment for decades and accumulate in the food chain.

What Happens When Panels Go to Landfills

When solar panels are dumped in regular landfills instead of being properly recycled, a chain of environmental problems can begin.

Glass Breakage

Compaction in landfills breaks panel glass, exposing interior components

Chemical Leaching

Rain water carries heavy metals from broken panels into surrounding soil

Groundwater Contamination

Contaminants can reach underground water supplies used for drinking

Long-Term Persistence

Heavy metals don't break down—they remain in the environment for decades

Your Liability if Panels Are Improperly Disposed

Under New Jersey environmental law, property owners can be held liable for contamination that originated on their property—even if a contractor was the one who improperly disposed of the panels.

  • Cleanup costs can be significant and may require professional remediation (based on similar state Superfund cleanup cost data)
  • Property devaluation if contamination is discovered during a sale
  • Legal liability to neighbors or future owners who are affected

The Good News: Proper Recycling Solves This

When panels are properly recycled at certified facilities, hazardous materials are safely extracted and processed. Up to 90% of panel materials can be recovered and reused—including valuable silver, copper, and silicon.

By working with a qualified contractor and getting your Certificate of Recycling, you protect both the environment and yourself.
