Yes, solar panels can be recycled. Most panels contain recyclable glass, aluminum, copper, plastics and semiconductor materials. Glass accounts for about 75% of a typical panel's weight. Solar panels should not go in a standard curbside recycling bin. Homeowners should contact the original installer, a specialist PV recycler, or their state or local environmental agency.
The U.S. recycling network is still developing. In 2025, the Solar Energy Industries Association reported that its participating recycling and refurbishment partners had collection and processing sites serving major U.S. regions.
Solar Panel Recycling at a Glance
| Question | Answer |
|---|---|
| Can solar panels be recycled? | Yes, although access varies by location. |
| Can solar panels go in the curbside recycling bin? | Usually no. Use a specialist recycling or take-back service. |
| What materials are recovered? | Glass, aluminum, copper, plastics, silicon and some specialty metals. |
| Can working panels be reused? | Often, if they still produce electricity and meet safety requirements. |
| Are solar panels hazardous waste? | Some discarded panels may qualify as hazardous waste because of lead or cadmium content. |
| Who should arrange recycling? | The installer, solar company, specialist recycler or local environmental authority. |
What Parts of a Solar Panel Can Be Recycled?
Most modern solar panels are crystalline-silicon photovoltaic modules. They usually contain:
- Glass, which makes up about 75% of the panel's weight
- Aluminum, usually from the frame
- Copper, including wiring and electrical connections
- Silicon solar cells
- Plastic polymers and backsheets
- Silver, tin, lead and other specialty metals
- A plastic junction box
Glass, aluminum and copper are generally the easiest materials to recover. Silicon, silver and other metals require mechanical, thermal or chemical processing at a suitable facility.
Thin-film panels use a different design. Cadmium telluride panels, often called CdTe panels, can be processed to recover cadmium and tellurium, along with glass and copper.
How Are Solar Panels Recycled?
A typical recycling process includes:
- Removing the aluminum frame and junction box
- Separating the glass from the laminated solar cells
- Shredding, milling or heating the remaining materials
- Separating glass, metals, plastics and silicon
- Purifying recovered materials when the facility has the required equipment
The process depends on the panel design. Mechanical recycling is common for crystalline-silicon panels. Thermal and chemical processes can recover more materials and produce higher-purity outputs.
Can Old Solar Panels Be Reused Instead of Recycled?
Yes. Reuse is usually preferable when a panel still works safely. A used panel may be refurbished, resold or installed in a less demanding setting, such as an off-grid structure, remote power system or electric vehicle charging project.
Reuse may require additional electrical, building, fire and grid-interconnection checks. A panel that is cracked, water-damaged, delaminated or producing very little power may not be suitable for reuse. A qualified installer or recycler should assess it.
How Do You Recycle Solar Panels at Home?
For a residential solar system:
- Contact the original solar installer. Ask whether the company offers removal, take-back or recycling services.
- Identify the panel type and manufacturer. The model number is usually printed on the back of the panel.
- Ask whether reuse is possible. Working panels may be worth more when refurbished than when shredded.
- Contact your state or local environmental agency. Accepted facilities and disposal rules vary by state.
- Request a quote from a specialist PV recycler. Provide the number of panels, panel type, location and condition.
- Arrange professional removal. Panels are fragile and may remain electrically active in sunlight.
- Confirm the destination. Ask whether the panels will be reused, recycled or disposed of, and how damaged materials will be handled.
The U.S. Environmental Protection Agency recommends contacting the installer or state and local environmental agencies for disposal and recycling guidance. The EPA also identifies the Department of Energy and Solar Energy Industries Association as sources for finding recycling options.
Should You Throw Solar Panels in the Trash?
Do not put solar panels in household trash or curbside recycling unless your local waste authority specifically tells you to do so.
Discarded panels may contain small amounts of lead, cadmium or other regulated metals. Some panels pass hazardous-waste testing, while others fail it, depending on their materials and construction. The legal classification can also vary by state.
Do not break, crush or dismantle a panel yourself. Protect damaged panels from further breakage and tell the installer or recycler if a panel is cracked, burned or otherwise damaged.
How Much Does Solar Panel Recycling Cost?
Recycling often costs more than landfill disposal in the United States because transportation, handling and processing add expense. The U.S. Department of Energy previously estimated recycling costs of about $15 to $45 per panel, compared with roughly $1 to $5 per panel for landfill fees, excluding transportation. Actual prices vary by location, panel condition, quantity and recycling method.
For a small residential system, removal and transportation may cost more than the material value of the panels. Recycling becomes more practical when panels are collected in larger quantities or when a manufacturer or specialist recycler offers a take-back service.
Are Solar Panels Likely to Be Recycled in the United States?
Yes, but the system is still developing. The United States has PV-specific and general recycling facilities that can process solar panels. Access is not yet as convenient as it is for glass, aluminum or some types of electronic waste.
The Solar Energy Industries Association operates a National PV Circularity Program with recycling and refurbishment partners. Its partner network covers major U.S. geographic regions.
Best Option for End-of-Life Solar Panels
Use this order:
- Repair the system if the problem is an inverter, wiring or mounting component.
- Reuse or refurbish the panels if they still operate safely.
- Send unusable panels to a specialist PV recycler.
- Use compliant disposal only when reuse and recycling are unavailable.
