There are different methods to recycle solar panels, which can include some or all of the following three steps:Removal of the frame and junction box;Separation of the glass and the silicon wafer through thermal, mechanical or chemical processes; and/orSeparation and purification of the silicon cells and specialty metals (e.g., silver, tin, lead, copper) through chemical and electrical techniques.

At least one U.S. manufacturer runs dedicated recycling facilities for thin film panels which recover the semiconductor material (cadmium and tellurium) in addition to glass and copper. You can search for solar panel recycling options on the following organizations' websites:
More than 85% percent of a solar photovoltaic (PV) module is made of materials we already know how to recycle, like aluminum and glass. However, solar panel recycling—and most recycling overall—is not currently cost-effective or widely adopted. Making solar module recycling ubiquitous will require a combination of technology and policy innovation.
Other components of a solar power system may include inverters, racking, and battery backup systems, which may also be recycled. Inverters may be able to be recycled with electronic waste, and racking may be recycled with similar scrap metals. Battery-based grid energy storage systems may be handled with current battery recycling programs.
Making solar module recycling ubiquitous will require a combination of technology and policy innovation. To make a larger impact on reducing waste and other environmental impacts from solar technologies, actions need to be taken before a module is even made.
Find out how solar panels are recycled and where to take your end-of-life solar panels for recycling. On this page: Waste from end-of-life solar panels presents opportunities to recover valuable materials and create jobs through recycling.
SERI has created a PV Panel Recycling Working Group comprised of experts from the reuse and recycling vendor, manufacturer, customer, scientific expert and public interest representative communities that has been meeting since fall of 2020.
