Despite their serious potential to lead the charge for durable green energy, solar panels have a limited life span. Due to a current lack of understanding regarding recycling and reuse management standards, owners and installers don't have clear information on how to properly dispose of unwanted solar panels. 

​

Reuse is preferred over recycling for working panels as it promotes equity. Promoting the reuse of solar panels allows people to purchase solar panels at lower cost, ensuring greater access to green energy, and serving as a form of source reduction. For solar panels to be reused, they must have active safety certifications, verified on CEC's solar equipment list.

​

When solar panels are no longer working or ineligible for reuse, they become regulated by a different state agency. The California Department of Toxic Substances Control (DTSC) regulated unwanted solar panels under the Universal Waste regulations, similar to electronic waste. Solar panels destined for recycling or disposal need to go through authorized handlers.

DTSC has classified organizations allowed to handle solar panels separate from the organizations allowed to recycle or treat them. Handlers are authorized only to transport solar panels. The list of DTSC-approved handlers includes organizations for distribution, warehouses, and reuse outlets. To recycle solar panels, handlers must apply for additional certification and follow specific regulations from DTSC for treatment. For a list of California universal waste recyclers that treat solar panels, please visit DTSC’s List of Recyclers that Treat [Solar Panel] Modules webpage.
