How to deal with solar PV waste material?

Therefore, the methods of dealing with solar PV waste material, principally by recycling need to be established by 2040. By recycling solar PV panels EOL and reusing them to make new solar panels, the actual number of waste (i.e., not recycled panels) could be considerably reduced.

Are photovoltaic panels a waste?

Many photovoltaic panels (PVs), have accumulated as a waste and even more PVs are nearing their End-of-Life (EoL). PV waste is considered a “hazardous material” due to the multitude of precious, heavy and toxic metals employed in their construction. Nowadays, PV waste is usually landfilled or incinerated.

Should solar PV panels be recycled?

We recommend that recycling should be made commercially necessary by making manufacturers responsible for recovering materials from solar PV panels EOL. In summary, the management of panels EOL and other hazardous waste is obligatory.

Does solar PV panel EOL management exist?

Therefore, solar PV panel EOL management is an evolving field that requires further research and development. The key aim of this study is to highlight an updated review of the waste generation of solar panels and a sketch of the present status of recovery efforts, policies on solar panel EOL management and recycling.
