There are several ways to decompose used photovoltaic panels

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.

How do I dispose of solar panels?

Homeowners with solar panels on their houses should contact their state/local recycling agencies for more information on disposal/recycling. Federal solid and hazardous waste regulations (i.e., the RCRA requirements) apply to solar panels when they are discarded.

How are solar panels recycled?

Once the solar panel has been properly dismantled, the different components are recycled properly using different methods, for example: Solar cells: Solar cells are typically recycled by melting down the cells and extracting the melted silicon (or other valuable materials). This process is called thermal recycling.

Do solar panels have a waste disposal plan?

Despite the presence of environmental awareness, California, another world leader in solar panels, also has no waste disposal plan. At the end of their useful lives, only Europe requires the manufactures of solar panels to collect and dump solar waste.

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.

How much solar PV waste will be recycled by 2050?

The worldwide solar PV waste is estimated to reach around 78 million tonnes by 2050. The current status of the EOL PV panels are systemically reviewed and discussed. Policy formation involving manufacturer's liability to inspire recycling of waste solar panels. R&D needs acceleration allowing researchers to resolve issues in PV module recycling.
