4 FAQs about Photovoltaic panel waste sorting

How are PV panels recycled?

Today, recycling technologies for PV panels mainly focus only on harvesting the easy components like aluminium frames, electrical junction box, and, in some cases, the glass, while the rest is dumped in landfills or incinerated [3, 4]. Shredding and sorting processes dominate today's PV recycling.

How to tackle challenges in photovoltaic (PV) recycling?

The four key recommendations to tackle challenges in photovoltaic (PV) recycling are as follows: promote design for recycling (DfR); data availability; advance policy; and incentivize upcycling. DfR concepts need to be incorporated in the design phase and can be explored through innovations in the frame, material choices and module lamination 111.

What are the different types of PV panel recycling methods?

Furthermore, distinct recycling approaches are required for different PV panel technologies, including crystalline silicon (c-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and amorphous silicon (a-Si) thin-film technologies (Granata et al., 2014, Gerold and Antrekowitsch, 2024).

What is PV recycling & how does it work?

Shredding and sorting processes dominate today's PV recycling. As such, current processes lead to a large waste of the most valuable materials. For example, the metallic components from crystalline silicon (c-Si) panels like silver, copper, and silicon make up less than 6 wt% of the PV panel but more than 50% of the monetary value .
