Variations in the production techniques have led, for example, to a progressive decrease in the PV panel metal content, which ultimately caused a reduction into the value of recovered materials. A representative example is Ag, whose content in Si panels was found to be reduced from 0.14–0.2% on 2003 to 0.07–0.16% on 2023 ( Peeters et al .
The extensive deployment of photovoltaic (PV) modules at an expeditious rate worldwide leads to a massive generation of solar waste (60–78 million tonnes by 2050). A stringent recycling effort to recover metal resources from end-of-life PVs is required for resource recovery, circular economy, and subsequent reduction of environmental impact.
Recycling PV panels through e-waste management is crucial step in minimizing the environmental impact of end-of-life PV systems such as the release of heavy metals into the environment. An increasing amount of academic research on recycling approaches to PV panels that suggests different technology and policy challenges remain.
The estimated amounts of material loss potentially caused by improper disposal of PV waste in Italy are: glass (3 million tonnes), aluminium frame (498 000 tonnes), silicon metal (162 000 tonnes), copper (27 000 tonnes), tin and zinc (5 800 tonnes each), lead (2 900 tonnes), and silver (242 tonnes).
As the photovoltaic (PV) industry continues to evolve, advancements in Metal content of waste photovoltaic panels have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Metal content of waste photovoltaic panels]
Why is the photovoltaic industry considering recycling PV modules?
The photovoltaic industry is considering options of recycling PV modules to recover metals such as Si, Ag, Cu, Al, and others used in the manufacturing of the PV cells. This is to retain its “green” image and to comply with current legislations in several countries.
Can crystalline silicon photovoltaic (PV) panels be managed beyond recycling?
This research provides a comprehensive analysis of End-of-Life (EoL) management for crystalline silicon photovoltaic (PV) panels, highlighting both challenges and opportunities. The results indicate sustainable options for managing PV panels beyond recycling.
Is PV panel recycling economically viable?
Despite the clear environmental benefits documented in various studies, the economic viability of PV panel recycling remains a significant barrier. D’Adamo et al. focuses on the uncertainty of PV recycling profitability.
What is the current treatment of waste PV panel?
(1) Current treatment of waste PV panel is mainly based to the dismantling of aluminium frame and cables, and the further undifferentiated shredding of the panel. The LCA identified some hot-spots of the recycling process.
Which metals are concentrated in waste silicon photovoltaic modules?
About 95% of the metals in waste silicon photovoltaic modules concentrate in output pans A and B (conductor and middling, respectively) combined. The studied combination of parameters have no statistical differences among each other for the separation of metals. The influence of the parameters was not significant for either silver or copper.
What materials can be recycled for photovoltaic panels?
In the case of aluminium, copper and silver, the expected recovered/recycled materials are assumed to substitute primary materials. The recovered solar glass is assumed to be down-cycled into glass for packaging; electronic-grade silicon metal used in photovoltaic panels is assumed to be recovered as MG silicon metal with lower purity.
