Researchers have developed diverse physical, thermal, and chemical methods to recycle silicon-based PV panels, aiming to repurpose damaged panels and prioritize economic and environmental sustainability (Granata et al., 2022; Ravichandran and Ganesan, 2012).
By analysing pros and cons of three methods for solar-panel disposal (artificial disassembly, use of an organic solvent, and heat treatment), it was found that heat treatment process as the prime solution.
So far, the most common methods for recycling c-Si PV modules are based on mechanical, thermal and chemical processes. Although thin-film solar cells use far less material than c-Si cells, there are concerns about the availability and toxicity of materials such as tellurium (Te), indium (In), and cadmium (Cd), for example.
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. The review also anticipates the base of solar panel recycling recommending future directions for public policymakers.

6 FAQs about [What are the methods for cutting the 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.
Can chemical recycling be used to break down solar PV panels?
Furthermore, chemical recycling solutions are gaining traction as a promising avenue for breaking down solar PV panels into their constituent materials. Solvent-based techniques and chemical baths are used to dissolve encapsulation materials, enabling the extraction of valuable components like silicon and silver.
How are thin film solar panels treated?
While many of these methods have been the subject of laboratory-based research, there are currently only two commercially available treatments. The US-based solar manufacturer First Solar applies both mechanical and chemical treatment methods to thin film solar panels.
What are the trends in solar PV panel recycling?
In response, innovative approaches to solar PV panel recycling are rapidly evolving, driven by technological advancements and sustainability imperatives. One of the most notable trends in solar PV panel recycling involves the development of advanced mechanical separation techniques.
What is the recycling process for silicon-based PV panels?
In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).
How is photovoltaic waste treated in India?
India recycling regulations: As of now, India lacks specific rules and regulations dedicated to the management of photovoltaic (PV) panel waste, and it is currently treated under general waste regulations (Preet et al., 2023).
