Abstract: Solar panels, when they reach the end of their useful life, can represent a source of hazardous waste if not properly managed. Despite the significant benefits in terms of scalability from the expansion of solar energy generation, there is a risk that these panels will become waste that is harmful to the environment. In Brazil, the installed capacity of photovoltaic energy has already reached around 23.9 gigawatts (GW) and this capacity is expected to increase even further in the coming years. In this context, the objective of this research was to address, through a literature review, circular alternatives for the environmentally appropriate disposal of waste from photovoltaic panels. The analysis revealed that, despite the various circular options explored, such as repair, resale and reuse, Brazil currently only adopts the recycling alternative at the end of the panels’ life cycle. This opens up space for future investigations aimed at improving the management of this waste, the valorization of its components, as well as the reduction of its disposal in landfills.
