Sustainable Solar – Recycling Photovoltaic Panels for a Greener Tomorrow

The fast expansion of solar photovoltaic (PV) technology has placed it as a prominent participant in the worldwide transition towards renewable energy but the rising quantity of end-of-life (EOL) solar panels creates substantial environmental and economic issues. This review paper addresses the composition and construction of solar panels, present recycling procedures, and the accompanying social, environmental, and economic effects. This review is undertaken on the efficiency and capacity for expansion of current recycling technologies, such as mechanical, thermal, and chemical processes and Challenges such as excessive cost, environmental impacts, and logistical challenges have been noted, coupled with non-technical hurdles including gaps in rules and insufficient infrastructure for obtaining data. Potential advancements like advanced silicon recovery, supercritical water technology, and simulation modeling are considered as means to enhance material recovery and process sustainability in the future. The study underscores the significance of a circular economy, pointing out the necessity of strong global policies, extended producer responsibility (EPR) programs, and collaboration among stakeholders. This thorough assessment highlights the importance of sustainable recycling in tackling the end-of-life challenges of PV panels, which helps in creating a more environmentally friendly future.
