A record number of photovoltaic (PV) systems have been installed around the globe as a result of the shift towards renewable energy sources, especially solar electricity. But the problem of how to sustainably handle solar panels at the end of their lifecycle will inevitably arise with this increase. Using empirical data to provide light on important trends and consequences, this paper explores sustainable alternatives of recycling solar panel materials within the framework of a circular economy. The majority of solar panels are made of silicon, which accounts for 60% of their composition. Aluminum makes up 10%, glass is 20%, copper is 5%, plastic is 3%, and other materials make up 2%. The need for efficient waste management solutions became acute as yearly garbage output climbed from 1,000 tons to 1,250 tons during a five-year period. As far as recycling efficiency rates go, silicon was at 95%, then copper at 85%, glass at 90%, aluminum at 80%, plastics at 70%, and other materials at 60%. Plastics produced 700 tons, silicon 950 tons, aluminum 800 tons, copper 850 tons, glass 900 tons, and other materials 600 tons, all thanks to recycling efforts that overcame obstacles. Based on these results, it's clear that the solar energy industry needs more efficient use of resources and better recycling procedures. Solar energy may be ensured to remain a clean and sustainable source of energy for the long term by using technical advancements, regulatory assistance, and stakeholder engagement to speed the transition towards a circular economy model for solar panel materials.
