Um modelo dinâmico para estimação de fim de vida de painéis fotovoltaicos

Abstract

As the installation of photovoltaic systems grows to promote a path of sustainable energy generation, the disposal of end-of-life solar panels becomes a growing concern, but also an opportunity.This article investigates the future amount of end-of-life solar panels that could be improperly disposed of in municipal solid waste landfills and that could be recycled to the five most representative countries in accumulated photovoltaic capacity in the world (Germany, China, United States, Japan and India), through a Systems Dynamics model.The results indicate that there may be significant quantities of the main materials that make up a photovoltaic solar panel and that can be reused in the economy.The findings help to improve the understanding of the possible risk of unrestrained incentive to photovoltaic technology without the proper monitoring of strategies for proper treatment of this equipment when it is at the end of its life.
