Abstract

Abstract This paper presents the preliminary results of an environmental evaluation carried out by the application of Life Cycle Analysis (LCA), to a new method proposed for managing the end of life of thin film photovoltaic panels that is being developed by a company leader in design and installation of photovoltaic solutions. The new method is being developed in an experimental test facility established by the company for implementing a series of mechanical and hydro mechanical treatments to thin film panels at the end of their life before the ultimate material recovery phase. The main innovation of the method consists in the elimination of the thermal treatments and the reduction of chemicals needed for recovering valuable materials, in favor of mechanical processes. The results demonstrate that the mechanical treatments used in the pre-treatment phase of the module has a positive effect in almost all the damage categories defined in the LCA and contribute significantly to the reduction of the global warming and the carbon footprint of the photovoltaic technology.
