<p>The global surge in photovoltaic (PV) panel deployment since the 2000s has contributed to advancing the renewable energy sector.

This paper addresses this imminent challenge by presenting a predictive model to estimate the volume of decommissioned PV modules from existing installations. To consider the variability associated with the operational life duration of PV panels, two different scenarios were considered: early loss and regular loss, both modelled through the Weibull function. Furthermore, the article proposes a methodology for the economic valorization of materials recovered from decommissioned PV modules, according to the different technologies employed. This approach encourages sustainable practices by assigning an economic value to recovered materials and promoting a circular economy in the renewable energy sector. The economic valuation methodology adds practicality to dismantling, emphasising responsible waste management’s potential economic benefits.
