PV modules with longer lifetimes could slash demand for materials, says NREL

The US National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritized over closed-loop recycling to reduce demand for new materials.NREL has evaluated the trade-offs between extending PV module lifetimes or ramping up closed-loop recycling for solar panels with shorter lifetimes. It presented its findings in "Circular Economy Priorities for Photovoltaics in the Energy Transition," which was recently published in PLOS One. Using the United States as a case study, a group of researchers analyzed 336 scenarios using the in-house PV Circular ...
