A circular economy for photovoltaic (PV) systems requires changes across the whole supply chain including promoting circular design and manufacturing of high-quality systems, maximizing product lifetimes through maintenance, repair and reuse, establishing high-value recycling, and reducing landfilling.A circular economy for renewable energy equipment can create a lower-emission supply chain for materials, reduce waste, and create economic opportunities. Obsolete renewable energy (RE) equipment is expected to grow exponentially over the next 30 years.
