In this report we analyze drivers, barriers, and enablers to a circular economy for PV system materials in the United States. We also analyze federal, state, and local requirements that apply to the reuse, recycling, and disposal of PV modules and BOS equipment, as well as the legal liability associated with non-compliance. We then discuss state policies and initiatives in the United States that expressly address reuse, recycling, and disposal of PV system equipment. We conclude by providing case studies of U.S. business models for the repair, reuse, recycling of PV modules and BOS equipment.
