Abstract
ABSTRACTSiting for utility-scale solar photovoltaic (PV) projects is a challenge for developers. Some solar PV technologies require upward of 8 acres per megawatt (MW). Erecting solar atop closed landfills is a viable option to minimize post-closure landfill maintenance and transform those liabilities into productive, renewable energy assets for the long-term.This article examines costs and benefits of geosynthetic membranes particularly suited to host solar PV systems. Authors review examples from existing, operational projects and discuss how technologies have overcome some of the challenges with first-generation attempts to mount solar on landfills: differential settlement with traditional soil closures, delamination of solar modules, etc.
