Abstract
Energy payback time is a common metric when evaluating the feasibility of PV system installations. We survey recent published estimates of energy payback time and contrast those estimates with traditional cost analyses. We provide a critical review of the method of “energy payback time” and suggest explanations for the divergence between energy payback and more conventional measures of financial payback. We argue that energy payback time analysis undercounts the true energy costs of installed PV systems.
