This article reviews degradation rates of flat-plate terrestrial modules and throughout the last 40years. The target audience of these PVFSs are PV planners, installers, investors, independent experts and insurance. . As photovoltaic penetration of the power grid increases, accurate predictions of return on investment require accurate prediction of decreased power output over time. Degradation rates must be known in order to predict power delivery.
