The effect of day-to-day correlation in solar radiation on the probability of loss-of-power in a stand-alone photovoltaic energy system

Abstract This paper extends a method previously developed by the author for evaluating the probability of loss-of-power of stand-alone photovoltaic solar energy systems. As before, the method treats the energy capture, storage and dispersement process as a random walk in the storage domain. Correlation in day-to-day levels of solar insolation is now taken into account in the derivation of an expression for the probability of depleting storage.
