Markov’s residua analysis in stochastic evaluation of the photovoltaic module state operating under random conditions

The paper includes a proposal of the method of omission of the complexity problem in evaluation of the condition of the photovoltaic module under operation. The method used in the case is the Markov’s analysis requiring no understanding of physical nature of the system. The Authors prove in their paper the Markov’s character of the time-series of the residues, that is the starting point for the stochastic evaluation of the condition of the considered module, and analyze the central moments used for purposes of the module diagnostics.
