Different methods of evaluating the performance of photovoltaic systems have been used to date; the main differences are in the details used in the system component descriptions and the temporal step used for the energy balance.

Abstract

Different methods of evaluating the performance of photovoltaic systems have been used to date; the main differences are in the details used in the system component descriptions and the temporal step used for the energy balance. In this paper, an approximate energy analysis model and a more complex power analysis model are analyzed and compared. By simulating the performance of several completely different photovoltaic systems, we show that the results become nearly coincident for increasing values of a parameter proportional to the storage capacity. Therefore, this parameter must be considered to decide a priori the reliability of the approximate energy analysis.
