Abstract

This paper presents an energy performance study based on probabilistic model for the power produced by a PhotoVoltaic System (PVS). Three different PVSs configurations have been studied and compared: flat, one-axis and two axis tracking systems. In particular, the impact of a tracking system on the probability density function (PDF) of the power produced by a PVS has been evaluated through the first fourth moments (mean, variance, skewness and kurtosis) of a PDF. The simulations results have been compared with experimental data related to a 9.6 kW_p PV plant installed in ENEA research center located in Portici, Napoli (Italy).
