Characteristics evaluation and parameter extraction of a solar array based on experimental analysis

This paper proposes a Newton-Raphson based parameter extraction method based on experimental analysis for modeling of a PV panel. In this method, pre-knowledge of open-circuit voltage, short-circuit current, maximum power point voltage and current is not necessary. Hence, the proposed parameter extraction method and analysis described in this paper can be suitably employed to obtain the panel dynamics for a PV panel without any information of voltage, current or power rating. Together with the parameter extraction, I-V and P-V characteristics and maximum power point tracking analysis has also been conducted to the PV panel.
