Modeling and parameter extraction methods of PV modules — Review

The main objective of this paper is to provide the researchers and developers with a review of the characteristics of PV modules and the different possible methods of extracting parameters for modeling a PV system. Modeling a Photovoltaic (PV) module is essential for both software and hardware implementations, for operating and testing the performance of PV system. PV characteristic curve is non linear and modeling it accurately needs determining the parameters associated with the panel accurately, which are not usually provided in manufacturer data sheets. To get the I-V Curve of a PV panel in single diode model, the characteristic parameters should be extracted from the manufacture´s datasheets. This paper analyzes conventional methods and intelligent methods which are available for extraction of parameters for modeling PV modules, along with their respective advantages and limitations.
