Study, Comparisson and Evaluation of Model Parameters of Photovoltaic Cells
Abstract
Modeling of photovoltaic (PV) characteristic (cell/module/panel/array) needs involvement of a lot of parameters, which can be classified into the internal and external parameters. Generally, catalogue sheet of photovoltaic module (issued by manufacturer) can be used as initial information to get model parameters. Nevertheless, only the parameter related to external parameters (i.e. current and voltage) are provided by the photovoltaic producer. As informed in the most of literatures, it is known that accuracy of the photovoltaic characteristic model is not only depend on the external parameters (light generated current and reverse saturation current) but also are influenced by the internal parameters (series resistance, shunt resistance and diode quality factor), therefore the proper estimation of internal parameters are very crucial. In our paper, comparison of two techniques in order to identify of model parameters will be discussed in, referring to “state of the art” of research in PV modeling, which available in literatures.
