Abstract
The paper, starting from the well-known five-parameters model, proposed a new mathematical model of a Photo-Voltaic (PV) cell which can be used also for modeling a PV module or a PV string in any environment condition. The proposed approach allows to write a new descriptive equation, whose terms are function of the information always available in the modern datasheet of the PV module's manufacturers. This implies that no pre-processing of the datasheet's parameters is needed to use the proposed model, whichever are the solar irradiance and the cell/module temperature. Moreover, this model is interpreted from a circuital point of view, providing an electrical circuit constituted by basic electrical components. Particularly, in order to take into account the variability of the environment parameters, a variable resistor and several voltage-controlled sources are used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
