چکیده :

In this paper, some novel physical constraints are proposed on parameters of the double-diode (DD) photovoltaic (PV) model with rigorous mathematical analysis. These constraints are some inequalities between seven unknown parameters of the DD circuit model. The inequalities are achieved from the datasheet information and well-known nonlinear current-voltage I-V equation of the DD PV model. This is the first study, in which a large variation of the constraints are derived. These constraints can be utilized to determine the feasible regions of the unknown parameters. Considering the proposed inequalities, each PV module has its own feasible search spaces based on its datasheet. Moreover, these inequalities are extended to real environmental condition by updating the datasheet parameters.
