This paper presents theoretical and experimental researches concerning of application for a mathematical model for a photovoltaic panel with 36 Si cells in a serial circuit of Siemens SM55 PV panel type. Thus, the experimental I‐V characteristics for the five different illuminations at constant temperature are performed by the producer. A simple mathematical model is drawn from the equivalent electrical circuit with a single diode assuming the shunt resistance as infinite. A formula for the diode ideality factor is derived in this case. This model allow us to determine the optimally working point for a typically cell and for a panel made by association of cells for different insolations. The results which we have obtained yield to a numerically simulation of photovoltaic panels made by one type cells in different naturally insolation conditions.
