Solar is an emerging sustainable technology with immense potential to contribute largest investment in Green technology applications. The photovoltaic solar energy is one of the most used and promising resources in the renewable energy domain. The photovoltaic energy conversion is performed by cells based on semiconductors such as silicon, which exploits the photovoltaic effect. The these cells operation cells is described generally by the I-V characteristic which provides the information on the intern electric transport mechanisms and the technological steps imperfections of their fabrications [1-3]. The photovoltaic (PV) systems modeling has been the subject studies many recent, especially with the extension of use PV systems in different applications. The single-diode model cell solar was first used by Shockley in 1949 [4, 5] and has since been used in many other research and applications. This equivalent circuit model is based on five main parameters to be determined. The these parameters precise determination remains a challenge for the researchers, in fact, this determination is essential for the simulation, the quality control and the photovoltaic devices implementation answering to welldefined specifications [6]. These parameters also play an important role in the manufacturing processes optimization [7].The current in the Shockley equation is an implicit function; it includes dependent and independent variables at the same time. Implicit nature presents opposites to extract these parameters. An explicit analytic expression can be obtained using Lambert W [8-16]. In order to overcome these constraints that prevent the electrical parameters extraction, a new method is presented in this work. In its first part, the parameters are calculated using the Lambert function for different estimated values of the ideality factor in the interval [1-1.5], while the second part consists in determining graphically the best estima[...]
