In this paper, a new method of modeling PV modules in the Pspice simulator is proposed. This method consists in describing the behaviour of PV modules and the evolution of their I-V characteristics as a function of the temperature and the solar irradiance. The developed modelling technique is based on the internal physical parameters (photogenerated current (Iph), saturation current (Is), ideality factor (n) of the diode, series resistance (Rs) and shunt resistance (Rsh)) extracted using a high performance extraction method based on the experimental characteristics of the studied module. Experimental measurements of I-V characteristics were taken, under real operating conditions, using a high-precision I-V curve plotter. The values of these parameters are injected into the single diode model established under the Pspice simulator. This technique allows to construct with satisfactory simplicity the I-V curve of different PV module technologies under different environmental conditions. The comparison of simulation results and those obtained experimentally shows the accuracy of the used method. Furthermore, based on measured data, extracted saturation current, series resistance and ideality factor seem to be not influenced by the variation of the irradiance. Then, the comparison of the extracted parameters with those calculated by empirical laws proposed in literature, shows the reliability of these laws and this for the studied monocrystalline PV module. Moreover, it has been studied, experimentally and with empirical laws, the evolution of the efficiency and the power, of the studied PV module, as a function of the temperature. It appears that the rise of temperature from 25 ° C to 55 ° C deals with an electrical efficiency drop of about 2.2 %.

In this work, a numerical approach has been proposed to estimate the five single-diode circuit model physical parameters of photovoltaic generators from their experimental current-voltage characteristics. Linear least square method has been used to solve the system of three linear equations to express the shunt resistance, the saturation current and the photocurrent as a function of the series resistance and the ideality factor. Two key points have been used to solve the system of two nonlinear equations to extract values of series resistance and ideality factor. The advantage of the proposed method with respect of existing numerical techniques is that use only two key points of the experimental characteristic and need only two initial guesses and does not use any approximation. To evaluate the proposed method, three PV generators data have been used to compare the experimental and the theoretical curves. The application of the proposed method provides a good agreement with the experimental.

This work suggests a new method for extracting parameters from the current-voltage characteristics of photovoltaic (PV) panel to establish translational relations that allows to predict these PV parameters in other conditions of temperature and irradiation levels. This method is based on the knowledge of few selected points which are the short-circuit point, the maximum power point, and the open circuit point. These points are extracted from the current-voltage characteristics provided by the manufacturer's datasheet. Single diode model is chosen to represent the PV panel which is known as five parameters model. It includes two parasitic resistances, diode saturation current, diode ideality factor, and photo-current. The main results of simulations in Matlab environment show that the five PV parameters varies as function of irradiance and temperature. The proposed technique is compared to other published methods applied on Kyocera KC175GHT-2 PV panel. The obtained results show that the new suggested method of predicting PV parameters presents a lower statistical error whatever the weather conditions. Therefore, the new method is validated and more precise than extraction methods reported in the literature.
