A model for predicting photovoltaic module performances

Abstract

The present paper deals with the development of a simulation model for predicting the performances of a solar photovoltaic (PV) system operating under current meteorological conditions at the site location. The proposed model is based on the cell equivalent circuit including a photocurrent source, a diode, a series and shunt resistances. Mathematical expressions developed for modeling the PV generator performances are based on current-voltage characteristic of the considered modules. The developed model allows the prediction of PV cell (module) behavior under different physical and environmental parameters. The model can be extended to extract physical parameters for a given solar PV module as a function of temperature and solar irradiation. A typical 260 W solar panel developed by LG Company was used for model evaluation using Newton-Raphson approach under MATLAB environment in order to analyze its behavior under actual operating conditions. Comparison of our results with data taken from the manufacturer’s datasheet shows good agreement and confirms the validity of our model. Hence, the proposed approach can be an alternative to extract different parameters of any PV module to study and predict its performances.

Design and implementation of an I-V curvetracer dedicated to characterize PV panels

“…The solar cell is a nonlinear device [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and can be represented as a current source model, as shown in Figure 1. In our case, a photovoltaic panel is constituted of 36 solar polycrystalline cells in series (Kyocera LA 361 K51) tilted at 35° angle facing south.…”

“…PV panel is characterized by its current-voltage (I-V) curve. Different models of solar cells were presented in literature [3][4][5][6][7][8][9][10]. The relationship of current -voltage (I-V) for a photovoltaic panel is [11,12]:…”

“…The photovoltaic panel characteristics, like any other semiconductor component is affected by temperature change. I-V obtained characteristics are shown respectively on Figure 3[3][4][5][6][7][8][9][10].…”

Recent advances in passive cooling methods for photovoltaic performance enhancement

“…Based on the temperature dependence of the opencircuit voltage, a reduction in the power conversion efficiency by 0.2-0.5% is observed with an increment of 1 °C [37]. The increase in module temperature causes a linear reduction of the output power [43][44][45]. This value denoted as a temperature coefficient and can usually be found in the manufacturer datasheet.…”

Solar Cell Parameters Extraction Methods: A Bibliometric Analysis Review

“…Accurate parameter extraction of photovoltaic models is considered a critical issue for optimization, simulation, and evaluation of PV energy systems. The authors in [3] have indicated that solar PV modules show a non-linear I-V characteristic with several parameters that need adjustment during experimental data analysis of practical modules. Although the values of some of the parameters are provided in the manufacturer's datasheet, the values of unknown parameters, such as shunt resistance, series resistance, the diode ideality factor, photo generated current and diode saturation current, are not provided [4].…”
