“…This ideal model is completed with resistors to represent the losses and sometimes with additional diodes that takes into account other phenomena [10,11]. The most popular circuit equivalent to a solar cell/panel is shown in Figure 1, it includes a current source, one diode and two resistors: one in series and one in parallel [12][13][14][15][16][17][18][19]. Each element included in the equivalent circuit implies one parameter that has to be determined (two in the case of the diode whose behavior is represented by the Shockley equation [20]).…”

“…As these conditions are not enough to determine the five parameters of the equivalent circuit, in absence of more information, some authors propose to estimate the parameter a, in order to reduce the number of parameters to four [44]. This parameter is the preferred to be estimated because its value is bound to a small range, it usually is in the bracket [1, 1.5] for a single junction solar cell [19,44,45]. Applying the four boundary conditions to the equivalent circuit Equation (1) it is possible to obtain the following equations [21,46] …”

Due to the high dependence of photovoltaic energy efficiency on environmental conditions (temperature, irradiation...), it is quite important to perform some analysis focusing on the characteristics of photovoltaic devices in order to optimize energy production, even for small-scale users. The use of equivalent circuits is the preferred option to analyze solar cells/panels performance. However, the aforementioned small-scale users rarely have the equipment or expertise to perform large testing/calculation campaigns, the only information available for them being the manufacturer datasheet. The solution to this problem is the development of new and simple methods to define equivalent circuits able to reproduce the behavior of the panel for any working condition, from a very small amount of information. In the present work a direct and completely explicit method to extract solar cell parameters from the manufacturer datasheet is presented and tested. This method is based on analytical formulation which includes the use of the Lambert W-function to turn the series resistor equation explicit. The presented method is used to analyze commercial solar panel performance (i.e., the current-voltage-I-V-curve) at different levels OPEN ACCESSEnergies 2014, 7 4099 of irradiation and temperature. The analysis performed is based only on the information included in the manufacturer's datasheet.

“…Therefore, this paper aims firstly to extract lacking parameters in the manufacturers' datasheet by using a simple tool provided by MathWorks [11] and then model the PV panel. The single-diode model is used in this work because it gives a high compromise between accuracy and simplicity [12], and several researchers have used it in their works [13,14]. In addition, this work shows the effect of parameters that may change the performance of the PV panel.…”

The first objective of this work is to determine some of the performance parameters characterizing the behavior of a particular photovoltaic (PV) panels that are not normally provided in the manufacturers' specifications. These provide the basis for developing a simple model for the electrical behavior of the PV panel. Next, using this model, the effects of varying solar irradiation, temperature, series and shunt resistances, and partial shading on the output of the PV panel are presented. In addition, the PV panel model is used to configure a large photovoltaic array. Next, a boost converter for the PV panel is designed. This converter is put between the panel and the load in order to control it by means of a maximum power point tracking (MPPT) controller. The MPPT used is based on incremental conductance (INC), and it is demonstrated here that this technique does not respond accurately when solar irradiation is increased. To investigate this, a modified incremental conductance technique is presented in this paper. It is shown that this system does respond accurately and reduces the steadystate oscillations when solar irradiation is increased. Finally, simulations of the conventional and modified algorithm are compared, and the results show that the modified algorithm provides an accurate response to a sudden increase in solar irradiation.

“…The tremendous growth of PV industry and the increased number of installed PV systems all over the world raised the need for supervision and simulation tools for PV systems. To understand the PV system in a better way, modeling the PV system in various operating and weather conditions is necessary (Soto et al 2006;Carrero et al 2007). The simulation is also useful for various purposes like: (1) to analyze and study the behavior of power converters when they are attached with the PV system (Camps et al 2015;Eccher et al 2015), (2) to simulate the behavior of maximum power point tracker (MPPT) (Bendib et al 2015;Ishaque et al 2014), and (3) to estimate the efficiency of the PV system (Khazaei et al 2015;Sivakumar et al 2015).…”

In this paper, all the models of PV cell, namely ideal single-diode model, single-diode R s model, single-diode R p model, the two-diode model, and the three-diode model, have been discussed. SPICE simulation is done to evaluate the impact of model parameters on the operation of PV cell. The effects of the parameters are discussed. The photocurrent, I L , is proportional to irradiance, and the series resistance, R s , reduces the short-circuit current and fill factor. The parallel resistance, R p , reduces the open-circuit voltage, and both the diffusion diode and recombination diode reduce the open-circuit voltage value and fill factor. Finally, it is shown that an increase in cell operating temperature reduces the open-circuit voltage and fill factor and thus degrades the performance significantly.
