As shown in the table, the values of the parameters for PV module are in close agreement with the solutions given in [1] and those determined by the models proposed in [4,[6][7][8]26]. It is clear that the proposed model allows getting more realistic results without any prior knowledge except technical data.…”

“…The numerical solutions are found for varying initial conditions and the results obtained for the BP-MSX120 PV module are listed in Table 2. The results obtained by using the model developed in [1] and [4,[6][7][8]26] are also presented in the table for comparison purposes. In this context, first of all, it should be noted that the initial conditions do not have an effect on the parameter values as one expects.…”

“…In other words, realistic results can only be obtained as the initial conditions converge to the actual values. The model in [26] also requires a powerful tool/software for the iterative solution of its nonlinear equations. In this study, Isqnonlin command based solution technique in MATLAB program is used and the objective function is chosen as given in [26].…”

“…The proposed model has been evaluated on the experimental data and the results obtained have been found to be more reliable as compared with the single diode R s -model. In addition, parameter estimation by using different approaches such as multiple optimization-based method [21], search algorithm based on the reduced form of the equations set [22], hybrid form of the Nelder-Mead and modified PSO algorithm [23], partly search-based method using diode ideality factor ( a) for the single-diode model [24] and series resistance ( R s ) for the double-diode model [25] as an independent variable, tool/software solution-based method [26] are also available in the literature. In [21], the authors proposed an algorithm based on the hybrid GA-PSO to extract the parameters of the single-diode model for PV modules, and hybrid approach was shown to be more advantageous than the method based on the GA. Bencherif and Benouaz reduced the number of parameters to be calculated only to two and reached a solution using the graphical method based on the search algorithm [22].…”

“…In this method, the procedure is reiterated until the selected value of R s coincides closely with its calculated value. In [26], the authors created five basic nonlinear equations from the equivalent circuit and solved by using a solution technique of MATLAB for one practical PV module. The reliability of the model was validated on an experimental system and the results were also compared with those obtained by two different methods available in the literature.…”

Solar energy has become a popular renewable energy source, leading to wide use of photovoltaic (PV) cells/modules in energy production. For this reason, realistic modeling of PVs and determining the equivalent circuit parameters is of great importance in terms of planning and operation. Hence, in this study, an analytical model for identifying the single-diode equivalent circuit parameters; series resistance (Rs), shunt resistance (Rp), diode ideality factor (a), diode reverse-saturation current (Io), and photon current (Ipv) for PV cells/modules is developed without neglecting any term. In order to test the accuracy of the model, a number of PV modules from different manufacturers are taken into account and the results are compared with those obtained by using such analytical models given in the literature. Current-voltage (I-V) characteristics of the PV modules, which are studied here, are also simulated by comparing with the experimental I-V curves provided by the manufacturers. Results show that the values of the parameters obtained for the PV modules are consistent with those extracted by using other analytical models. In addition, I-V curves created by using the obtained parameters are in full agreement with the experimental data. The curves also show a high degree of compatibility with the ones created by using the optimal parameters of the two-diode models given in the literature. Moreover, the proposed model provides a great advantage in estimating equivalent circuit parameters in terms of ease of use, requirements for input data, dependency on initial conditions as well as considering the parameters which are neglected in such methods given in the literature.

Finding accurate mathematical model of electrical equivalent circuit of solar photovoltaic (PV) cell is crucial to achieve and improve maximum power point, simulation design and efficiency computations for solar energy system. Due to the nonlinearity of the characteristic of solar PV cell, optimization methods are the best for estimating the electrical model parameters which lead to accurate estimating I-V curve. In this paper, camel behavior search algorithm is proposed as a new method for estimating the five different parameters for single diode model of PV solar module. This is tested on multicrystalline KC 200GT PV module. A measurement data of the module is used to verify and test the consistency of accurately estimating the set of parameters that govern the characteristics I-V relationship of solar cell. The simulation results show that the current-voltage characteristic and power-voltage curve obtained are matching to the measured experimental data set. For performance evaluation, the proposed method is simple, fast in convergence response and has an acceptable accuracy in obtaining the five estimated parameters.

With the global increase of photovoltaic (PV) modules deployment in recent years, the need to explore and realize their reported failure mechanisms has become crucial. Despite PV modules being considered reliable devices, failures and extreme degradations often occur. Some degradations and failures can be minor and cause no critical harm if within the expected range. Others, may start mildly and then deteriorate faster to become catastrophic, especially in harsh environments. This paper conducts a state-of-the-art literature review to scan PV failures, types, and their root cause based on PV’s constructed components (from protective glass to junction-box). It outlines the hazardous consequences beyond PV module failures, describing what harm they can bring to the PV system. As we delve into the literature, it becomes clear that every component is vulnerable to certain types of failures; some can deteriorate within themselves, and others infect further PV components resulting in emerging more severe failures. In the end, the review briefly summarises PV failure detection techniques, emphasising electrical characterization techniques, and disclosing the need to engage more electrical parameters. Most importantly, this review can prepare the stage for the PV research community to identify the most prevalent degradation processes. This, in turn, encourages researchers to investigate them throughout modelling and experimental studies to forecast them at the early onset in order to protect the PV systems from hazardous malfunctions.
