“…Focusing on low irradiation conditions (about 100 W/m 2 ), reference [42] describes that the parallel capacitance at MPP and OC conditions could achieve a 294% and 340% value, respectively, compared to that of the SC condition. The resulting parallel capacitance is also irradiance-dependent [42,46,51,59,60]. Thus, for different voltage biases, this capacitance could decrease in the range 15% to 70% when irradiance decreases from high to low irradiation [42,60].…”

“…The most widely used method to study the PV dynamic behavior is the impedance spectroscopy [40,43,[54][55][56][57][58]. Alternative methods are based on time domain techniques [59,60]. Based on these or other methods, the AC parameters of a PV cell/module, such as capacitance and parallel and series resistance, can be accurately characterized.…”

Photovoltaic (PV) systems are subject to nearby lightning strikes that can contribute to extremely high induced overvoltage transients. Recently, the authors introduced a 3D semi-analytical method to study the electromagnetic transients caused by these strikes in a PV module. In the present paper we develop an improved model of the PV module that: (a) takes into account high-frequency effects by modelling capacitive and inductive couplings; (b) considers the electrical insulation characteristics of the module; (c) includes the connection to a DC/DC converter. The whole process involves three major steps, i.e., the magnetic-field computation, the evaluation of both common-mode- and differential-mode-induced voltages across the PV module, and the use of the calculated voltages as input to a lumped equivalent circuit of the PV module connected to the DC/DC converter. In such a framework, the influence of the PV operating condition on the resulting electrical stresses is assessed; moreover, the relevance or insignificance of some parameters, such as the module insulation or the frame material, is demonstrated. Finally, results show that the induced overvoltage are highly dependent both on the grounding of the conducting parts and on the external conditions such as lightning current waveforms and lightning channel (LC) geometry.

Summary The objective of this paper is to compare the performances of different photovoltaic (PV) array configurations (series, parallel, series‐parallel, total‐cross‐tied, bridge‐linked, and honey comb) and proposed hybrid configurations (series parallel–total cross tied, bridge linked–total cross tied, honey comb–total cross tied, and bridge linked–honey comb) under artificial and realistic partial shading conditions. The performances of all these configurations have been compared on the basis of their maximum powers, fill factors, thermal voltages, and relative power losses. Different PV array configurations have also been compared on the basis of other significant factors (faults, limitations of specific parameters of the PV system, and cost). The single‐diode model of PV module is considered in this paper for modelling of PV module. The obtained results of different PV array configurations give beneficial knowledge regarding the performances of these configurations for several shading patterns and assist to choose the most satisfactory configuration for a particular shading pattern.

“…Cells of PV are expensive, and the PV devices features are extremely reliant on ecological circumstances. As a result, to confirm the extreme using of the obtainable solar energy via a PV power scheme, it is significant to study its performance over modeling, beforehand applying it in reality [5]. The climate is permanently varying and as many researchers are hard to plan methods to improve the effectiveness of photovoltaic panel.…”

Renewable energy sources are becoming more and more popular, regarding the pollution and non-sustainability of common energy sources. Photovoltaic is the most direct way to convert solar radiation into electricity using the photovoltaic effect. This technology generates direct current (DC) electrical power from semiconductors when they are illuminated by photons. This paper presents a mathematical model in CFD that simulates the thermal presentation of a solar thermal photovoltaic panel equipped with circler, square and elliptic pin fin cooling module. The effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature has been studied and the effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature. The results show that velocity contours for water flows in circular, elliptic and square pin fin cooling module with inlet water velocities (0.0002, 0.0004 and 0.001 m/s). It is noticed that for square pin fin, the velocity between the pins is higher than the other types of pins, which leads to more circulation of water and more cooling.
