“…The total number of PV cells connected in parallel is equal to Np. Thus, the number of PV cells in a PV module is given by: If all the PV cells in a PV module are homogenous and are receiving an identical solar irradiance, it can be modeled in Figure 3 [25]. The total current generated from the PV module with Ns number of PV cells in series and Np number of PV cells in parallel can be modeled by using Eq.…”

A Photovoltaic (PV) cell is a device that converts sunlight or incident light into direct current (DC) based electricity. Among other forms of renewable energy, PV-based power sources are considered a cleaner form of energy generation. Due to lower prices and increased efficiency, they have become much more popular than any other renewable energy source. In a PV module, PV cells are connected in a series and parallel configuration, depending on the voltage and current rating, respectively. Hence, PV modules tend to have a fixed topology. However, in the case of partial shading, mismatching or failure of a single PV cell can lead to many anomalies in a PV module’s functioning. If proper attention is not given, it can lead to the forward biasing of healthy PV cells in the module, causing them to consume the electricity instead of producing it, hence reducing the PV module’s overall efficiency. Hence, to further the PV module research, it is essential to have an approximate way to model them. Doing so allows for understanding the design’s pros and cons before deploying the PV module-based power system in the field. In the last decade, many mathematical models for PV cell simulation and modeling techniques have been proposed. The most popular among all the techniques are diode based PV modeling. In this book chapter, the author will present a double diode based PV cell modeling. Later, the PV module modeling will be presented using these techniques that incorporate mismatch, partial shading, and open/short fault. The partial shading and mismatch are reduced by incorporating a bypass diode along with a group of four PV cells. The mathematical model for showing the effectiveness of bypass diode with PV cells in reducing partial shading effect will also be presented. Additionally, in recent times besides fixed topology of series–parallel, Total Cross-Tied (TCT), Bridge Link (BL), and Honey-Comb (H-C) have shown a better capability in dealing with partial shading and mismatch. The book chapter will also cover PV module modeling using TCT, BL, and H-C in detail.

“…The question is if it is possible to use another nonlinear relationship to improve the convergence features. Particularly, the design of Maximum Power Point Tracking (MPPT) circuits gives rise to a critical situation [12]- [14]. It is necessary to test the tracking circuit with a solar cell model describing the physical parameters with the compatibility of an electronic circuit CAD.…”

The time to market of maximum power point tracking circuits for solar cells depends on the time of transient simulations. But, the traditional tools use a nonlinear resistor model for the solar cells. The question is if it is possible to use another nonlinear relationship to improve the convergence features. This paper presents a new method for modeling a solar cell, considering temperature and irradiation changes and an improved convergence performance. In this model, the solar cell's current-voltage (I-V) characteristics for three irradiation and two temperature conditions are required, showing a feasible procedure. The proposed model is fitted to three commercial solar cells exhibiting a maximum average error of 2.51 percent. It is tested in a transient analysis converging to the expected values in a maximum power point tracking circuit.INDEX TERMS Solar cell, solar power generation, analytical models.

“…These last years, the need of electrical energy is continuously increasing, especially the need of "green" electricity with no -or -less pollution, and the need of production in some distant places where there may not be electrical network possibilities. In this context, photovoltaic modules are a very good solution, and have been studied for a long time, with different models used for simulations: single diode [1][2][3], double diode [4], and MOSFET-based [5], with for some models, the consideration of real climate conditions adding numerous parameters. A major point of these simulations is the straightforward relation existing between the complexity of the model and the necessary computation time [1], especially when the simulation includes the converter and the charge circuitry.…”

The main objective of this paper is to verify the possibility to reduce to a simple electronic circuit with very few components the behavior simulation of an un-shaded photovoltaic (PV) module. Particularly, two models based on well-tried elementary structures, i.e., the Darlington structure in first model and the voltage regulation with programmable Zener diode in the second are analyzed. Specifications extracted from the behavior of a real I-V characteristic of a panel are considered and the principal electrical variables are deduced. The two models are expected to match with open circuit voltage, maximum power point (MPP) and short circuit current, without forgetting realistic current slopes on the both sides of MPP. The robustness is mentioned when irradiance varies and is considered as an additional fundamental property. For both models, two simulations are done to identify influence of some parameters. In the first model, a parameter allowing to adjust current slope on left side of MPP proves to be also important for the calculation of open circuit voltage. Besides this model does not authorize an entirely adjustment of I-V characteristic and MPP moves significantly away from real value when irradiance increases. On the contrary, the second model seems to have only qualities: open circuit voltage is easy to calculate, current slopes are realistic and there is perhaps a good robustness when irradiance variations are simulated by adjusting short circuit current of PV module. We have shown that these two simplified models are expected to make reliable and easier simulations of complex PV architecture integrating many different devices like PV modules or other renewable energy sources and storage capacities coupled in parallel association.
