The equivalent circuit of a PV cell is shown in Fig. It is obvious that the application of the ﬁnal model must correspond to the best compromise between simplicity and accuracy. However, these models are not adequate for application involving hybrid energy system since they need a flexible tuning of some parameters in the system and not easily understandable for readers to use by themselves.

The single-diode model has been derived from the well-known equivalent circuit for a single photovoltaic (PV) cell. (4). He received master degree in electrical engineering in University of Wollongong, Australia in 2012. TABLE 3 The models are formulated using Eureqa software based on thousands of training data collected from simulating the equations that represent the equivalent circuit behavior of the PV cell. Significance of Study Photovoltaic cell is formed from the simple arrangement of diodes which produces direct current (DC) due to the movement of electrons as the intensity of the sun increases. The solar module simulation procedure is shown from Fig. A step-by-step procedure for simulating PV module with subsystem blocks with user-friendly icons and dialog in the same approach with Tarak Salmi and Savita Nema is developed by Jena, Pandiarajan and Muthu et al. 2012), (Panwar and Saini 2012), (Savita Nema and Agnihotri 2010), and (Sudeepika and Khan 2014).

The proposed procedure provides an accurate, reliable and easy-to-tune model of photovoltaic array. The disadvantage of this method is that it is quite challenging or even unable to collect sufficient data if no experimental system be available so that modeling curves cannot be built and modeled. cells, especially in developing models using various softwares.

MPN assisted in designing, data collection, analysis and reviewed the manuscript and edited many times and added his inputs. Lack of presenting step-by-step simulation procedure and this causes difficulties for readers and researchers to follow and do simulation by themselves. A PV cell has a non-linear voltage- current (V-I) characteristic which can be modeled using current sources, diode(s) and resistors. Among other authors, a proposed model is based on solar cell and array’s mathematical equations and built with common blocks in Simulink environment in (Salmi et al. In these papers, only two aspects (solar irradiation and temperature) are investigated without providing step-by-step simulation procedure. The reference model is 36-series-connected-cell array so two cases are studied: two modules are connected in series and two modules are connected in parallel. cell/module used following nomenclature. In practice, PV cells are connected in series into PV module and these PV modules then are connected in series or parallel to form PV array for generating more electricity from sunlight.

Summary when Rsh varies between 1000 and 1 Ω, the current output and voltage output decreases slightly and this results in slight net reduction in power output. 2014) and (Venkateswarlu and Raju 2013), a solar cell block which has already been built in Simscape/Simulink environment is employed. 3. Similar value of power output is experienced in both cases of two modules despite different ways in module connection (parallel or series). Another method which is the combination between Matlab m-file and C-language programming is even more difficult to clarify (Gow and Manning 1999). 17. For any solar cell, the model parameters are function of the irradiance and the temperature values of the site where the panel is placed.
