Abstract: This paper presents modeling of a Photovoltaic (PV) module using Matlab/Simulink. The module consists of 36 polycrystalline silicon solar cells electrically configured as two series strings of 18 cells each. This five-step method calculates through MMPP per day, per month, or per year, the power yield by unit area, then electrical energy generated by PV panel, and its real conver… 6. This research is the first step to study a hybrid system where a PV power generation connecting to other renewable energy production sources like wind or biomass energy systems. Another method which is the combination between Matlab m-file and C-language programming is even more difficult to clarify (Gow and Manning 1999). 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. 6. a Modeled circuit for Eq. Finally, XHN decided finally the content of the research revised final manuscript. b Output P–V curve with varying temperature. Banu I-V, Istrate M (2012) Modeling and simulation of photovoltaic arrays. 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. A step-by-step procedure for simulating a PV array with Tag tools, with user-friendly icons and dialogs in Matlab/Simulink block libraries is shown. In addition, more shaded modules are higher number of power output peaks is shown. Similar value of power output is experienced in both cases of two modules despite different ways in module connection (parallel or series). It is obvious that the application of the ﬁnal model must correspond to the best compromise between simplicity and accuracy. From the work of (Ibbini et al.
