Dual model representation of solar photovoltaic cell

Abstract The sustainable development of the country is dependent on the utilization of power production from renewable energy sources like solar, wind, hydro, etc. Due to availability of solar energy in most of the places, the focus of using solar energy by implementation of solar PV cells, arrays, panels are the primary strategy. Thus, the designing of solar PV cell is necessary. There are certain topologies i.e. single diode and double diode representation for solar PV cell. But designing these models individually takes utilization of time and resources when implemented in real life scenario. When coming to the performance analysis of these models individually, it is observed that the power production is not in the maximum capability throughout the year. The performance in some months is good for single diode topology whereas in other months double diode topology shows good result. So, a new model is proposed with better performance, combining these two models that will solve the above disadvantages. Further, both the time and price of production goes down as we don’t have to create both the models separately. The entire analysis is studied for an entire year for the place of New Delhi. The comparison is also done taking into consideration of two practically existing solar cells: JAP6-72- 320/4BB and Solarex: MSX60 allowing each model to work as single and double diode representation. As the production capacity of these design is not to its highest extent so, more number of cells are attached in series or parallel fashion to meet the load demand. The proposed design solves this problem and having an error within the limit of 0.31–0.41%. The mathematical modelling is shown followed by designing the model in Simulink and thereafter comparative analysis stating all the disadvantages is analyzed, followed by the solution with the best topology for power production from solar cell. This sequential designing will give clear understanding of the proposed technology.
