“…The nonlinearity in model characteristics and the nature of model parameters exhibit the difficulty in precise estimation of the parameters. Moreover, it is evident that more evolved models exhibit a large number of unknown parameters, 9 where the estimation of a large number of unknown parameters is not precisely possible through analytical approaches due to transcendent mathematical equations which are difficult to analyze under various environmental conditions. 5,9 The shortcomings of analytical methods are exercised by standard numerical methods, like Newton Raphson (NR), 3 and the Gauss-Seidel method.…”

Mathematical modeling of solar photovoltaic (PV) cell/module or array is to assess its unknown modeling parameters with the experimental current-voltage (I-V) characteristic or from the manufacturer's datasheet, where exploitation of implicit and precise solution is a stern concern among researchers for the designing of an optimized solar PV system. Hence, in this article, a robust pheromone value black widow optimization (pv-BWO) algorithm is proposed to estimate precise modeling parameters of equivalent solar PV single-diode model (SDM), double-diode model (DDM), and three-diode model (TDM). The proposed algorithm is well investigated in coordination with three case studies that hold polycrystalline and monocrystalline PV modules. The suggested technique is validated through the analysis of I-V and power-voltage (P-V) performance characteristics that are meticulously analyzed under various environmental constraints. The first two case studies are widely investigated in the literature also, whereas, to affirm the suitability of pv-BWO under real implementation the third case study is carried out in an experimental environment. Furthermore, the pv-BWO method for the aforesaid case studies are validated and compared with the experimental data along with various well-established parameter estimation techniques in literature, where the proposed method promises a more reliable, stable, and precise solution for the parameter estimation problem.

In this study, the modeling of photovoltaic panels used in the generation of electricity from solar energy, which is a widely used alternative energy source, is realized. The model of photovoltaic panel and array was obtained by using single diode modeling of photovoltaic cells forming a photovoltaic panel. Firstly, single-diode modeling of photovoltaic cell is performed. In this model, by using the number of cells used on the panel, the model of the panel and the series / parallel connection of the panels were obtained and the model of the photovoltaic array constituting the energy source in the system was obtained. In this study, photovoltaiv array that consists of six 1Soltech 1STH-215-P model panel was modeled. The model has two parallel arms with three series connected panels. The electrical working curves of the obtained model at different temperature and radiation values were obtained. It was seen that very close results were obtained with each model. The results show that the presented model can be used in preliminary studies such as energy calculation and general system simulation in photovoltaic system design.
