Abstract: Solar Energy is a clean and boundless energy source and the worldwide solar market demand is increasing for industrial and domestic purposes. The purpose of this paper is to show the comparison of Stochastic Method(Genetic Algorithm) over derivative methods. A mathematical development [3] is provided for the extraction of Solar Panel equivalent circuit parameters from datasheet values. The analytical approach is selected for the mathematical development as the initial-point vital for proper evaluation of the Parameters of the double diode Model of PV cells. And thus using Evolutionary technique to extract the values of the parameters, a valid comparison has been presented between the numerical approaches and the Evolutionary Algorithms.

TL;DR: In this paper, a synergetic control theory approach is proposed to extract the parameters of photovoltaic modules, which relies on a first analytical calculation step followed by a numerical calculation step.
Abstract: We present a new approach to extract the parameters of photovoltaic modules. This method, called the synergetic control theory approach, relies on a first analytical calculation step followed by a numerical calculation step, achieving efficient extraction of the parameters of the one-diode model, in particular the series resistance Rs. The method is based on the transformation of a nonlinear equation to a differential equation, whose numerical solution provides the values of the desired parameters simply by replacement in the previously found literal equations. To evaluate the efficiency of the method, tests were carried out on three chosen types of photovoltaic module technology, Kyocera KC200GT (polycrystalline), Shell SQ160 PC (monocrystalline), and Shell ST40 (thin film). To validate the proposed model, simulations were carried out at several temperatures and irradiation conditions.

Abstract: To be able to develop a complete solar photovoltaic power electronic conversion system in simulation, it is necessary to define a circuit-based simulation model for a PV cell in order to allow the interaction between a proposed power converter (with its associated control arrangement) and the PV array to be studied. To do this, it is necessary to approach the modelling process from the perspective of power electronics; that is to define the desired overall model in terms of the manner in which the electrical behaviour of the cell changes with respect to the environmental parameters of temperature and irradiance. The authors cover the development of a general model which can be implemented on simulation platforms such as PSPICE or SABER and is designed to be of use to power electronics specialists. The model accepts irradiance and temperature as variable parameters and outputs the I/V characteristic for that particular cell for the above conditions.

TL;DR: A PV panel model is built and tested, which is able to predict the panel behavior in different temperature and irradiance conditions, based on the single-diode five-parameters model.
Abstract: This work presents the construction of a model for a PV panel using the single-diode five-parameters model, based exclusively on data-sheet parameters. The model takes into account the series and parallel (shunt) resistance of the panel. The equivalent circuit and the basic equations of the PV cell/panel in Standard Test Conditions (STC)1 are shown, as well as the parameters extraction from the data-sheet values. The temperature dependence of the cell dark saturation current is expressed with an alternative formula, which gives better correlation with the datasheet values of the power temperature dependence. Based on these equations, a PV panel model, which is able to predict the panel behavior in different temperature and irradiance conditions, is built and tested.
