Abstract

The identification of values of solar cell parameters is of great interest for evaluating solar cell performances. The algorithm of an artificial bee colony was used to extract model parameters of solar cells from current-voltage characteristics. Firstly, the best-so-for mechanism was introduced to the original artificial bee colony. Then, a method was proposed to identify parameters for a single diode model and double diode model using this improved artificial bee colony. Experimental results clearly demonstrate the effectiveness of the proposed method and its superior performance compared to other competing methods.

Highlights

Solar energy is one of the most promising renewable sources that are currently being used worldwide to contribute to meeting rising demands of electric power
We considered the problem of parameter identification as an optimization problem where the parameter set is sought that produces the best approximation to the I-V measurements obtained by the true solar cell
The experiment presents the results of five different algorithms when they are employed to identify the cell parameters considering the single and double diode models

Summary

Introduction

Solar energy is one of the most promising renewable sources that are currently being used worldwide to contribute to meeting rising demands of electric power. Photovoltaic (PV) is capable of Energies 2015, 8 directly converting solar energy to electricity in a quiet environment without polluting the atmosphere. It has been reported that PV is the fastest growing power-generation technology in the world, with an annual average increase of 55% between 2008 and 2014 [1]. PV systems comprise of different parts centered around a solar panel that typically has arrays of interconnected solar cells. The solar cell converts the energy of photons coming from the sunlight directly into electrical energy on the basis of photovoltaic effect. Formulating an equation that describes the performance of photovoltaic cells under illumination or in dark conditions, one from which the cells’ physical parameters can be restored, is of great value in the field of photovoltaic engineering
