Recently, the use of renewable energy has attracted the interest of several scientific communities due to the environmental consequences of fossil fuels. Many different technologies have been proposed for the exploitation of clean energies. One of most used is the solar cells considering their unlimited source power characteristics. The estimation of solar cell parameters represents a critical task since its efficiency directly depends on their operative values. However, the determination of such parameters presents several difficulties because of the non-linearity and the multimodal properties from the estimation process. The problem of solar cell parameter estimation has been widely faced through Evolutionary Computation (EC) techniques. Essentially, these methods have produced better results than those obtained by classical methods regarding accuracy and robustness. Each EC algorithmhas been designed to fulfill the conditions of specific problems since no one approach can optimize all problems effectively. Under such circumstances, the performance of each EC approach must be correctly assessed considering the application context. Several proposals of EC methods to estimate the parameters of solar cells have been reported in the literature. However, most of them report only a single EC technique considering a minimal number of solar cell models. In this paper, a comparative study of EC techniques used for solar cells parameter estimation is proposed. In thestudy, the most popular EC approaches currently in useare considered, evaluating their performance over the complete set of solar cell models.
