Sine-cosine algorithm for parameters’ estimation in solar cells using datasheet information

Abstract

This paper explores the problem of optimal calculation of electrical parameters in solar cells using three well-known operative points provided by manufacturers considering a single-diode model. These are open circuit, short circuit, and maximum power point; with these points is formulated a nonlinear non-convex optimization problem that deals with the minimization of mean square errors associated with variables evaluated at these points, i.e., open-circuit voltage, short circuit current, and current in the maximum power point, respectively. A sine-cosine algorithm is addressed in this research to solve the resulting optimization problem. Numerical results provided by the sine-cosine algorithm show objective functions lower than 1 × 10 ⁻¹², which confirms the efficiency and robustness of the proposed approach. All the numerical validations are conducted via MATLAB software.
