The governing equations were obtained with the Lagrangian function and the results were found using the Runge–Kutta method for integration. These results were found using two different models. One of them considers the panel directly connected to a DC motor and the other considers a torsion spring connected to the motor shaft and the solar panel. As a result, we obtained the time series of the mathematical model proposed.369-383engNonlinear dynamicsSimplified modelSolar panelVibrationsCapítulo de livro10.1007/978-3-030-75890-5_212-s2.0-85111846763
