Kinematic analysis applied to a solar tracker driven by a 4-bar mechanism

This paper presents the kinematic analysis of the eccentric crank-slider and crank-rocker mechanisms applied to control the 1-DOF in a solar tracker focused on improving the conversion of solar energy into electrical energy. The mechanisms for its construction and the kinematic equations that allow to know the state that keeps the movement in the working space of the tracker and its comparative analysis between them are presented. Finally, the construction to scale with 3D printing is shown to validate the functionality of each of the 4-bar systems.
