Abstract
Optimizing the mechanical device of a mono-axial sun tracking mechanism
Highlights
In order to increase the efficiency of the solar panels, a commonly used solution consists of equipping them with tracking systems, which allow the panel/collector to follow the trajectory of the sun on the celestial vault, so as to capture a greater amount of incident solar radiation [1,2,3,4]
The study is focused on the first optimization way
The optimization of the solar panel tracking systems from the point of view of the geometrical configuration of the mechanical device is based on the following stages: parameterizing the MBS virtual model; modeling the design variables, constraints and objectives; carrying out parametric design studies to identify the main design variables; optimizing the virtual model by identifying the optimal values of the main design variables that assure, by case, the minimization or maximization of the design objective functions
Summary
In order to increase the efficiency of the solar panels (photovoltaic and solar thermal panels/collectors), a commonly used solution consists of equipping them with tracking systems ( called solar trackers), which allow the panel/collector to follow the trajectory of the sun on the celestial vault, so as to capture a greater amount of incident solar radiation [1,2,3,4]. The optimization of the dynamic behavior of the tracking systems addresses two aspects (corresponding to the two main components of the mechatronic product): the geometric optimization of the mechanical structure (device), in order to minimize the driving forces developed by the actuators for performing the required motion (tracking) laws; the optimization of the control system in order to reduce the transient period, and minimize the tracking errors.
