Design and Optimization of a Monoaxial Tracking System for Photovoltaic Modules

Abstract EN

This paper presents researches on increasing the energetic efficiency of a photovoltaic (PV) string by designing and optimizing a tracking mechanism that simultaneously changes the daily position of the modules using a single driving source (there are modules with individual supports).

The motion is transmitted from the driving source, which is a linear actuator, with a parallelogram mechanism.

The main task in optimizing the tracking system is to maximize the energetic gain by increasing the solar input and minimizing the energy demand for tracking.

The study is performed by developing the virtual prototype of the tracking system, which integrates the mechanical device and the control system, in mechatronic concept.

Virtual prototyping software solutions (ADAMS, EASY5, and MAT) are used in this study.
