Diseño e implementación de un sistema seguidor solar inteligente a dos ejes para optimizar la producción de energía fotovoltaica con una lente de fresnel y un sistema de limpieza robotizado a bajo costo

Abstract

Photovoltaic systems with Fresnel lenses are expensive, as well as technologically complex, due to their optical, mechanical and control components. In addition, all these systems are sensitive to operation and maintenance costs. This article proposes the use of commercial Fresnel lenses to improve the efficiency of photovoltaic modules, in conjunction with a fuzzy intelligent controlled solar tracking system with two-axis and a novel low-cost robotic cleaning system. The basic idea is that this system optimizes the production of electricity in an economically and technologically simple way. The technology of Arduino microcontrollers and fuzzy logic for control, as well as the geometry of Fresnel lenses, will be used to concentrate solar energy in a small area, not to mention that these optical devices have a low weight. The accumulated effect of energy production will be improved by a novel low cost robotic cleaning system. The alignment and perpendicularity of the impact of solar energy on photovoltaic cells must be maintained as much as possible and the performance of this system must be compared with other more expensive and technologically more complex commercial systems.
