Construcción de un sistema de energía fotovoltaica con seguidor de luz solar para el laboratorio de tribología de la Facultad de Mecánica

Abstract

A photovoltaic energy system with a solar light tracker was designed and implemented for the Tribology Laboratory of Mechanics Faculty. It consists of four stages. The first stage began with the identification of the problem, where the need for a photovoltaic system that provides autonomy for two class hours with all the energy consumption required by the laboratory arises. In the second stage, the requirements are as follows: the elements of the photovoltaic system for the laboratory must comply, along with the preparation of an operation and maintenance manual; in the third stage, the equipment of the Autonomous Distributed Generation System (SGDA) and the Transfer System were selected Automatic (STA), which allows working manually and automatically, a commercial sunlight tracking system was chosen to maximize the capture of solar radiation and increase energy efficiency. From the tests carried out, it is determined that the system is reliable and has an autonomy of 4 hours and 20 minutes. Through tests carried out, the system can reach a maximum battery charge in 4 hours 20 minutes in the month whose solar radiation is the lowest, and it is determined that the SGDA implemented represents a 48.57% savings in relation to the acquisition of a commercial system with similar characteristics. From what was analyzed, it is concluded that the implemented system is competitive and has better characteristics compared to commercial systems. It is recommended that a load study be carried out for the implementation of an SGDA that covers the total energy demand by the laboratories of Industrial Maintenance career.
