Diseño y construcción de un sistema de rastreo solar biaxial para generación de 600 W-h de energía eléctrica

Abstract

The energies classified as renewable have become an environmentally viable alternative to generate energy, among them solar energy stands out, which is an inexhaustible source. Currently the amount of energy that planet earth receives is approximately 4,500 times the amount of energy consumed in a day. That is why the current technical project proposes the search for a design which will allow the construction of a solar collection system using photovoltaic solar panels and a dynamic solar tracking mechanism to increase energy productivity for residential use, in order to compare it with a fixed system analyzing its profitability and technical viability within the residential urban sector of Quito. As a result of the study, it has been determined that through the use of the solar tracker, it has been possible to obtain an increase of 43.6% in energy efficiency production with the solar tracking system in the month of June in 2021 compared to the fixed solar installation during the month of May in 2021. The economic analysis shows that the breakeven point for the solar tracking system is in 17 years and the one on the fixed system in 15.4 years after its installation. The cost of the solar tracking project is $ 2,140 USD equivalent to 55% more than the fixed installation which is $ 1,185 USD. However, 20 years after installation, the user will obtain more profit from the solar tracking system than from the fixed system, with a profit of 354.45 USD and 353.86 USD respectively, making the project viable in the long term.
