Item Diseño e implementación de un prototipo funcional de un sistema fotovoltaico autónomo con seguidor solar para carga de celulares(2024) Hernandez Alzate, Alejandro; Chávez Espinosa, Camilo Ernesto; Góngora Santana, Guillermo Alonso; Ruiz Hidalgo, Iván DaríoThis project covers the design and implementation of an autonomous photovoltaic prototype that works as a charging station for cell phones within the Universidad Santiago de Cali, the system has a solar tracking mechanism to better capture solar radiation at different times of the day and thus improve its efficiency compared to a static photovoltaic system. This work was carried out starting with the calculation of the elements that make up the system to perform the 3D design of the solar tracker mechanism and its support structure and finally its construction. The system was successfully tested by recording data for 20 days, where it could be seen how the system with tracking achieved an average efficiency of 5% compared to a static one that obtained an average of 4%, so it was found that the system with tracking had a slight improvement, but it was considered very insignificant.Item Simulación de Sistema de bombeo fotovoltaico para Campo Alegre y Ripialito en Vichada.(Universidad Santiago de Cali, 2024) Carabalí, Juan Manuel; Medina Núñez, David; Paz Parra, AlejandroMany rural communities in Colombia rely on gasoline-powered pumps to extract water from deep wells for agriculture or daily use to a lack of electricity; this is costly and environmentally harmful. This article presents a case study of a rural community proposed to solve its dependency on fossil fuels through a photovoltaic solar pumping solution. The focus of the study is the indigenous reserve of Campo Alegre and Ripialito, located in a rural area of Colombia with limited access to electricity and basic services. The community, composed of six families and 29 inhabitants, primarily depends on agricultural and livestock activities for survival. Despite 98.6% of the country having electricity, only 14.1% of this community, negatively impacting its socioeconomic development(Cabrales & Delgado, 2019). The study involved analyzing the community's water needs and the source from which the resource is extracted to propose an environmentally sustainable solution that also addresses the water access problem. PVsyst simulation software is used to simulate the performance of the solar system and calculate the economic and environmental benefits obtained with the solution. This project aims to enhance energy independence, reduce greenhouse gas emissions, close the gap in access to basic services, and promote sustainable development in the studied community.Item Diseño de un sistema de condensación de la humedad del aire alimentado con paneles solares en la ciudad de Cali(Universidad Santiago de Cali, 2024) Ramón, Manuela Victoria; Hernández, Juan Manuel; Ruiz Hidalgo, Iván DaríoThe development of a system to condense air moisture and procure water in rural Cali areas is presented, employing compression refrigeration to serve communities lacking access to water resources. Initially, the required water amount (346 liters/day) and environmental conditions based on NASA and IDEAM data (79% relative humidity and 23.3°C) were determined. System components were selected to establish its energy demand. Subsequently, through analytical calculations and the use of PVsyst software, the photovoltaic system was calculated to achieve grid independence. Finally, a cost analysis was carried out to assess the economic feasibility of the project, indicating technical feasibility but questionable economic feasibility
