The interest in delving into this subject is due to the progress in ecotourism that has been identified in the department of Cundinamarca in recent times, the limited offer of theme parks in the area, restricted access to conventional electricity, its high costs and difficult maintenance. Varsana, defined and registered as a theme park in the National Tourism Registry, will be the settlement that will benefit from the implementation of this solar energy system. To achieve the stated objective, what was established by the UNIDO methodology was achieved in its support studies: sectoral, market, technical, organizational, environmental, legal, financial and risk. It was necessary to relate findings from the tourism and renewable energy sectors to carry out a more precise analysis of the type of service offered, since Varsana provides accommodation services and unconventional experiences. In this way, it will be reduced that the Varsana project with Solar Energy is viable in the studies developed and optimal to solve the study situation.Ítem Comparison of TiO2 targets manufactured by APS and sintering processes for PAPVD coatings suitable in technological and medical applications(ASM International, 2018-01-01) Jaramillo Raquejo D.; Palacio C.C.; Ageorges H.; Jaramillo Raquejo D.; Palacio C.C.; Ageorges H.; Universidad EAFIT. Departamento de Ciencias; Electromagnetismo Aplicado (Gema)In surface science of functional oxides, Titanium dioxide (TiO2) is one of the most investigated crystalline systems either in rutile or anatase phases. Rutile phase is widely used in microelectronic, tribological applications and in the conversion of solar energy. Anatase phase is used in self-cleaning, antifogging, photo-catalytic and biomedical technologies. This work focuses on studying the required process conditions to obtain TiO2 targets by APS onto metallic substrates using commercial TiO2 powders (Oerlikon Metco in Switzerland) with suitable physical and chemical properties for technological and medical applications as PAPVD coatings. APS targets were compared to sintered ones. The raw powders were characterized by laser diffraction, SEM, XRF and XRD while the characteristics of the APS-deposited targets as well as the sintered ones were determined by SEM and XRD to identify the constituent phases. This work allowed confirming the advantages and limitations of both processes in terms of grain size, chemical composition, microstructural homogeneity and density in order to choose the best option to manufacture targets for PAPVD coatings for technological and medical applications. © 2018 ASM International® All rights reserved.Ítem “Con luz propia”.

Besides, worldwide competitions allow the spreading of such ideas where the best and experienced teams bet on innovation and leading edge technologies, in order to develop more efficient vehicles. In these vehicles, some aspects generally make the difference such as aerodynamics, shape, weight, wheels and the main solar panels. Therefore, seeking to innovate in a competitive advantage, the first Colombian solar vehicle "Primavera", competitor at the World Solar Challenge (WSC)-2013, has implemented the usage of a Concentrating Photovoltaic (CPV) system as a complementary solar energy module to the common silicon photovoltaic panel. By harvesting sunlight with concentrating optical devices, CPVs are capable of maximizing the allowable photovoltaic area. However, the entire CPV system weight must be less harmful than the benefit of the extra electric energy generated, which in adjunct with added manufacture and design complexity, has intervened in the fact that CPVs had never been implemented in a solar car in such a scale as the one described in this work. Design considerations, the system development process and implementation are presented in this document considering both the restrictions of the context and the interaction of the CPV system with the solar car setup. The measured data evidences the advantage of using this complementary system during the competition and the potential this technology has for further developments. © 2014 SPIE.Ítem Diseño de un sistema prototipo de conversión de energía solar en potencia mecánica compuesto por un concentrador solar y un motor Stirling(Universidad EAFIT, 2010) García Campuzano, José Luis;

The type of research chosen for developing this work, due to its scope and how the information was treated, is descriptive and mixed, respectively, since it contains quantitative research of an economic and financial nature, and qualitative research to describe and interpret the demand and supply of the market business, customer segmentation and the profiles of the distinct positions that the company needs The main finding of this research is that the profitability of the project has been significantly affected by the current economic situation at national and international level due to the pandemic caused by COVID-19. This is because most of the equipment for a solar energy project must be imported, and the devaluation of the Colombian peso against the dollar has carried to the costs of raw materials and maritime transport had considerably increased during the last two years. Finally, the result of this work provided enough reliable information for the partners to decide to continue with the next stage of the project, the execution, and invest the resources that the company requires.Ítem Impacto en la rentabilidad para las urbanizaciones residenciales de Medellín : Sistema fotovoltaico on-grid(Universidad EAFIT, 2024) Núñez Cadavid, Diego Fernando; Jaramillo Villa, Isabel Cristina; Giraldo Prieto, César AugustoÍtem Optimization of solar-driven photo-electro-Fenton process for the treatment of textile industrial wastewater(Elsevier Ltd, 2018-06-02) Gil, Edison Hernán; Gil, Edison Hernán; Universidad EAFIT. Departamento de Ingeniería de Procesos; Procesos Ambientales (GIPAB)This work deals with the evaluation of a solar-driven Photo Electro-Fenton (SPEF) process as an alternative for the effective degradation of an industrial textile wastewater sample. Experiments were carried out in a laboratory scale batch cell reactor, using boron-doped diamond (anode) and titanium (cathode) electrodes in monopolar configuration. The effect of the main operational parameters (pH, current density (j), conductivity (o), Fe2+ concentration and anode area to effluent volume ((A/V) ratio) on the COD removal and energy consumption were studied using a Box-Behnken experimental design. The SPEF process was optimized using the Response Surface Methodology. At optimum operational conditions (pH = 4, j = 40 mA/cm2, o = 5768 µS/cm and Fe2+ = 0.3 mM), the solar-driven process achieved total discoloration, COD reduction of 83% and TOC mineralization of 70%, after 15 min of electrolysis. The process yielded a highly oxidized (AOS = 2.24) and biocompatible (BOD5/COD > 0.4) effluent. Additionally, the most suitable effective surface area of the electrodes (A/V ratio) was determined (3.75 m-1). The analysis of operational costs was also performed. The SPEF process demonstrated to be an efficient alternative for the treatment of industrial wastewater effluent, allowing to achieve Colombian permissible discharge limits. © 2018 Elsevier LtdÍtem Optimization of solar-driven photo-electro-Fenton process for the treatment of textile industrial wastewater(Elsevier Ltd, 2018-06-02) Gil, Edison Hernán; Universidad EAFIT.

With data inputs such as vehicle geometry and its relative position towards the route, the tool was used to evaluate different possible configurations of solar panel module distribution and select the ones that are more convenient to the given scenario. Therefore, this analysis allows improving the solar panel design by considering important variables that were often overlookedÍtem Process of component integration for concentrating photovoltaic systems(Universidad EAFIT, 2017) González Correa, David Esteban; Osorio Gómez, GilbertoÍtem Solar beam radiation modeling for design and simulation of V-Trough photovoltaic applications(Universidad EAFIT, 2017) Arias Rosales, Andrés; Mejía-Gutiérrez, RicardoPhotovoltaic V-Troughs use simple and low-cost non-imaging optics, namely flat mirrors, to increase the solar harvesting area by concentrating the solar rays towards the photovoltaic surface -- Combined with stepped manual tracking, these devices can boost the performance of regular solar cells for residential and personalized scenarios in developing countries -- The geometrical set-up of a V-Trough, related to its length and angular parameters, conditions the optical phenomena that occur as the solar beam radiation dynamically interacts with the surfaces of the device -- These phenomena, such as shadows and consecutive reflections, determine the solar radiation that is effectively concentrated towards the photovoltaic area -- To support the design and simulation of such devices, this research project proposes a theoretical model of their effective concentration, seeking a high flexibility in the geometrical inputs, a detailed output of the optical phenomena involved and a low computational demand -- The model is based on the geometrical optics of beam solar radiation and it was experimentally validated in a statistical comparison against experimental measurements performed in a laser testing platform -- Based on the model, several design performance indicators were established: i) Ce (the average effective concentration); ii) Cost (the cost of materials); iii) Tsp (the space required) -- Moreover, from the integration of these indicators in proportional comparisons, three multi-objective indices were proposed: a) ICOE (Ce versus Cost); b) MICOE (Ce versus Cost and Ce versus Tsp combined); c) MDICOE (the same comparison as the previous one but also including the discretization effects related to the solar cells) – As tools for supporting the V-Trough set-up definition process, an interactive software and a series of genetic algorithms were developed based on these indicators and indices and the modeling framework developed -- The proposed software, named “VTDesign”, allows a V-Trough designer to iterate and compare diverse design alternatives in real-time by means of a visualization of the optical performance, representations of the geometrical set-ups and a cost-effectiveness analysis -- Among the genetic algorithms studied, a new genetic algorithm, named “GA-WA” (Genetic Algorithm - Weibull Arias), was proposed -- This tool uses heuristic processes, based on biomimicry and Weibull probability distributions, in order to optimize the indicators and indices as fitness/objective functions -- The intuition and the more holistic exploration of a trained engineer with VTDesign can be complemented with the broader and less biased evolutionary optimization of GAWA -- In a design case study, both VTDesign and GA-WA were implemented and found to be effective in the indices improvement, as well as efficient and flexible tools in the problem of defining the set-up of a solar V-Trough in a given personalized scenario
