On-Grid photovoltaic systems in vacation homes case study Tarqui-Ecuador

Abstract

Introduction: In the context of population growth, meteorological changes and energy dependence on hydroelectric sources, Ecuador faces important challenges in terms of electricity generation and environmental sustainability. Objectives: This study focuses on the technical, economic, and environmental feasibility of incorporating On-Grid photovoltaic (PV) systems in holiday homes located in the rural parish of Tarqui. Methodology: the sizing of the PV system is based on the average electricity consumption, evaluating the required system and developing a cost-benefit study using a descriptive and quantitative approach. Electricity consumption data from the last three years have been collected and processed with tools such as MedCalc and Excel. Results: The results indicate that the installation of these systems, although technically feasible, has a payback period of approximately 18 years with an IRR of 4.44%, in addition to a significant reduction in CO₂ emissions during the useful life of the system. Conclusions: It is concluded that the implementation of On-Grid PV systems in this area, although it faces economic challenges in the short term, offers important environmental benefits, underlining the need for public policies that promote their adoption to guarantee a sustainable energy future. General Area of Study: Architecture. Specific Area of study: Construction. Type of study: Original Articles.
