Análisis técnico-económico de una estación de carga fotovoltaica para vehículos eléctricos en el parqueadero de la FIEC

Abstract

CONDITIONING OF PROJECT PUBLICATION. growth of the electric vehicle fleet in Ecuador demonstrates the existence of an opportunity to improve the infrastructure dedicated to these vehicles. The study evaluates technical-economic viability of a photovoltaic charging station in the FIEC car park, with the objective of offering a sustainable energy solution that promotes the transition to electromobility on campus; in response to institutional and municipal policies that promote the use of renewable energy and require the implementation of chargers in at least 1% of public car parks. The design was based on national and international standards, considering energy demand analysis, sizing of the photovoltaic system and validation of interconnection in synchronism with the medium-voltage grid using simulation tools. Longi bifacial photovoltaic modules were used in combination with Growatt inverters, generating 209,700 kWh per year, providing 49.7% of the energy consumed by BYD chargers for standard charging and BENY for fast charging, in addition to an estimated reduction of 1,313.846 tCO₂ in 25 years. The project proves to be feasible, replicable and economically profitable, with a return on investment of ten years. Finally, it demonstrates implementation contributes to campus sustainability and a possible expansion.
