Design of a photovoltaic solar system for charging mobilization electric vehicles university

Abstract

Carbon dioxide emissions generated by conventional vehicles that travel within the ESPOL Campus represent 16% of the institution's carbon footprint. This affects the health of the staff and degrades the ecosystem of the Prosperina Forest, where the campus is located. Faced with this problem, this project seeks to design a photovoltaic station to facilitate the transition to sustainable mobility, changing the conventional buses to electric and allowing the charging of electric scooters that will serve as complementary transportation within the campus. The project is limited to a pilot plan of 1 busand 100 scooters that will serve as a basis for future projects. In order to fulfill this purpose, a study of climatic parameters and estimated energy demand was carried out to verify that the ideal conditions for the project existed. Subsequently, the photovoltaic system was pre-dimensioned to obtain the required area and with this data, the infrastructure for the installation of the system was selected. Next, the photovoltaic system was designed for an installed power of 48.6 kWp, connected to the electrical grid, and the number of panels and inverters was determined. Then, this design was validated through a simulation using PVSyst software, and it was determined that the solution could supply the energetic load and that there will be a surplus production that would be injected into the grid. Finally, the project would avoid the emission of 13.88 tonCO2 per year by changing the mobility systems.
