Evaluación comparativa de dos tecnologías fotovoltaicas para la gestión óptima de carga del edificio 11A

Abstract

CONDITIONING OF PROJECT PUBLICATION. project aligns with the institutional goals of Escuela Superior Politécnica del Litoral (ESPOL) to reduce both carbon footprint and electricity consumption through photovoltaic generation. The objective is to compare two solar technologies—monofacial and bifacial panels—implemented on building 11A, and to optimize their integration through energy simulation and load management algorithms. The hypothesis proposes that a well-designed configuration can significantly improve the return on investment. A real-time energy profile was developed using IoT sensors for irradiance, temperature, and electric consumption, followed by simulation using PVsyst and optimization via AMPL and CPLEX. Three scenarios were evaluated, with and without energy storage, considering dynamic electricity tariffs, energy arbitrage models, and subsidy conditions. Results showed that the scenario without batteries but with grid injection achieved a 7-year payback period, even without subsidies, while the battery-based scenario was not profitable within a 12-year horizon due to high capital expenditure. It is concluded that distributed generation without storage, when properly managed, is both technically and economically viable. Moreover, utilizing parking areas as solar fields transforms passive infrastructure into productive energy assets.
