Evaluación técnico económica del alumbrado público fotovoltaico en la calle Elia Liut de la ciudad de Cuenca

Abstract

The present work aims to conduct a technical and economic evaluation of the photovoltaic public lighting system installed on Elia Liut Street in the city of Cuenca. The study analyzes its performance considering technical aspects such as luminous efficiency, light distribution, and lighting uniformity, as well as economic factors related to installation, operation, and maintenance costs. The investigation begins with a detailed review of international and national standards on public lighting and photovoltaic systems. Subsequently, measurements of light parameters are carried out using specialized equipment, such as a luxmeter, luminometer and spectrometer, to determine the actual lighting level provided by the system. The collected data are compared with the recommended values established by current regulations, enabling the identification of potential deficiencies and areas for improvement. Additionally, an economic analysis is conducted, including implementation costs, energy savings, and return on investment, considering the system’s lifespan. The results provide recommendations to optimize the photovoltaic lighting system’s operation, enhancing the service’s sustainability and efficiency. Finally, future research lines are proposed, such as integrating smart technologies and using complementary renewable energy sources.
