Design of a 50 kWp photovoltaic generator applied to a case study

Abstract

The design of this photovoltaic generator responds to the need of a Higher Education Institution to provide electricity without blackouts to a Faculty building of more than 1.200 people. It was necessary to determine the electricity demand priorities of the different units of the Faculty in order to design the 50 kWp solar photovoltaic generation system based on the selected methodology. Based on the knowledge of the irradiance at the site of the photovoltaic project, it was possible to determine the number of solar panels and how they should be arranged in series-parallel arrays for connection to the inverters. The designed system was successfully validated with the use of the PVsyst software. The results achieved were satisfactory, the generation system can be implemented at a reasonable cost and the Faculty can count on an uninterrupted supply of electricity during the hours in which university activities are carried out. The reality of the country makes public and private companies consider the use of photovoltaic solar energy as an alternative to compensate for the energy deficit, either as consumers or suppliers of electrical energy.
