Estudio de un sistema solar fotovoltaico híbrido para disminuir el consumo eléctrico del campus Universidad Estatal Península de Santa Elena.

Abstract

This research examines the implementation of a hybrid solar photovoltaic system designer to reduce grid supplied electricity consumption at the main campus of the Universidad Estatal Peninsula de Santa Elena. The study addresses the need to lower energy cost, harness available solar recourses, and improve supply continuity for academic, administrative, and scientific activities. A quantitative, descriptive methodology is employed detailing data collection and design stages while accounting for infrastructure limitations alongside a non-experimental design that considers technical requirements, meteorological variables, and budget constraints. The proposal presents a 499.5 Kwp design comprising 900 monocrystalline modules (555 Wp each), organized into 50 strings of 18 modules connected to five 100 kW inverters. The photovoltaic system occupies an area of 2,902 m², operates based on 5.20 peak sun hours, generates an annual output of 758 MWh with a performance ratio of 0.80, and covers 42% of the university campus's estimated consumption. It generates a peak power of 570 kWp during August benefiting the client and includes a battery backup system to meet critical load demands. The project requires an investment of USD 525,905, with a payback period of 7.3 years. Financial analysis yields a Net Present Value (NPV) of USD 164,619.36, indicating that the system is economically viable and self-sustaining; energy savings are achieved through grid injection, securing the technical benefit of credits for surplus energy fed back into the electrical grid.
