This paper presents the analysis of a photovoltaic microgrid to supply general services on the South Campus of the Salesian Polytechnic University. The mathematical model employed makes it possible to estimate the power generated by the source and the costs of grid energy under real demand conditions, achieving techno-economic optimization. Using HOMER Pro software, different scenarios integrating solar generation, energy storage systems, and inverters are simulated, allowing their performance to be compared in both grid-connected and standalone modes. It was determined that the geographical location of the campus offers optimal irradiance levels of 4.03 (kWh/m²/day), which favors the system’s energy generation. The simulation results demonstrate the potential of microgrids to reduce dependence on the conventional electrical system. It was identified that the off-grid mode is more efficient, as it represents a 34.82% reduction in operating costs and a 9.92% return on investment over the next 6.94 years.
