AbstractThe energy needs to facilitate daily tasks, in combination with the difficulty of carrying out solutions to certain regions of the country through the National Interconnected System (SIN) makes it necessary to search for viable economic and self-sustaining supply alternatives that compensate for this shortcoming. at the national level, Non-interconnected areas (ZNI) comprise 52% of the Colombian national territory (SSPD, 2019), in addition to this a fossil fuel crisis is looming, so it is vitally important to provide energy solutions in the short and medium term over the long term. and width of the country. In Colombia since 2010, small-scale photovoltaic solutions have been implemented, but the 2015-2029 expansion plan of the UPME (UPME, 2016) contemplates the inclusion of alternative energies in the SIN, as well as incentive programs for generation of non-conventional energies such as solar, wind, biomass, among others. The incentives include tax exemptions for the basic elements of the photovoltaic system such as panels and inverters, as well as credits and programs for the acquisition of solar photovoltaic energy. In this work, the dimensioning of a photovoltaic solar system is carried out as an energy solution for multi-family homes in a non-interconnected area of Colombia, specifically in the department of Vaupés. To achieve the proposed objective, a general characterization of the area under study is carried out. In addition, the procedure to determine the type and characteristics of the components of the proposed system is detailed, reaching the number of 6 solar collectors, connected to a 3000 W hybrid inverter and a 48V 150 Ah energy storage system; in the same way, the calculations of the approximate costs of construction of the project and return on the investment of the project are made, which is estimated in approximately 1.5 years producing 3385,476 KWh per year approx; The PVGIS simulation software is used to verify the proper functioning of the designed system, and finally, with the Digsilent Power Factory software, the load flow analysis of the installation is carried out to guarantee its correct operation.
