One of the global trends in the energy sector is the inclusion of renewable sources in the grid. This need allows the reduction of greenhouse gases produced by the energetic industry, particularly with the use of fossil fuels and their effects on global warming. Therefore, these implementations need to cover the minimum requirements as balanced energy price, power demand, and a higher ROI, among others, to be reliable and compete with traditional sources. This paper presents a novel approach for sizing a hybrid renewable energy system, using data-driven decisions to meet the demand of a population in Barranquilla city. This method reduces oversizing by optimizing the number of components and increases the whole architecture's energy efficiency by managing the excess or the lack of energy through storage and backup systems.
