Análisis de viabilidad técnica y económica de generación eléctrica mediante sistemas fotovoltaicos aplicado en una empresa de productos alimenticios

Abstract

The object of this study was a food products company, which is currently experiencing excessive spending in terms of paying for electricity, even taking into account the context of the energy crisis in Ecuador where there were up to fourteen hours of power outages per day, thus, the general research objective was established to determine the technical and economic feasibility of electricity generation through photovoltaic systems applied in a food products company in the city of Guayaquil to reduce energy costs. In order to fulfill the aforementioned objective, a simulation of the photovoltaic system was carried out where photovoltaic modules with a power of 150 Wp and a total of 60 modules were used, which results in a total power of 9000 Wp or 9 kWp., another important aspect was the calculation of the working voltage of the system, which depended on the number of photovoltaic modules joined in series, with a correct formula giving an operating voltage of 532.20 V by combining 30 modules in series with a main voltage of 17.74 V per module. This value is good since the inverter that was chosen has a range between 200 V and 700 V, which means that the system will be compatible with the chosen inverter without exceeding the voltage limits for its task. In conclusion to the economic viability, the analysis of the installation costs, which amount to $23,000, shows that the initial investment can be amortized in a reasonable period, with an estimated return on investment in 12 years. In addition, the benefits of solar energy generation contribute to sustainability, which represents an advantage both economically and environmentally.
