Diseño de una solución energética sostenible basada en energía solar para granjas de crianza y reproducción porcina y avícola de la empresa Agripornam S.A.S.

Abstract

This thesis presents a sustainable energy solution using a hybrid photovoltaic system for Hacienda Miguel Alfredo, part of the company Agripornam S.A.S., located in Limoncito, Chanduy, Santa Elena. The main goal is to provide efficient electric power to three areas: the pig farm, the chicken farm, and the house, while reducing the use of electricity from the public grid. A study was made to know how much energy is needed. The result was 1,333.20 kWh per month, or 15,998.04 kWh per year. With this information, the system was designed using 23 monocrystalline solar panels of 550 Wp each one, giving a total power of 13.15 kWp. The system will work with an efficiency of 82% and is expected to produce 1,400.70 kWh every month. This number is a bit more than needed, allowing extra energy for battery charging, seasonal changes, and possible connection to the public grid. The system also includes hybrid inverters and a backup battery bank with 34.56 kWh capacity, enough to support four hours of critical loads for each area. The economic study presented a Net Present Value (NPV) of USD 5,471.10 and a Risk-Adjusted Present Value (RAPV) of USD 5,070.00, considering difficult situations like equipment failure, higher maintenance costs, or changes in national energy rules. As a result, it is concluded that the design system is technically and economically viable. It is also a sustainable alternative that brings environmental, social, and technical benefits to the rural area of Ecuador.
