Análise da implantação de gerador a diesel e de um sistema solar fotovoltaico on-grid em aviários de frango de corte em Toledo - Paraná

Abstract

The growth in energy demand and the strong concern for sustainability generate the search for alternative sources of electricity, the main one being photovoltaic solar energy. Among the costs of broiler aviaries, electricity stands out, which represents 18% of the total, due to controlled climate control and other automated systems, so that the implementation of a photovoltaic solar system becomes a solution that must be analyzed for reduce energy costs. The diesel generator on standby is a solution to the unreliability of the utility's electricity supply, since a failure or interruption can generate losses ranging from 100 to 250 thousand reais, depending on the duration, weather, and period. of poultry fattening. Thus, this work was developed in a set of three poultry aviaries with a production of 32,000 birds per lot, located in Vila Nova, district of Toledo - Paraná. The study presents the design and economic evaluation of an on-grid photovoltaic solar generation project and the implementation of a diesel generator. The analyzed on-grid photovoltaic system project presented a discounted payback of 6 years and 9 months, NPV of 957,302.16 and IRR of 236,81%, an economic gain of 8% for the first 10 years and 26% for the last 15 years, of the revenue of the aviaries, in addition to the positive environmental impact, since it can avoid the emission of 12.757,04 kgCO2/year. The implementation of the diesel generator, in turn, analyzed in six scenarios, resulted in scenario 1 in NPV of R$ 4.604.812,56 and IRR of 333,89%; noting the financial and environmental benefits, as well as the economic viability of installing a diesel generator and a photovoltaic solar energy generation system in broiler chicken farms.
