Viabilidade econômica de placas fotovoltaicas em uma fazenda de camarão no Ceará

Abstract

The utilization of fossil fuel represents the largest range of the Brazilian energy matrix, with the scientific community proof of negative environmental impacts, such as increased ocean temperatures and global warming. The need for the growth of renewable energy sources is an emerging need, as example the solar energy. In Brazil, this is a source with high growth, since the country has favorable characteristics for its generation and stands out for its superior solar irradiation to other countries that already use this resource. The objective of this study was to develop an economic feasibility study of an on grid-connected photovoltaic board system, at a marine shrimp production enterprise in the interior of Ceará. The work was developed from the gathering of the solar energy project documentation, in addition to data on electricity consumption and daily solar irradiation in the Tabuleiro do Norte city, where shrimp farming is located. Calculations of the following economic feasibility indices were performed: Net Present Value (NVP), Internal Rate of Return (IRR), Payback and Equivalent Annual Value (EAV). In addition, the photovoltaic system was resized to achieve self-sufficiency. The found values for this project considering all the expenses were: NVP in R$924.933,90, IRR in 38%, EAV in R$61.608,50 and Payback in three years, five months and 27 days. The results analysis indicated that the photovoltaic system implementation showed positive financial economic viability, in addition to an excellent value for financial return and profitability.
