Estudo da viabilidade econômica na instalação de energia solar fotovoltaica em uma residência na cidade de Aragarças-GO

Abstract

In the midst of rain and rising rates with the electricity supply service, think about using the right energy, always focusing on the local environment. Thus, this work presents a study on the environmental and economic alternatives for the installation of a solar energy generation system through photovoltaic panels at a residence in the municipality of Aragarças, in the state of Goiás, with an average consumption of 323.5 kWh / month. The photovoltaic generation system was budgeted through the electronic simulator of the portal, at R $ 10,841.00 (with all the equipment set up and running) with a total of R $ 6,000.00 correspondence on the maintenance of the equipment. For the economic case, the results are positive and satisfactory, with a positive return in its fifth year of use, demonstrating a short-term payment system. The project became feasible by reaching values stipulated as NPV (Net Present Value) greater than zero and an IRR (Internal Rate of Return) accumulated over the attractiveness rate of the project. Therefore, in the class in question the customer obtained a rate of twenty-five years of product life a cash of R $ 67,010.20, having a satisfactory economic viability for the customer, since the same was done with the comparative rates of yield of the product with a financial rate of financing, being a rate of yield of the system greater than the attractiveness.
