Dimensionamento e análise de viabilidade financeira de um sistema de microgeração fotovoltaico no estado do Ceará

Abstract

The demand for electrical energy production gradually increases every year in Brazil, thus making it necessary the diversification of its national energy matrix. Brazil has geographical characteristics which are favorable to the use of renewable energy, especially solar photovoltaic energy. The access to distributed microgeneration allows the consumer to generate their own energy and be compensated by surplus production. In Brazil, this process is facilitated by an assortment of government incentives to consumers who wish to be part in this sort of generation. That said, this work proposes the dimensioning and financial analysis of a grid-connected solar photovoitaic system for a retail business localized in the municipality of Itapajé, state of Ceará. This business monthly consumes 5142kWh, having a high expense with electrical energy. The economical and financial analysis will be based on investment indicators, as the Net Present Value, Internal Rate of Return, and Minimum Acceptable Rate of Return. The financial return will be based on the Payback Period and compared to other financial investments, such as the Certificate of Bank Deposit, Fixed Income Investments, and Savings Accounts. From the assessment of such indicators, it will be shown that this project is feasible, having financial return in 9 years.
