This work aimed to analyze the economic feasibility of the implementation of a photovoltaic system connected to the electric power grid in a residence in the city of Curitiba, Paraná. Exploratory research was carried out, through bibliographic research with a descriptive and quantitative approach. Through calculations, the ideal potency of the photovoltaic system was determined and budgets were determined with specialized companies to determine the investment cost. Considering a Cost of Capital, the following methods of analysis were used: Simple Payback, Discounted Payback, Internal Rate of Return, Internal Rate of Modified Return, Net Present Value and Profitability Index. For comparison with the implementation of the system, were analyzed the investment in Savings Account, Direct Treasury, Bank Deposit Certificate, Real Estate Credit Letters and Agrarian Credit Letters, which are the main investments available in financial entities. It was concluded that the investment in the photovoltaic system only meets the method of Simple Payback with 11 years and 10 months, as for the other methods, this application did not prove profitable for the investor. The investment that brought the best return to the investor was the Bank Deposit Certificate, with a 6-year and 10-month Simple Payback, Discounted Payback of 12 years and 11 months, NAV of R $ 11,799.75, IRR of 20.53% TIRM of 17.11 and Profitability Index of 1.6896 at a cost of capital of 14.68%. |
