ECONOMIC FEASIBILITY ANALYSIS OF A RESIDENTIAL PHOTOVOLTAIC PROJECT IN THE CITY OF TAQUARITINGA/SP

Abstract

The demand for national energy diversification has been gaining notoriety and in this perspective solar energy projects have been increasing significantly. Currently, many companies operating in sales and maintenance point out that this type of investment is very advantageous and profitable. This paper addresses the economic and financial feasibility of adopting a residential solar energy project, through estimates of monthly and annual consumption and the cash flows generated when adopting a photovoltaic system. The methodology used was the bibliographic review and financial indicators NPV - Net Present Value, Payback, IRR - Internal Rate of Return, TMA - Minimum Rate of Attractiveness. When mapping the five-room appliances, an expense of approximately 620 KWh and a tax rate of 0.668220 is found, which results in an average monthly value of R $ 414.49 and an annual value of R $ 4,973.88. Through the costs of the Simulation Tables, the project's Investment Table was created, where the adopted TMA was 12%, giving a Simple Payback of six years and the Discounted in nine years, the NPV was R $ 14,088.73 and the IRR of 20%, in 25 years the estimated ROI is 398.47% grouped show the project's viability.
