Análise da viabilidade econômica da implementação de módulos fotovoltaicos em um consumidor do tipo A4

Abstract

The growing concern with the preservation of the environment and the search for the diversification of the electric matrix is on the rise in Brazil and in the world. These factors, coupled with the increased demand for energy and industry development, have boosted the world's electricity generation from renewable sources. Among these, one with great potential for growth in the coming years is Photovoltaic Energy. Within this scenario, only in 2012 with Normative Resolution (REN) 482, that any consumer can generate its own energy, in Brazil. Thus, the present work analyzes the financial viability of the insertion of photovoltaic modules in a client of group A4. The study carried out based on the mass memory of this client, located in the city of Santa Maria -RS, analyzes economic viability through economic indicators such as: Net Present Value (NPV), Simple Payback, Discounted Payback and Internal Rate of Return (IRR). The financial analyzes were performed with the help of Microsoft Excel software. As a basis for the analyzes, we considered the energy tariffs of the local power utility, the budgets obtained for the implementation of Photovoltaic System, the rates commonly used in the market and the relevant taxes in the area of operation. Thus, the analysis was carried out for six (6) scenarios, four of them for total consumption and two for the partial consumption of the customer. The results show that in three (3) of the six (6) scenarios the investment on Photovoltaic System is preferable to another standard market investment.
