Photovoltaic solar microgeneration connected to the electric grid in brazil

an economic feasibility analysis

Abstract

The current situation around the world, especially in the Brazilian electricity sector, has contributed to expressive readjustments in electricity tariffs, which substantially increases the viability conditions for microgeneration. In this way, this research has the general objectiveof analyzing the economic feasibility for the implementation of a project of Photovoltaic SystemsConnected to the Electric Grid (SFCR), and, as specific objectives, there is the identification of the economic attractiveness of micro and minigeneration of residential consumers as well as their relationships with conventional electricity rates. A hybrid methodology is adopted, with concomitant support in the literature review and in the traditional and published aspects of the associated traditional financial and economic analyses. The assessments related to the Net Present Value (NPV), Internal Rate of Return (IRR) and Payback (return on investment time)are used to determine whether or not a project justifies its investment over time. In conclusion, the political incentives adopted by Brazil are presented, emphasizing the normative Resolution ANEEL 482/2012, which deals with the general conditions for microgeneration and distributed minigeneration access to electrical systems and creating the energy compensation system.
