Viabilidade econômica de sistemas de energia fotovoltaica on grid em habitações unifamiliares

Abstract

Based on the need to produce electricity from renewable sources, the present economic feasibility study emerged, focusing on grid-connected photovoltaic energy systems in single-family homes. The diffusion of this energy matrix will provide its access to the most socioeconomically vulnerable classes, enabling less environmental and financial impact on energy production and consumption. The sizing of the photovoltaic system was designed in a residence in the southern region of Goiânia, with the collaboration of the company J & A Construtora Sustainable Solutions and the Solar Portal simulator, in compliance with ANEEL Normative Resolutions 482/2012 and 687/2015. Economic viability was analyzed using the tools of financial mathematics (IRR, NPV, IL, Payback). After data analysis, the Photovoltaic System project proved feasible, with an Internal Return Rate (IRR) of 10.31%. In the case of discounted payback, the financial return occurs in 11 years and 9 months.
