Análise da viabilidade econômica do projeto de um sistema fotovoltaico residencial considerando as disposições da Lei nº 14.300/2022.

Abstract

This study aims to analyze the impact of Law 14.300/22 on the financial return of solar energy utilization in a single-family residence in Paraíba, Brazil. The payback method was employed to compare the investment payback period before and after the implementation of the Law. The methodology involved the analysis of a solar photovoltaic microgeneration system in a residential setting and the calculation of the payback considering installation costs, maintenance expenses, and energy tariffs. The results of this study demonstrate that investments in distributed microgeneration projects remain economically viable with the implementation of Law 14.300/22.
