Abstract

Objective – This article sought to answer: does residential solar photovoltaic microgeneration remain economically viable under the new legislation, compared to the previous regime?

Methodology – A case study was conducted in a residence located in Juiz de Fora, Minas Gerais, with an average monthly consumption of 425 kWh. The analysis compares the Internal Rate of Return (IRR) and Payback indicators in the two regulatory scenarios.

Originality/Relevance – The recent change in the regulatory framework for distributed generation in Brazil, with the entry into force of Law 14,300/22, which establishes the Legal Framework for Distributed Generation, generated debates and doubts regarding the economic impact of the regulatory change for consumers, and the continued economic attractiveness of these systems, especially in light of the previous rules of ANEEL's Normative Resolution 482/2012, making the study of this topic extremely relevant.

Results – The results indicate that the difference observed does not have a significant impact on the feasibility of implementing photovoltaic panels. However, the need for more in-depth studies on the topic is highlighted.

Theoretical/Methodological Contributions – Indicate the main theoretical and/or methodological implications that were achieved through the findings of the study carried out.

Social and Environmental Contributions – Indicate the main social and environmental implications achieved through the findings of the study carried out.
