This research investigates the possibilities of using grid-connected photovoltaic systems (SFCR) in low-income communities, aiming to comprehend how these systems can be employed as tools to promote social inclusion. The overall objective of the research is to analyze the use of SFCR in low-income communities in Brazil, seeking to understand how these systems can foster social inclusion and drive a fair energy transition. Additionally, this study explores the connection between the use of SFCR and the concept of social technology. To enrich and deepen the research, the methodology of bibliographic research and documentary analysis with a qualitative approach was adopted. An extensive search was conducted across different databases such as SciELO, Capes platform, and Google Scholar, with the aim of locating relevant and updated materials to support the study consistently and comprehensively. The selected companies for documentary analysis were REVOLUSOLAR and SOLAR PILAR, both located in Rio de Janeiro. Documentary data and official information provided by the projects were collected to understand their structures, operations, and implementation approaches. The analysis was carried out in accordance with the Multidimensional Evaluation Matrix, allowing the identification of how these projects aligned with the studied concepts. Through documentary analysis, it was possible to investigate how these projects incorporated the principles of social technology, social economy, fair energy transition, and community self-management, contributing to a deeper understanding of the practical application of these concepts in real contexts. Therefore, the use of SFCR in interactive processes involving community participation to solve local issues proved to be a versatile strategy, adaptable to different projects. In Brazil, national public policies, traditionally focused on education, health, income supplementation, and housing, aimed to address urgencies and gain political recognition. However, projects related to renewable matrices remained considered alternative, often experimental and localized, with slow growth due to their limited impact. The analysis of two existing projects revealed that, despite social and tariff incentives, Brazil still lacked public policies for a fair energy transition, requiring greater attention to approaches presented in the research. The Renewable Social Energy Program (PERS) stood out as an opportunity for significant advancements in the use of SFCR in low-income communities, promoting social inclusion in the energy transition. For the success of PERS, it was crucial for public policies to focus on the most vulnerable communities, promoting community self-management and entrepreneurship through the formation of renewable energy cooperatives and providing training for the autonomous management of renewable energy systems.
