The United Nations (UN) created an agenda for the year 2030 with 17 goals to be achieved (“Sustainable Development Goals” (SDGs)). Among them, we found: “clean and accessible energy”, which was sought in number seven, whose objective is: “to ensure access to reliable, sustainable and modern energy sources for all”. This work is based on the problem of energy poverty in Brazilian favelas. It explores the use of the solar resource through distributed solar photovoltaic production as part of the solution to reduce this social, economic, and environmental scourge. Energy poverty in Favela da Babilónia was quantified through pre-defined indicators to understand the scale of the problem. Using a model and case study of a favela in Babilónia, in Rio de Janeiro, this work presents a methodology for solar mapping and assessing the potential for photovoltaic generation using aero photogrammetry while establishing partnerships with local agents (for example, NGO Revolusolar). Therefore, we mapped Babilónia by zones to realize a renewable energy community for each stipulated zone. An analysis of selected areas in the favela was carried out for 3D modelling of the dwellings and the configuration of the most advantageous panels. Thus, it is possible to stipulate the power for each photovoltaic system, financial factors for the project investment. The main results of this work were the assessment of 7 different zones dividing the fa-vela (C, E, F, H, I, J and K), with a total investment of R$ 800.000,00 (€ 128.000,00) for the construction of 8 photovoltaic plants with a potential of 182 kWp, covering 12 different roofs. The full implementation of the project would produce around 239,766 kWh per year, covering the consumption of 148 residences in the community. The priority for the construction of each solar PV system would be in this order: C, J, H, E, K1 + 1, F, I, and K1.
