Abstract: The purpose of this study is to analyze the impact on the income of families benefiting from the “Minha Casa Minha Vida” Brazilian Social Housing Program through the integration of photovoltaic (PV) generation systems into housing financing, as outlined by Law 14,620 enacted in July 2023. Given the novelty of this legislation, there is no existing database for analysis. Consequently, simulations of PV generation were carried out for the typical dwellings provided by the program across the five macro regions of Brazil. The simulation takes into account maintenance and equipment replacement costs, tariff rules, and standard adjustment rates in the country. Across all examined scenarios, the installation of residential rooftop PV systems yielded favorable outcomes, resulting in a reduction in electricity costs for the low-income population. Making provisions for a Sinking Fund in the program was identified as crucial to provide sustainability, long-term operation, maintenance and replacement. Additionally, it was observed that civil construction companies play a crucial role in popularizing the proposal. In conclusion, legislation incorporating PV generation into the national housing program represents merely the initial step toward realizing the widespread adoption of this energy generation technology in the country.
