Motivated by the growing awareness of global warming, public health concerns and the fluctuating cost of fuels, this study presents investigates the energy and environmental implications of transitioning from conventional vehicles to EVs, combined with solar PV integration, within the Bus Rapid Transit (BRT) system of the Maputo Metropolitan Area (MMA). A physical model was developed to simulate the energy load profile of electric city buses. Route information was sourced from OpenStreetMap (OSM), and operational data were provided by the designers of the MMA BRT project. Solar resource potential in the region was evaluated using environmental data from PVGIS-SARAH 2, while shading analysis was conducted with the SunEarth Tool to identify potential obstacles affecting PV system performance. A PV system was designed specifically for the Zimpeto Terminal and Depot. The research examines the benefits, challenges, and possible solutions for integrating renewable energy into public urban mobility. At the national level, the study aligns with the fourth pillar of Mozambique’s Energy Transition Strategy (ETS), which prioritizes shifting from petroleum-based transport and private vehicles to electric public transportation. At the international level, the research supports the United Nations Sustainable Development Goals (SDGs) 7, 11, and 13 by promoting equitable access to sustainable, safe, and efficient public transport infrastructure in developing countries by 2030. The expected outcomes aim to provide valuable insights into integrating renewable energy in urban transport systems, highlighting the synergies between PV and EV technologies in reducing fuel consumption, private road traffic, and emissions of atmospheric pollutants.
