This paper investigates the potential of rooftop photovoltaic (PV) systems in mitigating energy vulnerability in the urban context. Based on a geospatial data-driven approach, it combines georeferenced assessment of solar potential and high-resolution demand data with energy vulnerability indicators for both heating and cooling needs, to identify priority areas for supporting PV deployment. Results show more than 50% saving potential in the energy bill for the selected priority areas. The mismatch between PV supply and demand supports the development of demand-aggregating collective self-consumption approaches such as solar energy communities, whose challenges and opportunities are discussed.
