This study develops a systematic framework to classify European regions into homogeneous zones, allowing for a more data-driven and efficient strategy for integrating photovoltaic (PV) systems into the energy mix. In addition to assessing PV potential, it introduces average embodied emissions values for each category, providing a comprehensive evaluation of both feasibility and environmental impact. Given the significant variability in solar irradiance, grid carbon intensity, electricity demand, and land availability, a structured classification is essential to assess the feasibility of PV deployment beyond national or geographic boundaries. By grouping regions with similar characteristics, this approach enables a standardized evaluation of PV potential, ensuring that energy investments and policies align with regional conditions.
