a, Choropleth map of the potential rooftop PV electricity generation, TWh km−2 at Nomenclature of Territorial Units for Statistics classification (NUTS3) regional level for NRBs with floor areas exceeding 250 m2. b, Heat map of the rooftop PV technical capacity potential (GWp) for NRBs across floor area category (0 m2–250 m2, 250 m2–1,000 m2, 1,000 m2–2,000 m2 and over 2,000 m2), following the EPBD classification. Countries are sorted from higher to lower rooftop PV capacity for the 2,000-m2 floor area category.
