An increasing trend towards the installation of photovoltaic (PV) solar energy generation capacity is driven by several factors including desire for greater independence and, especially, to decarbonize industrial economies. While large ‘solar farms’ can be installed in relatively open areas, urban environments also offer scope significant generation, although heterogeneous nature surface fabric complicates task forming an area-wide view this potential. In study, we investigate potential offered publicly available airborne LiDAR data, augmented using data from OpenStreetMap (OSM), estimate rooftop PV capacities individual buildings and regionalized across entire small city. We focus on island Tromsøya city Tromsø, Norway, which located north (69.6° N) Arctic Circle, covers about 13.8 km2, has a population approximately 42,800. A total 16,377 were analyzed. Local was estimated between 120 180 kWh m−2 per year suitable roof with 200 GWh year, or 30% city’s current consumption. Regional averages within show variations highlighting importance orientation building density, suggesting that could play much more substantial role local supply than commonly assumed at such high latitudes. The analysis method developed here rapid, simple, easily adaptable other locations.

Toward cities' energy transition, historical urban areas are at risk of being abandoned due to inefficiency and high costs retrofitting. Deployment renewable solutions, such as solar technology, can strengthen resilience these by fostering independence lowering operational costs, while preserving their cultural value for both cities residents. However, the integration systems into culturally significant spaces, brings challenges barriers that require thoughtful multi-criteria evaluation prioritization safeguard inherent ensure future. In this paper, a literature review was conducted identify conservation criteria/challenges define successful implementation strategies in areas. The findings suggest non-invasiveness, compatibility, reversibility need be addressed. Additionally, legislative gaps emerge main barrier requires targeted interventions. study evaluates whether consistent with those found Møllenberg neighborhood Trondheim, Norway case area or specific tailored measurements. results offer insight potential solutions integrate technology increasing
