City-scale analysis of PV potential and visibility in heritage environment using GIS and LiDAR

A city-scale analysis reveals that Budapest, despite its dense urban environment and heritage protection constraints, holds significant potential for rooftop photovoltaic (PV) energy generation. The study, leveraging GIS and LiDAR data, estimated the PV capacity of nearly 190,000 buildings, considering factors like roof slope, orientation, and global irradiation. It introduced an open-access tool, the Budapest Solar Map, providing decision-makers with solar PV data. However, heritage protection regulations limiting visibility in this UNESCO World Heritage Site pose challenges to fully utilizing this potential.
