However, optimizing the placement of PV panels on rooftops remains a complex task due to factors like building shape, location, and the surrounding environment. This study introduces the Roof-Solar-Max methodology, which aims to maximize the placement of PV panels on urban rooftops while avoiding shading and panel overlap.
Using Guangzhou, a city in southern China, as an example, we offer four installation scenarios based on rooftop area data and research on relevant characteristics and analyze the technical and economic potential of PV power generation on the rooftops of urban buildings.
Yet, only limited information is available on its global potential and associated costs at a high spatiotemporal resolution. Here, we present a high-resolution global assessment of rooftop solar photovoltaics potential using big data, machine learning and geospatial analysis.
Considering the capacity of each of the 1574 panels organized by the algorithm, this distribution achieved a PV solar potential of 393.5 kW in the studied district. Table 2 provides a detailed summary that includes the number of PV panels used per rooftop, the percentage of area utilized, and the total installed PV power.
This research also holds broader implications for sustainable urban development and energy policy. By maximizing solar energy production on rooftops, cities can reduce greenhouse gas emissions and harness economic opportunities from feeding excess energy into the grid, supporting the global transition toward renewable energy.
We assumed that the estimated building footprint is representative of the available rooftop area in each FN i.e., 100% of the estimated rooftop is available for solar panel installation. To install 1 kWp of roof-mounted solar PV, 10 m 2 of rooftop area is required, which is in line with the thin film technology currently in use.
