(1) This study designs a dual-branch framework for a comprehensive assessment of regional rooftop PV development based on remote sensing imagery and deep learning semantic segmentation technology, which simultaneously considers the detailed information of existing rooftop PV and estimates the PV potential of remaining roofs.
The framework for assessing the development of regional rooftop PVs. Secondly, in the target object extraction module, the SSN_Roof and the SSN_PV are used to predict all the remote sensing images of the study area, resulting in the binary maps of the roof and PV panel extraction results, respectively.
The results of the potential assessment can provide decision support for the government to promote the installation and utilization of rooftop PV systems, thereby improving the energy supply structure, reducing environmental pollution and resource pressure, and promoting the development of the regional green economy.
By understanding the development status of existing rooftop PV, the government can obtain detailed installation capacity and distribution information, so as to scientifically evaluate the utilization of existing distributed PV resources and potential growth points.
In response to the problem that previous studies did not consider the PV already installed on rooftops and thus had a low level of refinement, this study proposes a dual-branch framework based on remote sensing imagery and deep learning to effectively monitor the current status and estimate the future potential of regional rooftop PV installations.
Compared with other forms of PV power generation, rooftop PV uses building roofs, such as residences and commercial buildings, to generate electricity. It has the advantages of low cost, fast construction, and extra income from selling excess electricity.
