Unfortunately, rooftop solar PV users declined in 2022 due to new regulations regarding rooftop solar PV capacity limits. The capacity limit set is 10% -15% of the installation. As a result, many customer complaints regarding this regulation. Then, the Ministry of Energy and Mineral Resources and PLN revised the applicable regulations.
Although many studies [37,56,59,60] support the importance of rooftop photovoltaics in urban solar energy utilization, the potential of facades should not be overlooked. In summary, this research demonstrates the potential of applying GIS+LBT and ML to the prediction, analysis, and evaluation of solar radiation on urban building surfaces.
To best take advantage of the rooftop PV potential, effective analytic tools that support deployment strategies and aggressive local, state, and national policies to reduce the soft cost of solar energy are vital. A key step is the low-cost automation of data analysis and business case presentation for structure-integrated solar energy.
