The target of solar photovoltaic (PV) power plant and rooftop power system is 12,139 MWp, a double capacity of the AEDP2015. It is remarkably that the PV floating system started in the AEDP2018 to achieve its target of 2,725 MWp. On the other hand, the target of solar heat consumption is downward to 100 ktoe. Based on the solar energy status, as shown in Table

Balancing the supply-demand dynamics while maintaining grid stability becomes a complex task, requiring sophisticated infrastructure and management systems. If these challenges can be overcome, rooftop solar PV has the potential to revolutionize the way energy is generated and consumed at the micro level.
As the global focus on sustainability intensifies, collaborating efforts from all stakeholders can drive the growth of rooftop solar PV, making it a vital pillar in the renewable energy landscape. Policy support remains a principal driver of solar PV deployment in most of the world (IEA, 2023).
Rooftop PVs are important solar resources, particularly at the city level [4, 5]. However, the pathway to achieve the PV installation goal remains unclear. The economic status and trends of rooftop PVs at the city level are valuable information for policymakers in implementing the target.
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
Shrestha and Raut (2020) assessed the technical, financial, and market potential of the rooftop PV system on residential buildings in three major cities of Nepal through a field survey instead of simulation, and the results showed that 35% of the city's annual electricity consumption could be covered by solar power.
