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

Since the photovoltaic power generation system does not fully utilize solar irradiance, the remaining is converted to heat, which leads to the overheating of the photovoltaic modules. One of the primary external factors that adversely impact a photovoltaic system''s capability to produce power is ambient temperature. Ambient temperatures range from 5.1°C to 47.6°C, while

Their incorporation into building roofs remains hampered by the inherent optical and thermal properties of commercial solar cells, as well as by esthetic, economic, and social constraints. This study reviews research publications on rooftop photovoltaic systems from building to city scale.
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.
It can be found that the use of crystal silicon cells in public buildings is still the main approach of rooftop photovoltaic projects, and the maximum installed capacity of single building has exceeded 10,000 kWp. Finally, on the basis of summarizing the previous achievements, the future research focus and directions are predicted. 1. Introduction
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.
Public buildings are the main applications of PV roofs. The roof shape greatly influences the design of the PV system. The selection of BIPV or BAPV and of PV cell materials should be based on local characteristics.
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014).
