The authors found that reductions in costs of solar power and storage systems could supply China with 7.2 petawatt-hours of gridcompatible electricity by 2060, meeting 43.2% of the country's projected energy demand at a price lower than 2.5 US cents per kilowatt-hour.
China has already made major commitments to transitioning its energy systems towards renewables, especially power generation from solar, wind and hydro sources. However, there are many unknowns about the future of solar energy in China, including its cost, technical feasibility and grid compatibility in the coming decades.
This study aims to estimate China's solar PV power generation potential by following three main steps: suitable sites selection, theoretical PV power generation and total cost of the system.
The solar radiation varies widely across China, with the highest levels in Southwest China, especially the Tibetan Plateau, while the lowest radiation is observed over Northeast and Central China. Anthropogenic aerosols and other air pollutants are identified as significant factors influencing surface solar radiation and PV power generation.
Because of its favorable latitude and high annual sunshine hours, China is a prime site for solar photovoltaic (PV) power plants. Researchers in China have looked at the sun's potential in various areas, and their findings have shed light on how much energy the sun can produce.
Similarly, some researchers have previously estimated China's solar PV potential. Yu et al. (2023) utilized multi-criteria decision mode and random forest algorithm to calculate China's large-scale and distributed solar PV power generation potentials in prefecture-level cities.

Solar rooftop potential for the entire country is the number of rooftops that would be suitable for solar power, depending on size, shading, direction, and location. Rooftop potential is not equivalent to the economic or market potential for rooftop solar—it doesn't consider availability or cost.
With improvements in solar conversion efficiency, the rooftop potential in the country could be even greater. Residential and other small rooftops represent about 65% of the national rooftop potential, and 42% of residential rooftops are households with low-to-moderate income.
The coupled heat transfer process of rooftop photovoltaic shading units and indoor heat gain are analyzed. The energy-saving potential of photovoltaic rooftops compared to traditional rooftops is revealed. The energy-saving performance of photovoltaic and traditional rooftops under different roof reflectivity are summarized.
Realistically, your roof's solar generation potential will be less than that. It'll likely still exceed your typical household energy needs, but real-world constraints like roof space, sunlight exposure, and equipment specifications play a huge role in your panels' actual generation.
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.
