The solar radiation prediction, the 3D building model, and the estimation of the available roof area are essential in evaluating a building's potential for solar rooftop PV energy generation.
Rooftop solar PV installations in China may surge in the next three years as the country goes through a green energy transition and plans to make renewable energy a key cornerstone in the country's path to a greener economy, a recent research report said.
This approach was applied in Shanghai, China (except for Chongming Island). The total building rooftop area of Shanghai was 253.0 km 2 and the total rooftop obstacle area was 37.7 km 2. The estimated annual rooftop solar radiation potential of Shanghai was 257,204 GWh, with a corresponding estimated annual PV power generation of 49,753 GWh.
The country's rapid development of rooftop solar capacity is also driven by government incentives. Newly added annual installed capacity for solar stations has been around 30 GW on average over the past few years, China New Energy Investment and Financing Alliance said.
The northwest region, with its solar potential, is a focal point for distributed PV growth, which has already exceeded 50% of the energy mix by 2021. This study assesses the rooftop PV potential in five northwestern capitals, finding favorable conditions such as ample space, dense populations, and high sunlight exposure.
The research underscores the significant role of rooftop PV in achieving China's energy and climate goals in its northwestern urban centers. In China, more than 75% of electricity is still generated using "dirty" coal, resulting in substantial emissions of NO x, CO 2, and SO 2 into the environment.
The assessment of rooftop solar potential is vital for optimal photovoltaic (PV) system placement and renewable energy policy in dense urban areas. Complex shading from buildings and diverse rooftop obstacles have posed significant challenges to this evaluation.

[PDF Version]Finally, the study presented one economic analysis model to evaluate the profitability by combining the market cost of rooftop PV systems and electricity prices in China. The economic model included four indicators: payback period (static and dynamic), net present value (NPV), and internal rate of return (IRR).
The results show that: For small rooftop photovoltaic in China, first of all, under the existing subsidy price and cost, its investment payback period is short and the risk is low. Secondly, the average internal rate of return is more than 10%, and the levelized cost of electricity is 0.2727–0.5573CNY/kWh, so the economic performance is good.
The growth of Residential rooftop solar (RRS) in some western countries has predominantly been driven by individual or market behaviour and has been extensively studied. However, the development landscape of RRS in China differs, and its driving mechanisms remain unclear.
According to the data in the table, it can be found that under the existing national subsidy policies, rooftop PV in these five regions has a very good economic performance. Considering the influence of other unstable factors in a year, the radiation amount range of China's five solar resource regions is 928-2333 kWh/m 2 [ 1 ].
1. Introduction Residential rooftop solar (RRS) for electricity generation is essential in the new power system and vital during the low-carbon green energy transformation, which is being adopted globally (Moore and Bullard, 2021). In recent years, China's RRS has been expanding rapidly, with the annual growth rate ranking first in the world.
For example, Ref.6 studied the impact of solar radiation amount of rooftop PV on economic benefits, and concluded that self-use PV system with the optimal inclination and more than 1000 kWh annual radiation amount is feasible globally.
Chinese scientists have announced a plan to build an enormous, 0. 6 mile (1 kilometer) wide solar power station in space that will beam continuous energy back to Earth via microwaves.
Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.
Thirdly, a variety of photovoltaic building integration modules are used, with a total solar power generation power of about 400 KWp, making it a benchmark project for photovoltaic building integration in China , as shown in Table 10.
In the first nine months of 2017, China saw 43 GW of solar energy installed in the first nine months of the year and saw a total of 52.8 GW of solar energy installed for the entire year. 2017 is currently the year with the largest addition of solar energy capacity in China.
Due to the acceleration of the construction of modern urbanization projects in China, land is becoming increasingly scarce. The combination of photovoltaic systems and buildings can be developed and utilized to the greatest extent, so it is particularly suitable for promotion and application in large and medium-sized cities .
Photovoltaic research in China began in 1958 with the development of China's first piece of monocrystalline silicon. Research continued with the development of solar cells for space satellites in 1968. The Institute of Semiconductors of the Chinese Academy of Sciences led this research for a year, stopping after batteries failed to operate.
As such, critics argue that investments into renewable energy sources such as solar power are means to increase the power of the central state rather than protect the environment. This argument has been complemented by China's expansion of fossil fuel plants in conjunction with solar energy.

Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.
Of the total global solar PV capacity, 35.45% is in China. Listed below are the five largest active solar PV power plants by capacity in China, according to GlobalData's power plants database. GlobalData uses proprietary data and analytics to provide a complete picture of the global solar PV power segment.
Located in Datong City, Shanxi Province, it is the country's 3rd largest solar power plant. China's National Energy Administration aimed to install solar plants in this area. After successful completion of the project's 1st phase in 2016, this solar plant now has a total capacity of 1.1 gigawatts.
“In eastern China, PV power stations mainly locate in Anhui, Jiangsu, Shandong, Henan, Hubei and Jiangxi Province, while in southwestern China, Guizhou, Yunnan and Sichuan witnessed the most PV power stations.” Concluding the article, the academic group said it will release in the future new maps that are based on data from different years.
In June 2024, China activated the world's largest solar power facility, a 3.5-gigawatt (GW) installation in Urumqi, Xinjiang. Built by Power Construction Corporation of China, this plant produces around 6.09 billion kilowatt hours (kWh) of electricity annually.
As of at least 2024, China has one third of the world's installed solar panel capacity. Most of China's solar power is generated within its western provinces and is transferred to other regions of the country.
