Rooftop photovoltaic system plays an important role in solar energy power generation especially in urban. In this paper, we present an assessment method for the PV power generation potential of rooftop in China.
It has entered a rapid development stage (Li and Huang, 2020, Anon, 2022a). There are 676 rooftop solar photovoltaic (RTSPV) pilot projects in 31 provinces in China in 2021 (Anon, 2021a). Rooftop solar photovoltaics use building roof resources to design distributed photovoltaic power stations (Tripathy et al., 2016).
The research results of this paper can roughly provide suggestions for the rooftop distributed photovoltaic development strategy in China, and help decision makers analyze photovoltaic potential and CO2mitigation ability. Funding
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 conclusion is that the national rooftop distributed photovoltaic development potential is 2597.64 GW and the power generation potential is 3265.41 TWh/year. Tianzhi Qiu et al. use SSR radiation data with a resolution of 10 km * 10 km, and the power generation factor (kWh/ m2) is calculated by combining with temperature data (Qiu et al., 2022).

The major solar power technology currently available is the solar PV system, in which sunlight is directly converted into electricity via photovoltaic effect. The PV industry in China entered its period of rapid development during the 21st century because of the significant increase in global demand for PV products.
During the 1980s, China introduced several photovoltaic (PV) cell production lines from the United States, Canada, and other countries, which eventually formed the solar PV industry in China . By the end of the 1990s, a number of component packaging plants were built.
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.
With the rapid evolution of technologies in the solar PV industry, China can no longer simply rely on its manufacturing ability and price advantage to continue to dominate the market. Instead, the industry must resort to strategies that intensify innovation in order to stay ahead of the game.
China has pushed the boundaries of solar technology with its latest innovation: a solar panel powered by a “miracle material. ” This new development could redefine global energy production and deliver higher efficiency at a lower cost. The innovation comes from Longi, one of the world's top solar. China's solar power generation overtook wind for the first time last year as a boom in cheap panels continues to reshape the country's grid and climate trajectory. 17 million gigawatt-hours of electricity from solar power in 2025, up 40% on a year earlier, the National Bureau.

In 2020, China's newly installed grid-connected photovoltaic capacity reached 48.2GW, a year-on-year increase of 60.1%, of which the installed capacity of centralized photovoltaic power plants was 32.7GW, a year-on-year increase of 82.68%; the installed capacity of distributed photovoltaic power plants was 15.5GW, a year-on-year increase of 27.04%.
BEIJING -- China's installed capacity of distributed photovoltaic power generated by households has reached about 105 million kilowatts by the end of September, covering more than five million households in the country's rural areas, data from the National Energy Administration (NEA) showed Tuesday.
In recent years, China's distributed photovoltaic power generated by households has developed rapidly, the NEA said, adding that this has played a vital role in ensuring the safe and reliable supply of electricity, promoting the green transformation of energy as well as driving the growth of farmers' incomes.
In the first three quarters, the newly added installed capacity of household photovoltaic power stood at 32.98 million kilowatts, accounting for about half of the newly installed capacity of distributed photovoltaic power, according to the data.
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.
Wind and solar now account for 37% of the total power capacity in the country, an 8% increase from 2022, and widely expected to surpass coal capacity, which is 39% of the total right now, in 2024. Cumulative annual utility-scale solar & wind power capacity in China, in gigawatts (GW)
China added almost twice as much utility-scale solar and wind power capacity in 2023 than in any other year. By the first quarter of 2024, China's total utility-scale solar and wind capacity reached 758 GW, though data from China Electricity Council put the total capacity, including distributed solar, at 1,120 GW.
