The research team developed an integrated model to assess solar energy potential in China and its cost from 2020-2060.
China has emerged as a leading player in the global solar PV market. According to China's National Energy Administration (NEA), the country added 54.88 GW of solar PV capacity in 2021 comprising approximately 29.28 GW of distributed generation and 25.60 GW of centralized solar PV.
New and cumulative installed capacities of China's solar PV power from 2000 to 2017. In order to effectively coordinate the scale and speed of the solar PV installation with the economic development, China has occasionally set and adjusted the development targets for solar PV power.
This study constructs an energy-economy-environment integrated model by way of a dynamic programming approach to explore China's solar PV power optimal development path during the period 2018–2050 from the perspective of minimum cost.
The total potential for solar radiant energy is 1.7 × 1012 tons of standard coal equivalent per year for the country (Zhang et al., 2009a). China started generating solar photovoltaic (PV) power in the 1960s, and power generation is the dominant form of solar energy (Wang, 2010).
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.
