This mismatch has left solar facing constraints due to limits in the ability of China’s grids to shift power across its vast distances. The output of solar plants in the northwest has frequently ended up curtailed, as there’s no capacity to send it where it’s needed. As a result, it’s been somewhat difficult to fully understand the economics of solar power in China. To get a clearer picture, the researchers built a model that takes into account most of the factors influencing solar’s performance. The model tracks changes in technology, economics, solar resources, and the Chinese grid for the period from 2020 to 2060. It used six years of satellite weather data to estimate typical productivity in different areas of the country, and it included information on existing land use that would interfere with solar-farm siting.
