Can a power grid interconnection improve solar power output in southern areas?

In contrast, southern areas do not have large solar energy resources during the summertime, because of the clouds and rain common during those days. Hence, a power grid interconnection between northern and southern areas could to some extent smooth the seasonal variation of renewable power output.

What is the contribution of solar energy to global electricity production?

While the contribution of solar energy to global electricity production remains generally low at 3.6%, it has firmly established itself among other renewable energy technologies, comprising nearly 31% of the total installed renewable energy capacity in 2022 (IRENA, 2023).

Where can solar PV be developed?

The largest potential for solar PV is also in the north, concentrated in Northwest China, in the provinces of Xinjiang, Gansu, Shaanxi, Qinghai, and Ningxia. A number of provinces in North China, such as Shanxi and West Inner Mongolia, are also endowed with large potential for the development of solar PV.

Does China have centralized photovoltaic power generation?

Zhang HY (2018) Economic research on centralized photovoltaic power generation in China. North China Electric Power University (Beijing), Dissertation (in Chinese) Zhang C, Su B, Zhou KL, Yang SL (2019) Decomposition analysis of China’s CO2 emissions (2000–2016) and scenario analysis of its carbon intensity targets in 2020 and 2030.

Is a high GHI threshold a feasible threshold for PV installation?

Since an annual GHI higher than 1400 kWh/m 2 and slope lower than 3 degrees has been widely used in previous studies as a threshold for PV installation to be feasible, here we conduct sensitivity analysis on these two key assumptions, and the result can be seen in Fig. 7.
