Solar photovoltaic systems (PV) play a major role in the renewable energy transition taking place around the globe. E.g. in Germany, an early deployer of PV, 20% (45 GW) of installed electricity generation capacity was PV in 2018 [1]. Newcomers to the renewable energy transition are catching up quickly.
Solar power is vital for China''s future energy pathways to achieve the goal of 2060 carbon neutrality. Previous studies have suggested that China''s solar energy resource potential surpass the projected nationwide power demand in 2060, yet the uncertainty quantification and cost competitiveness of such resource potential are less studied.
The rapid expansion of photovoltaic (PV) power stations in recent years has been primarily driven by international renewable energy policies. Projections indicate that global PV installations have covered an area of 92000 km 2, equivalent to the entire land area of Portugal (Zhang et al., 2023b, Zhang et al., 2023c).Based on current growth rates, China''s
As China is the clear world leader in solar manufacture (as well as in deployment), China has much to gain from supporting roll-out of the ''spare'' solar capacity to developing countries. It would not be the first time that the government has supported deployment in order to bolster its solar manufacturing future.
