Global Annual PV CapacityAdditions by Country From 2014 to 2023, global PV capacity additions grew from 40 GW dc to between 407 GW dc and 446 GW dc .-The spread in estimated global installations is due to uncertainty in Chinese reporting.-In 2023, global PV installs increased 73%-91% y/y. The total cumulative installed capacity for PV at the end of 2023 reached 1.6 TW dc .As of 2022, cumulative global PV capacity was about 1,200 GW dc .Analysts project that cumulative global PV installations will reach 2 TW dc -5 TW dc by 2030 and 4 TW dc -15 TW dc by 2050.Their results differ largely due to discrepancies in the projections of China's future capacity.IEA's Stated Policies Scenario (STEPS) uses assumptions based on the latest policy settings, including energy, climate, and industrial policies. IEA STEPS projects over 12.5 GW dc of PV capacity by 2050, with the United States, Europe, China, and India each having over 1 TW dc of cumulative capacity and China having over 6 TW dc of cumulative capacity.NREL | 9 NREL | 9 Chinese Generation Capacity Additions by SourceNote: Annual and cumulative solar values assume that China's National Energy Administration (NEA) reports distributed PV in direct-current terms and utilityscale PV in alternating-current terms.NEA reported 120 GW of utility-scale PV and 96 GW of distributed PV for 2023.On this slide, ac/dc conversions assume a dc-toac ratio of 1.1 for distributed PV.We use IEA-reported total capacity for W dc .
