IEA PVPS: Installed PV capacity exceeds one terawatt

The International Energy Agency (IEA) has published the »Trends in Photovoltaic Applications« for the year 2023. According to this report, PV systems with a cumulative capacity of more than one terawatt were installed worldwide at the end of 2022. This was to be expected, as the previous year's report already documented a total capacity of 945.7 gigawatts (GW; in the meantime slightly corrected to 950.2 GW). With an addition of 235.8 GW, the terawatt mark even was clearly exceeded; the IEA now counts a total of 1.183 terawatts. Moreover, the pace of expansion is likely to continue to pick up significantly: The authors also see significant investment in new silicon, cell and module manufacturing capacity of up to 716 GW.
By comparison, the International Renewable Energy Agency (IRENA) had indicated an addition of 191.45 GW of PV capacity in its annual statistics published in March, with a total capacity of 1.053 terawatts at the end of 2022.
The annually updated report is produced as part of the IEA Photovoltaic Power System Programme (IEA PVPS) and analyzes the development of the global solar market.
