Solar capacity additions statistics worldwide in 2025

Global solar PV capacity additions rose by around 12% in 2025 and surpassed 600 GW for the first time. The International Energy Agency (IEA) says its 2025 figures include actual and estimated additions for regions where full-year data was not yet available. The estimate therefore describes a worldwide annual total assembled from both reported and estimated regional figures. Source: IEA, Global Energy Review 2026 — Technology: Solar PV and wind

The scale of deployment was also broad across countries: 30 countries installed over 1 GW of solar PV in a single year in 2025. That count signals that gigawatt-scale annual installations were not confined to a handful of the largest markets, although it does not show how much each of those 30 countries installed.

For context, global annual additions across all renewable technologies reached 800 GW in 2025, an increase of 16%. This is a broader renewable-energy measure, not a solar-only figure. Solar PV’s total of more than 600 GW is one part of that wider expansion; the two numbers should not be treated as interchangeable.

Solar capacity additions statistics by major market

The IEA’s selected 2025 market figures show large annual additions in Asia, Europe, Africa and the Middle East. The reported descriptions vary—some say “nearly,” “almost,” or “around”—so those qualifiers are retained rather than converted into exact totals.

MarketSolar PV additions in 2025
ChinaNearly 370 GW
European UnionAlmost 70 GW
Germany17 GW
Spain14 GW
IndiaAlmost 50 GW
South AfricaOver 3 GW
Saudi ArabiaNearly 7 GW
PakistanAround 10 GW

China’s nearly 370 GW of commissioned solar PV capacity stands out among these examples. The European Union installed almost 70 GW, with Germany adding 17 GW. The IEA says Germany’s amount accounted for one-quarter of total EU solar PV additions. Spain recorded 14 GW, described as a record in the report. These are national and regional totals, so the EU figure includes member-state activity such as Germany and Spain; they should not be added together as separate, non-overlapping markets.

India commissioned almost 50 GW of solar PV in 2025. South Africa installed over 3 GW, which the IEA identifies as the country’s first year above that level. Saudi Arabia’s additions reached nearly 7 GW. Pakistan recorded around 10 GW, driven almost entirely by on-grid and off-grid distributed systems. These examples describe different market structures as well as different scales: Pakistan’s reported total is especially associated with distributed installations, while the figures do not provide a comparable segment breakdown for every country.

Solar capacity additions statistics in 2024

The IEA reports that worldwide solar PV additions totaled about 550 GW in 2024, nearly 30% above the previous year. As with its 2025 total, the report says the 2024 figure is based on actual and estimated additions. The global figure is consequently an annual deployment estimate, not a single count drawn only from complete final reports in every region. Source: IEA, Global Energy Review 2025 — Electricity

The major-market examples show how that global total was distributed. China’s 2024 solar PV additions exceeded 340 GW, measured in direct current (DC). Utility-scale plants drove over 60% of China’s PV expansion, followed by distributed commercial and industrial installations. The country’s residential PV market was 30 GW and accounted for less than 10% of its solar PV additions. These details distinguish the scale of China’s total from the composition of its deployment: utility-scale plants led, while residential systems represented a smaller portion.

The European Union installed around 60 GW of solar PV capacity in 2024, a level the IEA describes as similar to 2023. The United States added almost 50 GW of new solar PV capacity to the grid, surpassing its previous record from 2023. India installed around 30 GW. Brazil added over 16.5 GW, with the IEA describing contributions from large utility-scale additions and continued distributed-resource deployment. These figures retain each source’s original qualifiers and reporting scope; they are not presented as perfectly harmonized national accounting. Source: IEA, Global Energy Review 2025 — Electricity

solar capacity additions: Solar PV capacity additions across regions

IRENA reports 451.9 GW of solar PV power capacity added worldwide in 2024. Its regional and country highlights identify Asia as the largest region in the reported examples, with 327.1 GW of solar capacity added. IRENA also gives 247.9 GW for Asia in 2023, but that prior-year value is not required to interpret the 2024 total and is not used here as a separate trend calculation.

IRENA separately describes worldwide solar power capacity growth as 452 GW, or 32.2%, in 2024. That rounded solar-power measure sits alongside the more precise 451.9 GW figure for solar PV additions. The report identifies solar photovoltaic as accounting for almost all of the increase in solar power. Keeping the rounded solar-power figure distinct from the PV-specific number preserves the source’s difference in wording and precision. Source: IRENA, Renewable Capacity Highlights 2025

The country figures illustrate the concentration of additions within the regional total: China added 278.0 GW and India 24.5 GW. Outside Asia, IRENA lists 38.3 GW for the United States, 15.2 GW for Brazil, and 15.1 GW for Germany; South Korea added 3.1 GW. These are 2024 additions as reported by IRENA, not capacity stocks. The report’s highlights and its companion capacity-statistics publication are presentations of the same data vintage, so overlapping values are not independent observations.

U.S. solar capacity additions by market segment

The Solar Energy Industries Association (SEIA) reports that the U.S. solar industry installed 43.2 GWdc of capacity in 2025. The unit is direct-current gigawatts. The executive summary gives this figure in both its key figures and introduction sections. Source: SEIA and Wood Mackenzie, U.S. Solar Market Insight, 2025 Year in Review Executive Summary

U.S. market segmentInstalled capacity in 2025
Utility-scale34.7 GWdc
Residential4,647 MWdc
Commercial2,345 MWdc
Community solar1,435 MWdc

Source for all table figures: SEIA and Wood Mackenzie, U.S. Solar Market Insight, 2025 Year in Review Executive Summary

The utility-scale segment installed 34.7 GWdc. Residential installations totaled 4,647 MWdc, commercial solar added 2,345 MWdc of new capacity, and community solar installed 1,435 MWdc. SEIA describes commercial solar as growing 6% in 2025. The source reports these segment measures using MWdc or GWdc; the table preserves those units instead of converting them into a common unit.

solar capacity additions: Historical U.S. solar PV capacity context

Annual additions describe capacity installed during a period; capacity stock describes the amount estimated to be in service at a point represented by the annual record. EIA’s Electric Power Monthly table reports estimated net summer solar PV capacity from utility and small-scale facilities, in megawatts. Its annual totals provide historical context, but they are not annual additions. Source: EIA, Electric Power Monthly, Table 6.1.A

YearEstimated total net summer solar PV capacity
201632,958.0 MW
202193,151.1 MW
2023138,302.4 MW
2024175,288.2 MW
2025211,046.5 MW

Source for all table figures: EIA, Electric Power Monthly, Table 6.1.A

For 2025, EIA’s estimated net summer capacity total includes 151,958.0 MW of utility solar PV and 59,088.5 MW of estimated small-scale solar PV. The table identifies the 2025 values as final. Those figures are components of capacity stock and should not be confused with SEIA’s 43.2 GWdc of solar industry installations during 2025: the sources describe different measures, and the EIA values are not annual additions.
