Global Solar Additions Hit All-Time Record in 2025: 600+ GW in a Single Year
Global solar power installations in 2025 shattered previous records, with leading energy research organizations reporting between 605 and 664 GW of new solar PV capacity added — the first year to surpass 600 GW. The milestone pushed cumulative worldwide solar capacity past 3 terawatts for the first time in history. China drove nearly two-thirds of global additions, while India displaced the United States as the world's second-largest solar market. Despite the record-breaking year, multiple forecasters anticipate a contraction in 2026 as China's market reaches saturation.
claim: Global solar power capacity additions in 2025 set an all-time annual record, with leading energy research organizations reporting between 605 and 664 GW of new solar PV installed, pushing cumulative global solar capacity past 3 terawatts for the first time.

Findings
- The world installed more solar capacity in 2025 than in any previous year, with IEA reporting 605 GW and SolarPower Europe reporting 664 GW of new solar PV added globally.
- Global cumulative solar capacity surpassed 3 terawatts in early 2026, with the world tripling installed solar capacity in under four years.
- China accounted for 57–67% of all global solar additions in 2025, while India overtook the United States to become the second-largest solar market globally.
- Despite the record 2025 performance, BloombergNEF and others forecast 2026 will be the first year of declining solar additions in over two decades, driven by Chinese market saturation and policy shifts.
Energy developers, grid operators, and government planners would use UVRN here to verify whether independent research organizations agree on the scale of the solar buildout — critical when allocating capital or setting grid integration targets where the difference between 510 GW and 664 GW carries real infrastructure implications.
