Global Solar Capacity Surpasses 3 TW as 2025 Sees Record 664 GW Installations

Global Photovoltaic Market Forecast and Direction Analysis (June 2026)

Current Market Status

• The global solar power fleet has surpassed 3 terawatts (TW) of installed capacity, achieving this milestone in early 2026.
• Solar energy now accounts for 9% of global electricity demand, significantly increasing from previous years.
• In 2025, a record 664 gigawatts (GW) of new solar capacity was installed, marking a 12% year-over-year increase.

Market Growth Trends

• The Asia-Pacific region dominated the market in 2025, contributing 73% of new installations (487 GW), with China alone accounting for 57% (382 GW).
• The global solar market is projected to contract by 8% in 2026, primarily due to a 24% decline in China's market following major changes to its solar market design.
• Despite the expected dip in 2026, growth is forecasted to resume, with global solar capacity anticipated to exceed 6.6 TW by 2030 under the Medium Scenario.
• The High Scenario suggests potential for 7.6 TW if supportive policies are enhanced.

Emerging Trends

1. Integration of Solar and Storage: Increasing emphasis on pairing solar power with battery storage to enhance energy security amid geopolitical uncertainties.
2. Technological Advancements: Innovations such as perovskite tandem cells, bifacial panels, and AI-powered smart solar monitoring systems are leading to higher efficiency and lower costs.
3. Policy Impacts: Recent policy changes are expected to influence the pace of solar PV capacity additions. Governments are urged to integrate solar into national energy security strategies and accelerate battery storage deployment.
4. Market Dynamics: The market faces oversupply and pricing pressures, causing a shift in competition from volume to execution and integration capabilities.
5. Sustainability and Recycling: Solar recycling is gaining priority, with increasing attention on managing end-of-life PV module decommissioning.

Challenges and Considerations

• Structural constraints such as grid congestion, insufficient storage, and permitting delays remain significant barriers to growth.
• The U.S. solar market is experiencing a decline in capacity additions, with a 27% decrease in Q1 2026 compared to Q1 2025.

Long-term Outlook

• The long-term outlook for solar remains robust, with projections indicating continued expansion and a pivotal role in global decarbonization efforts.
• Solar PV is expected to contribute substantially to the COP28 goal of tripling renewable energy capacity to 11 TW by 2030.

Conclusion

The global photovoltaic market is entering a new phase characterized by technological advancements, policy shifts, and changing market dynamics. While challenges such as market contraction and structural barriers exist, the overall trajectory remains positive, driven by increasing demand for clean energy solutions and innovative technologies.
