Global Solar PV Capacity Hits 1.5 TW as Adoption Reaches Record High in 2025

The global solar photovoltaic (PV) industry has achieved a historic milestone, with total installed capacity surpassing 1.5 terawatts (TW) in 2025, according to the International Renewable Energy Agency (IRENA). This represents a 20% increase from 2023, driven by massive deployments in China, the U.S., and Europe. China remains the dominant market, adding over 120 GW of new solar capacity in 2024 alone, while the U.S. set a new record with 40 GW installed last year, fueled by the Inflation Reduction Act (IRA). Europe saw a 35% year-on-year growth, led by Germany, Spain, and the Netherlands, as the region accelerates its energy transition. Emerging markets like India, Brazil, and Southeast Asia are also experiencing rapid expansion due to declining solar module prices and favorable policies. The average cost of solar panels has dropped by 12% since 2023, further boosting adoption, while advanced technologies like bifacial and PERC modules now dominate 60% of new installations. Energy storage integration is also rising, with over half of new utility-scale solar projects incorporating batteries for grid stability. "Solar PV is now the fastest-growing energy source worldwide," said Emma Chen, IRENA’s Lead Analyst. "With sustained policy support and innovation, solar could supply 30% of global electricity by 2030." The report highlights the critical role of solar in achieving net-zero emissions but calls for improved grid infrastructure and faster permitting to maintain growth momentum.
