description: "According to EIA data reviewed by the SUN DAY Campaign, solar, wind, and batteries are projected to provide over 99% of new US generating capacity in 2026. In November 2025, utility-scale solar generation increased by 33.9% compared to the previous year, contributing 7.2% to US electrical output. Overall, solar generation (both utility-scale and small-scale) grew by 28.1% from January to November 2025, accounting for nearly 9% of total US electrical generation, up from 7.1% in 2024."

Solar, wind, and batteries are set to supply virtually all net new US generating capacity in 2026, according to EIA data reviewed by the SUN DAY Campaign, continuing their strong 2025 growth.

## Solar set new records in November

EIA’s latest monthly “Electric Power Monthly” report (with data through November 30, 2025), once again confirms that solar is the fastest-growing among the major sources of US electricity.

In November alone, electrical generation by utility-scale solar (\>1 megawatt (MW)) expanded by 33.9% compared to November 2024, while “estimated” small-scale (eg, rooftop) solar PV increased by 11.0%. Combined, they grew by 27.5% and provided 7.2% of US electrical output during the month, up from 5.9% a year ago.

Moreover, utility-scale solar thermal and photovoltaic expanded by 34.5% while that from small-scale systems rose by 11.3% during the first 11 months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 28.1% and produced a bit under 9.0% (utility-scale: 6.74%; small-scale: 2.13%) of total US electrical generation for January to November, up from 7.1% a year earlier.
