The U.S. solar energy sector is poised for significant growth, with 70 GW of new capacity expected in 2026-2027, representing a 49% increase from 2025 levels. This growth is projected to make solar the dominant source of new U.S. power capacity and surpass coal in total installed capacity before the end of 2026, indicating a strong investment opportunity in solar energy companies. The EIA forecast shows solar's share of total U.S. generation rising from under 5% in 2021 to nearly 10% by 2027, while coal declines from over 20% to around 15% in the same period.
