The solar energy industry is poised for significant growth in 2025 and beyond, with new capacity additions, evolving market trends, and technological advancements shaping the future of energy production. The U.S. solar sector, supported by government policies and private investment, is on track to become the dominant source of new power generation. This article explores the latest trends, challenges, and opportunities in the solar industry based on recent reports from the U.S. Department of Energy, National Renewable Energy Laboratory (NREL), and the U.S. Energy Information Administration (EIA).

Surging Solar Capacity Additions


According to the EIA, solar energy is expected to lead the U.S. electricity generation expansion, with utilities and independent power producers adding 26 gigawatts (GW) of solar capacity in 2025 and an additional 22 GW in 2026. This follows the record-breaking 37 GW of solar power capacity added in 2024, nearly doubling the capacity increase from 2023. The trend underscores solar’s role in replacing coal and reducing dependency on natural gas.

Furthermore, wind energy is expected to see steady growth, adding 8 GW in 2025 and 9 GW in 2026. However, natural gas-fired capacity growth has slowed significantly, and coal-fired power plants are facing accelerated retirements, with 11 GW of coal capacity expected to be removed in 2025.

Cost Declines and Price Trends


​Solar energy’s continued expansion is largely driven by declining costs. The International Renewable Energy Agency (IRENA) reports that the global weighted average levelized cost of energy (LCOE) for concentrating solar power (CSP) fell by 70% from 2010 to 2023, reaching under $0.12 per kilowatt-hour (kWh). The cost reductions stem from improvements in efficiency, economies of scale, and technological advancements.


In the U.S., module prices remained near historic lows in 2024 at around $0.10 per watt (Wdc) despite a 1% price increase in Q3 due to ongoing overcapacity. However, domestic module prices are still significantly higher than the global average, with U.S. modules selling at a 190% premium over global prices in Q2 2024.


Energy Storage and Hybrid Projects


A major trend in the solar industry is the growing integration of energy storage. The U.S. installed 14.1 GWh of energy storage in the first half of 2024, marking its largest first half on record. Hybrid projects, where solar farms are paired with battery energy storage systems (BESS), are gaining momentum. In 2023, approximately 45% of battery capacity and 26% of utility-scale PV capacity were hybrid systems. This trend is expected to continue as grid reliability becomes a priority​.


U.S. Solar Manufacturing and Policy Support


The passage of the Inflation Reduction Act (IRA) has provided a significant boost to U.S. solar manufacturing, with over 95 GW of new manufacturing capacity added across the solar supply chain. This includes 42 GW of new module production capacity, helping to strengthen domestic supply chains and reduce reliance on imports.


Additionally, new tax incentives for domestic solar ingot and wafer producers will support U.S.-based manufacturing efforts, making it more competitive against imports from Southeast Asia. However, challenges remain as countervailing duties ranging from 0% to 300% have been imposed on crystalline silicon (c-Si) modules and cells from Vietnam, Malaysia, Thailand, and Cambodia.



Solar energy remains at the forefront of the global energy transition, with record-setting capacity additions, falling costs, and supportive policies driving the sector forward. As the U.S. accelerates its renewable energy deployment, challenges related to pricing, supply chain disruptions, and policy uncertainty will need to be addressed. Nevertheless, the outlook for 2025 and beyond is overwhelmingly positive, as solar energy continues to play a crucial role in a cleaner, more sustainable energy future.
