In 2023, the United States produced about 7.2 GW of PV modules. Since IRA’s passage, over 70 GW of manufacturing capacity has been added across the solar supply chain (from facilities announced pre- and post-IRA), including more than 25 GW of new module capacity.
Since 2005 when Congress passed the investment tax credit, the number of annually installed residential PV systems has grown by approximately 36% per year, or over 250X. At the end of 2023, SEIA estimates there were approximately 4.7 million residential PV systems in the United States.
The United States installed approximately 26.0 GWh / 8.8 GWac of energy storage onto the electric grid in 2023, up 34% y/y. list of acronyms and reviations is available at the end of the presentation. The median system price of large-scale utility-owned PV systems in 2023 was $1.27/Wac—relatively flat since 2018.
The US solar module manufacturing industry experienced record growth in 2024. Domestic module manufacturing capacity grew 190% year-over-year, from 14.5 GW at the end of 2023 to 42.1 GW at the end of 2024. This figure has grown to over 50 GW in early 2025.
After experiencing significant growth in 2023, imports from South Korea and India have slowed, although they still collectively accounted for 15% of module imports in 2023 and 8% of imports in Q1 2024. Looking historically, import levels had decreased after the withhold release order (WRO) on PV cells and modules was announced in late Q2 2021.
The median price for residential PV systems reported by EnergySage increased 6.3% y/y to $2.8/Wdc—in-line with mid-2020 price levels. Global polysilicon spot prices fell 22% from mid-January ($8.70/kg) to late April ($6.76/kg), approaching the lowest nominal price seen over the past decade.

The global commercial and industrial solar energy storage battery market is experiencing unprecedented growth, with demand increasing by over 400% in the past three years. Large-scale battery storage solutions now account for approximately 45% of all new commercial solar installations worldwide. North America leads with a 42% market share, driven by corporate sustainability goals and federal investment tax credits that reduce total system costs by 30-35%. Europe follows with a 35% market share, where standardized industrial storage designs have cut installation timelines by 60% compared to custom solutions. Asia-Pacific represents the fastest-growing region at a 50% CAGR, with manufacturing innovations reducing system prices by 20% annually. Emerging markets are adopting commercial storage for peak shaving and energy cost reduction, with typical payback periods of 3-6 years. Modern industrial installations now feature integrated systems with 50kWh to multi-megawatt capacity at costs below $500/kWh for complete energy solutions.
Technological advancements are dramatically improving solar energy storage battery performance while reducing costs for commercial applications. Next-generation battery management systems maintain optimal performance with 50% less energy loss, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $1,000/kW to $550/kW since 2022. Smart integration features now allow industrial systems to operate as virtual power plants, increasing business savings by 40% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 30% for commercial storage installations. New modular designs enable capacity expansion through simple battery additions at just $450/kWh for incremental storage. These innovations have significantly improved ROI, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (50-100kWh) starting at $25,000 and premium systems (200-500kWh) from $100,000, with flexible financing options available for businesses.
