Solar Manufacturing in the U.S. Now Capable of Meeting All of Domestic Demand

‍

Believe it or not, 2026 is set to be a banner year for solar in the United States. While policy chaos and a coordinated campaign against renewables has led to substantial drawdowns in the clean energy industry, including cancellations of several major solar and wind projects, don't assume U.S. solar is officially down for the count.

In fact, the industry is now better positioned than it's ever been to spring back and capture demand. Thanks to dramatic upscaling of domestic manufacturing capabilities, the U.S. can now boast that it is able to construct every major component that can be found in a fully-assembled array. In addition, its assembly plants can now produce enough modules to meet 100% of domestic demand.

Even in the face of an uncertain political and economic climate, these developments offer a promising look at what's happening on the ground — and what could soon be ahead.

A Rundown of Major Factory Projects, Completed and in the Works

There's been a whirlwind of construction, investing, and development in the solar manufacturing industry. Here's a quick overview of how capacity has changed in recent months, along with what we can expect in the near-future:

$34.8 billion invested since 2022

The Inflation Reduction Act included many policies and provisions to directly boost the solar industry. It worked. Manufacturing capacity quadrupled, and investments came flowing in. 

$34.8 billion, in total, in fact. That's as of December 2025, per the Solar Energy Industries Association (SEIA). $14.3 billion of that (41%) went into facilities now operational. $11.2 billion represents facilities actively under construction, with the remaining $6.1 billion going into projects still in development.

In terms of actual locations, 127 factories are now fully online and producing panels or components. 40 more are currently being built.

The total module building capacity is enough to supply 64.8 gigawatts (GW), which could satisfy the entire current demand for solar in the U.S.

Components-Production Capacity Is Uneven, But Set to Improve

Another milestone hit in recent years is that the U.S. can now domestically produce every component along the finished module supply chain. This hasn't been the case since a company known as SolarWorld shut down in 2013.

Unfortunately, the capacity to produce elements along this supply chain is very uneven. Photovoltaic (PV) cell production is currently bottlenecked, with U.S. manufacturers only able to produce enough to supply roughly 3.2GW in total.

In December 2025, however, ground broke on a new facility in Texas, operated by a new company: T1 energy. It'll increase domestic cell production capacity by 2.1GW. A second phase has been planned to produce an additional 3.2GW, should demand rise to meet the occasion.

Another company, Qcells (a subsidiary of the Korean company Hanwha), is set to open a factory in Crawfordville, Georgia that's capable of producing ingots, wafers, and cells. Two Qcells facilities in Georgia are already producing finished modules, including one at the same site as the new Crawfordville factory.

There's also the maverick of the sector: First Solar. Rather than using silicon, it uses alternative technology it's capable of producing across a range of manufacturing facilities located mainly in the Southeastern U.S. In total, First Solar's facilities represent a vertically integrated supply chain with the ability to produce 14GW of capacity.

Another large-scale player, Corning, has stepped up to increase domestic wafer manufacturing capacity. The company intends to supply up to 15% of the total U.S. wafer market, using excess polysilicon production spun off from its semiconductor manufacturing operation in Michigan. It already has agreements with T1 and another Georgia-based operation, Suniva, to supply raw materials for cells.

All told, limitations in ingot and wafer production constrain the total energy-producing capacity of an all-U.S. supply chain to just 8.3GW. But with modules-producing facilities capable of producing up to 90.1GW in just a few years, demand for components is likely to go up.

Resilience and Self-Reliance Consistent Themes Across Administrations

The U.S. has also upped its capacity to produce other key clean energy components. Our output of domestic inverters, used to convert solar energy and battery storage sources to AC power for grids, has increased 50% in just one year. The manufacturing capacity for building mounting systems has also grown by 14% since 2024.

Surprisingly, one major motivation for onshoring supply chains came not from a U.S. president but from COVID. Supply chain crises in 2020 meant that factories and suppliers had to sit dormant while waiting on materials.

“We learned a lot as an economy during the pandemic, when supply chains were tested,” Scott Moskowitz, vice president of market strategy and public affairs at manufacturer Qcells, told Utility Dive. “We learned that no industry, and particularly a critical industry like energy, wants to be dependent on imported products if they don’t have to be.”
