Solar coverage almost always points at the field. Two million panels going up on a Texas coal mine, ninety-six of them floating on an Arkansas rice pond, and the number everybody prints is acreage or megawatts.
The building the panels came out of gets a clause in the eleventh paragraph, if it gets anything at all.
In Iberia Parish, Louisiana, the building is the whole story. First Solar’s plant on the grounds of the Acadiana Regional Airport covers roughly 2.4 million square feet and cost about $1.1 billion.
It takes a raw sheet of glass in one end and hands out a finished solar module roughly four and a half hours later. At full rate it is supposed to produce a dozen panels a minute.
The plant has been making them since July 2025 and got its ribbon cut in November. What changed in August 2026 is a document signed on the 6th.
It drops a hard price floor under every imported solar module in the country starting December 4. Louisiana is one of the very few plants in America with no reason to care.
First Solar leans on one comparison for the scale of this place: about 11 times the size of the New Orleans Superdome. Louisiana Economic Development repeated it in the inauguration release, and so did almost everyone who covered the opening.
Work backwards and 11 turns out to be the polite middle of a very wide range. A multiple of 11 against 2.4 million square feet implies a Superdome of roughly 218,000 square feet, which is not a figure the stadium publishes anywhere.

The main floor is about 166,180 square feet. Measured that way the factory is closer to 14 stadiums.
The dome’s steel frame covers 13 acres, or roughly 566,000 square feet, which drops the multiple to about four. And Trahan Architects, which has handled the Superdome’s renovations since 2005, describes it as a 2,000,000-square-foot stadium. By that yardstick the factory wins by about 20 percent.
None of those numbers are wrong. They measure different things, which is the permanent problem with stadium comparisons.
The honest version is that the plant lands somewhere between slightly bigger than the Superdome and fourteen times its playing surface. It is an absurdly large building whichever end of that you pick.
Vertically integrated gets thrown around loosely. Here it means the plant receives sheet glass and ships a complete Series 7 module, with the cadmium telluride semiconductor deposited on site instead of bought in as a finished cell.
The line is designed to do that in about four and a half hours. Fully ramped, the site adds 3.5 gigawatts of annual nameplate capacity.
The dozen-a-minute claim holds up under arithmetic, incidentally. Three and a half gigawatts a year at Series 7 wattages works out to roughly 12 modules every 60 seconds if the line never stops, which it is not meant to.
The materials list is the part worth reading twice. Glass from Illinois and Ohio. Steel from Mississippi, fabricated into back rails in Louisiana.
Series 7 skips the anodized aluminum frame most panels use and mounts on galvanized steel rails instead. That is also why it is a utility-scale product and not something you put on a roof.
The plant runs computer vision and deep learning to catch module defects during production, which is where the AI-enabled label in the press release comes from. It is quality control, not a robot workforce.
More than 700 people worked there at the ribbon cutting, with 826 targeted by the end of 2025. Average compensation runs around $90,000, more than triple per capita income in the parish.
Louisiana put up $30 million in performance-based grants for site work and infrastructure, on top of its FastStart training program. A University of Louisiana at Lafayette study commissioned by the local development authority forecasts the plant will lift Iberia Parish GDP by 4.4 percent in its first full year at capacity.
Commerce opened a Section 232 national security investigation into polysilicon and its derivatives on July 1, 2025. The proclamation landed on August 6, 2026, and it is considerably heavier than the safeguard tariffs it replaces, which expired back on February 7.
It sets minimum import prices at four levels, and stacks a 15 percent tariff on top of everything except raw polysilicon. All of it applies to goods entering at 12:01 a.m. Eastern on December 4.
The White House said the United States is virtually entirely dependent on imports of solar ingots, wafers and cells. First Solar backed the action publicly the same day, noting that Chinese producers control more than 90 percent of global polysilicon supply, as pv magazine USA reported.
Now look at what that means for Iberia Parish. There is no polysilicon in a cadmium telluride module. No ingot, no wafer, no crystalline silicon cell.
And a panel built in New Iberia is not an import, so the floor never reaches it. The proclamation lifts the cost basis under a large share of the modules sold in this country and walks straight past this factory.
The clean-supply-chain framing is real, and it also has a hole in it that First Solar discloses itself.
In its quarterly filing for the period ended June 30, 2026, the company notes that China’s February 2025 export controls covered products containing tellurium, which it calls one of the main components of its CdTe modules.
Tellurium is sourced globally, the filing says, but China is a major producer, and Chinese exporters generally need a license from the Ministry of Commerce to ship it.
So the Louisiana plant is free of Chinese polysilicon and exposed to Chinese tellurium. Trading one dependency for a much smaller one is a real improvement. It is not the same thing as independence.
The company’s answer is recycling. It has run in-house PV recycling for more than 20 years and reported an average material recovery rate above 95 percent in 2025, pulling tellurium back out of dead modules along with glass, steel and aluminum.
That is a different problem from the one the SOLARCYCLE plant in Cedartown, Georgia is built to solve, since that line is optimized for crystalline silicon panels.
First Solar closed the second quarter with a contracted backlog of 45.1 gigawatts running through 2030, worth roughly $13.6 billion before technology adjusters. About 41 gigawatts of that carries some form of domestic content requirement, which is exactly why a domestic plant commands a premium.
The quarter itself was good and slightly strange. Net sales came in at $1.06 billion, down 4 percent year over year on lower contract-termination revenue.
Net income went the other way: $423 million, or $3.92 per diluted share, up 23 percent. Adjusted EBITDA hit $644 million on a 61 percent margin, and the company passed 100 gigawatts of cumulative module sales globally. Full-year guidance held at 17.0 to 18.2 gigawatts sold.
On the July 30 call, chief executive Mark Widmar named Cypress Creek, Terra-Gen and Panamint as recent deals, about 5 gigawatts combined with roughly half tied to Google.
Panamint is the company putting two million First Solar panels on a working Texas coal mine. That is the loop closing. The plant fills the backlog, and the backlog is the field.
The sixth American plant, in Gaffney, South Carolina, is not another glass-to-module operation. It is a finishing facility, up to 3.5 gigawatts of capacity for modules started at the company’s international sites.
Phase one begins production in the second half of 2026. Phase two now lands mid-2027, pushed back to fold in the CuRe efficiency upgrade earlier.
First Solar went from roughly 6 gigawatts of US nameplate capacity in 2020 to about 13 in 2025, and expects more than 17 by 2027 with all six domestic plants ramped.
That last number has been drifting quietly. In November 2025 it was 17.7 gigawatts. In the August 6 statement it became approximately 17.
Which leaves Iberia Parish in an odd spot for a building that opened nine months ago. It is finished, staffed and running, and the policy that makes its economics obvious does not bite for another three and a half months.
The semiconductor inside its panels still needs a Chinese export license to leave China. Eleven Superdomes of floor turned out to be the easy part.
Don’t bite your tongue. Speak up.
