The Section 232 solar module price floor takes effect on December 4, 2026, and it changes the arithmetic behind the timing of a commercial solar purchase. According to PV Magazine's report of September 1, the measures announced on August 6, 2026 set minimum import prices of 38 cents per watt for modules and 22 cents per watt for cells, add a 15% ad valorem tariff on solar imports, and sit on top of the existing Section 301 tariffs of 10 to 12.5%. Module spot prices in the United States have already moved to roughly 46 cents per watt, a level the market last saw in 2023.
That is the cost side, and it is real. The same report carries the half of the story a buyer in Georgia or the Carolinas should read twice. Analysts expect domestic module assembly to take over the market in 2027, and they project that a module assembled in the United States from imported cells could settle near 30 cents per watt once that capacity is running. A floor under imports is also an instruction to build here, and the report expects assembly capacity in this country to follow.
What does a minimum import price actually do?
A minimum import price is a hard bottom, not a percentage. After December 4, an imported module cannot enter the country below 38 cents per watt, whatever the exporter would be willing to accept, and an imported cell cannot enter below 22 cents. Christian Roselund, a policy research manager quoted by PV Magazine, described the practical effect as the effective elimination of module imports, with plain economics steering buyers toward domestically assembled product.
The cell floor is the number to watch. It is what anchors the 30 cent projection: imported cells at their floor, assembled into modules in a US plant, land well below today's 46 cent spot price. The report expects that shift to show during 2027 rather than immediately.
What this means for a facility in the Southeast
Modules are one line in the installed cost of a commercial system. Racking, inverters, conductors, switchgear, structural and electrical engineering, permitting and the utility interconnection are the others, and none of them is priced by this rule. The share that moves is the module share, and it moves in both directions depending on when and what you buy.
The scale is easy to see on a real project. A 500 kW rooftop array uses about 500,000 watts of modules. At today's 46 cents that is roughly $230,000 of panels. At the 30 cents the analysts project for US-assembled product in 2027, the same panels cost about $150,000. That $80,000 gap is why the timing question is worth asking, and why the answer is not simply to wait.
Waiting has a price of its own, and it sits on the tax side. As we set out in our note on the commercial solar tax credit deadline in 2027, a project that begins construction after July 4, 2026 has to be in service by December 31, 2027 to claim the federal credit. A business that delays its module order into late 2027 to catch the lower price can find it has run out of calendar for a credit worth far more than the module saving. The two dates have to be planned together.
There is a second incentive pulling the same way. The 30% federal solar tax credit for businesses carries a bonus of up to 10 percentage points for domestic content. A market that shifts to US assembly makes that content easier to source, though whether a given project qualifies depends on cost-based rules that your accountant applies to the actual bill of materials, and nobody should count the bonus before that work is done.
For a sense of where module cost sits inside the whole, our breakdown of commercial solar cost per kW in Georgia walks through the other lines that a tariff does not touch.
How we handle module procurement on a project
We build under a single commercial solar EPC contract, which means module procurement is our problem inside the project rather than a separate purchase you manage. Pricing is fixed at contract, the supplier's delivery date is written into the schedule, and the country of origin and the cell source are documented at the time of order, because the same paperwork that supports a domestic content claim also answers the foreign entity rules that now apply to the credit.
On the 1.267 MW Samsonite and TUMI roof in Vidalia, the modules were one line inside a contract that also carried the structural engineering, the interconnection package and 55,000 pounds of BatteryCube® storage. That is the scale at which a few cents per watt on the module line matters, and also the scale at which the module line is a minority of the total.
For businesses building commercial solar in Georgia over the next eighteen months, the practical position is this: the floor does not raise today's price, domestic assembly is likely to lower it through 2027, and the federal credit's calendar decides how long you can afford to wait for that to happen.
If you want the two dates worked out against your own roof and your own bill, send us twelve months of utility bills and we will come back with a system size, a procurement window and a schedule that keeps the credit within reach.
