Section 232 and modules at USD 0.46 per watt in the United States

The U.S. spot price for solar modules has risen to roughly USD 0.46 per watt following the Section 232 action, announced on 6 August 2026 and effective from 4 December 2026, which adds a minimum import price of USD 0.38 per watt for modules and USD 0.22 per watt for cells to a 15% tariff.

The publication does not say who finances the cell capacity that domestic assembly presupposes. The Solar Market Insight report for the second quarter of 2026, from SEIA with Wood Mackenzie, published on 10 June 2026, records that the country has only 3 GW of cell capacity and that the factories under development are not expected to be enough to supply the module assembly lines already installed.

Until that capital is committed, the minimum price of the imported cell is a cost floor, not a transition stage. It enters the initial investment of every project and changes the ratio between equity and debt before the first generation.

What defines the cost of the U.S. module in the coming years is who puts capital into the cell stage, not the tariff on the finished module.
