U.S. solar equipment inventories expanded by 126% during the second quarter of 2026 as project developers accelerated procurement to clear a series of federal trade cutoffs. 

Developers across the country are working to reconcile overlapping federal policies with distinct regulatory objectives. The industry spent the summer navigating the July 4 construction-start deadline, the July 24 tariff transition, Foreign Entity of Concern restrictions, and Federal Communications Commission rules regarding inverter components. Attention has now turned toward Dec. 4, when new Section 232 measures take effect for polysilicon, wafers, cells, and modules. 

For utility-scale solar and energy storage developers, operating in this environment requires restructuring multi-party contracts and building operational flexibility into project financing rather than speculating on spot market prices. 

Sabah Bayatli, chief executive officer of San Antonio-based developer OCI Energy, said the market spent late summer and early autumn focused on how Section 232 will dictate post-December pricing dynamics. 

Under the Section 232 proclamation, minimum import price thresholds sit at $0.22 per watt for solar cells and $0.38 per watt for finished solar modules. 

“Without further guidance from the government, it is hard for the market to price solar modules today, because there are two scenarios for modules post-December 4,” Bayatli told pv magazine USA. “It comes down to whether a manufacturer who imports cells from outside the country is able to sell finished panels for less than 38 cents.” 

In addition to price floor interpretations, developers are awaiting administrative guidance from federal trade agencies. S. Customs and Border Protection and the Department of Commerce are expected to issue procedural instructions detailing the self-certification forms importers must execute to clear shipments at entry ports after the deadline.
