China produces roughly 80% of global solar panels at costs U.S. manufacturers cannot match without government support.1 A June 2026 risk assessment of Tony Etnyre, CEO of U.S. solar cell maker Suniva, identifies this gap as a catastrophic vulnerability: domestic production survives only because Section 201/301 tariffs block cheaper imports and IRA manufacturing tax credits offset the cost difference.1
Remove either pillar, and U.S.-made solar cells cannot compete.1 The assessment rates this risk medium likelihood but catastrophic severity — not a margin squeeze but a structural collapse of the business case for domestic production.
The dynamic mirrors challenges facing solar manufacturers in Europe and India, where domestic-content incentives and import duties have similarly propped up local industries against Chinese competition. But U.S. exposure is acute: Suniva operates in a market where policy continuity is not a growth factor but a precondition for survival.1
IRA manufacturing production credits have functioned as a direct lifeline, compensating for the cost gap that would otherwise make American solar cells uneconomical.1 Section 201 and 301 tariffs simultaneously shield factories from lower-cost foreign supply. Together, they are a survival mechanism, not a competitive advantage.
For global investors and lenders with exposure to U.S. solar manufacturing assets, this creates a distinctive risk category. A new administration reconsidering trade policy, or Congress cutting IRA subsidies in budget negotiations, would not gradually erode margins — it would eliminate the economic rationale for the sector.1
Capital allocation, capacity planning, and long-term contracts at Suniva all carry embedded policy-expiration risk.1 Standard credit and equity models frequently underweight this type of legislative dependency. When a company's cost competitiveness is a policy artifact rather than an operational achievement, the risk belongs in a separate analytical category entirely.
