Summary
The US solar manufacturing sector is undergoing a significant supply chain reconfiguration due to tariffs and foreign entity of concern (FEOC) rules implemented under the Trump administration. This shift aims to reduce reliance on Chinese imports, which dominate over 80% of global clean manufacturing. As of early 2026, US solar module manufacturing capacity has increased to 65GW, surpassing domestic demand of approximately 40GW. However, the US still imported 32GW of solar modules last year, indicating that the country is not yet self-sufficient. Upstream manufacturing bottlenecks exist, with cell capacity at only 3.2GW and wafer and ingot capacities at 5GW each. The reliance on imported components poses risks, as tariffs and FEOC restrictions could disrupt supply chains. Developers are encouraged to form partnerships and pursue vertical integration to ensure long-term resilience. The current landscape shows that while progress is being made, the US solar industry remains vulnerable to price competitiveness and sourcing challenges. Key Points: • US solar manufacturing capacity reached 65GW, but 32GW were still imported in 2025. • Tariffs and FEOC rules are reshaping the solar supply chain, increasing costs for developers. • Long-term solutions require partnerships and technological innovation to reduce reliance on China.
