US Solar Cell Imports Decline As Trade Policies Reshape Global Supply Chains

U.S. solar cell imports dropped sharply in the first half of 2026, reflecting major changes in trade policies, domestic manufacturing expansion and global photovoltaic supply chain adjustments.

According to U.S. customs data, the country imported 8.19GW of solar cells from January to June 2026, down 49% compared with 16.18GW during the same period in 2025.

Import Demand Weakens Under Policy and Market Pressure

U.S. solar cell imports experienced rapid growth from early 2024 to mid-2025, reaching a record monthly level of 3.52GW in June 2025.

However, imports declined significantly after the second half of 2025. The slowdown has been driven by stricter trade measures, increasing domestic solar manufacturing capacity, and efforts by companies to reduce inventories.

The decline indicates that the U.S. solar market is entering a new phase, with greater emphasis on localized production and supply chain control.

Supplier Landscape Becomes More Diverse

During the first half of 2026, the top suppliers of solar cells to the U.S. market were:

• South Korea: 2.60GW

• Thailand: 1.63GW

• Ethiopia: 1.06GW

• Malaysia: 785MW

• Kenya: 468MW

Compared with previous years, when Southeast Asian countries dominated U.S. solar imports, supply sources are becoming increasingly diversified.

As trade restrictions expanded on several traditional manufacturing hubs, emerging markets such as Ethiopia, the Philippines and Nigeria began increasing their presence in the U.S. solar supply chain.

New Tariffs May Further Reshape Solar Trade

The U.S. government continues to strengthen trade controls on imported solar products. Under the latest Section 232 measures targeting polysilicon-related products, imported wafers, solar cells and modules containing polysilicon will face a 15% tariff, scheduled to take effect in December 2026.

These policies are expected to encourage more companies to establish localized production and adjust global manufacturing strategies.

Global Solar Industry Moves Toward Supply Chain Diversification

The decline in U.S. solar cell imports does not necessarily indicate weaker solar demand. Instead, it reflects a structural shift in how solar products are manufactured and traded.

As the U.S. continues promoting domestic production and reducing dependence on concentrated supply chains, global solar manufacturers are increasingly exploring new production locations, regional partnerships and diversified export strategies.
