Despite the significant growth in module manufacturing capacity, the U.S. solar industry still faces dependencies on foreign suppliers for critical components:

• Wafers and Cells: As of September 2024, the U.S. has no operational facilities that can turn raw polysilicon into solar wafers and cells. This gap in the supply chain means that "China still makes most of the U.S.'s solar wafers."
• Polysilicon: While the U.S. has "roughly enough polysilicon capacity to meet its needs," the lack of domestic wafer and cell production means this raw material often must be exported for processing before returning as part of completed solar cells or modules.

2. Efforts to reduce reliance on imports

Several initiatives are underway to address these supply chain gaps:

1. Qcells' Vertical Integration: Hanwha Qcells' planned end-to-end factory in Cartersville, Georgia, is expected to start manufacturing wafers and cells in early 2025, potentially filling a critical gap in the U.S. supply chain.
2. Policy Incentives: The IRA's Advanced Manufacturing Production Credit (AMPC) is designed to incentivize domestic production across the entire solar supply chain, including wafers and cells.
3. Industry Standards: SEIA's introduction of Standard 101, a "first-of-its-kind standard to enhance transparency of the solar and storage supply chain," aims to help companies trace supply chain origins and satisfy customs requirements. This standard, expected to be published and in use by Q1 2025, could facilitate more robust domestic supply chains and reduce reliance on opaque international sourcing.

In conclusion, while the U.S. solar industry has made significant strides in expanding domestic manufacturing capacity, particularly for modules, challenges remain in achieving full supply chain independence. The continued implementation of supportive policies, strategic investments by companies like Hanwha Q Cells, and industry-led initiatives for supply chain transparency are all crucial elements in the ongoing effort to strengthen and secure the U.S. solar industry supply chain.?
