Supply Chain Analysis & Manufacturing Process
Complete Solar Panel Manufacturing Steps
Understanding the manufacturing process reveals both the complexity and the current gaps in US production:
Step 1: Polysilicon Production – Silicon metal is purified to 99.9999% purity through chemical processes. The US has rebuilt significant capacity in this area, though still imports substantial quantities.
Step 2: Ingot Formation – Polysilicon is melted and formed into cylindrical ingots through the Czochralski process. This remains largely dependent on imports, with limited US production.
Step 3: Wafer Slicing – Ingots are sliced into thin wafers using wire saws. This represents the largest supply chain gap, with virtually no commercial US production currently operational.
Step 4: Cell Processing – Wafers undergo doping, texturing, and metallization to create photovoltaic cells. US cell production is resuming but remains limited compared to demand.
Step 5: Module Assembly – Cells are interconnected, laminated with protective materials, and framed to create finished solar panels. This represents the strongest segment of US manufacturing.
Current Supply Chain Gaps
Despite remarkable progress, significant gaps persist in the US solar supply chain. Wafer production represents the most critical shortage, with announced domestic capacity still years away from meeting demand. Cell production, while improving, remains insufficient to support full domestic module assembly.
These gaps mean that even “Made in USA” panels often contain imported components, particularly wafers and cells from Southeast Asian facilities. However, the economic and strategic value of domestic assembly, combined with growing upstream capacity, provides substantial benefits over fully imported alternatives.
Policy Impact & Government Support
Inflation Reduction Act Manufacturing Incentives
The IRA’s advanced manufacturing tax credit provides up to $7 billion annually in incentives for domestic clean energy manufacturing. Solar manufacturers receive:
- $0.07 per watt for solar modules
- $0.04 per watt for solar cells
- $0.12 per square meter for wafers
- $3 per kilogram for polysilicon
These incentives have directly enabled over $34 billion in announced manufacturing investments, with facilities in Republican-leaning states receiving substantial support, creating bipartisan political backing for continued expansion. However, recent legislative developments may impact these programs, as discussed in our comprehensive guide to federal solar tax credits.
Federal Tax Credits for Manufacturers
Beyond the advanced manufacturing credit, solar manufacturers benefit from additional federal support including accelerated depreciation schedules, investment tax credits for manufacturing equipment, and research and development tax credits for innovation activities.
The CHIPS and Science Act also provides 25% investment tax credits for solar ingot and wafer manufacturing facilities, addressing the most significant supply chain gaps.
