Common Pitfalls Sourcing Solar in the USA (Quality, IP)

When sourcing solar panels and related components in the USA, businesses and project developers often encounter challenges that can impact project performance, compliance, and long-term reliability. Two critical areas of concern are product quality and intellectual property (IP) risks.

Quality Concerns

One of the most significant pitfalls in solar sourcing is inconsistent product quality. While the U.S. market offers a range of domestic and imported solar panels, not all meet the same standards. Key quality-related risks include:

• Inferior Manufacturing Processes: Some imported panels, particularly from regions with less stringent oversight, may use substandard materials such as low-grade encapsulants or frames prone to corrosion, leading to premature degradation.
• Lack of Certification Compliance: Panels must meet UTL (Underwriters Laboratories), IEC (International Electrotechnical Commission), and UL 61730 standards. Sourcing from suppliers who bypass or falsify certifications can result in safety hazards and failed inspections.
• Performance Variability: Panels may underperform relative to their stated wattage or efficiency due to inaccurate binning or poor quality control during manufacturing.
• Warranty Limitations: Some manufacturers offer attractive warranties on paper, but lack a U.S.-based service network, making claims difficult to enforce and support slow or unavailable.

To mitigate these risks, buyers should prioritize suppliers with third-party testing validation, strong track records, and transparent supply chains—ideally those using domestically produced cells or fully integrated U.S. assembly.

Intellectual Property (IP) Risks

Intellectual property infringement is another often-overlooked hazard when sourcing solar technology, particularly imported components:

• Patent Infringement: Several U.S. companies hold patents on key solar technologies, such as cell architectures (e.g., PERC, TOPCon) and module designs. Importing panels that use patented technology without licensing can lead to legal action, shipment seizures by U.S. Customs, or exclusion orders from the International Trade Commission (ITC).
• Recent Trade Enforcement Actions: The U.S. has enforced trade laws like the Uyghur Forced Labor Prevention Act (UFLPA) and antidumping/countervailing duties (AD/CVD) on solar cells and modules from certain regions, especially those tied to forced labor or state-subsidized manufacturing. Sourcing from non-compliant supply chains can expose companies to regulatory penalties and reputational damage.
• Lack of IP Transparency: Some suppliers may not disclose the origin of cells or the technology used, increasing the risk of inadvertently purchasing infringing or blacklisted products.

To avoid IP pitfalls, buyers should conduct thorough due diligence, request documentation on technology licensing and supply chain traceability, and work with suppliers who comply with U.S. trade regulations and respect intellectual property rights.

Addressing both quality and IP concerns is essential for ensuring reliable, legally compliant, and sustainable solar deployments in the U.S. market.
