Common Pitfalls When Sourcing Solar Power in the USA: Quality and Intellectual Property Risks

Sourcing solar power solutions in the United States—whether for residential, commercial, or utility-scale projects—can offer significant benefits, but it also comes with key risks related to component quality and intellectual property (IP). Understanding these pitfalls is essential for making informed, secure procurement decisions.

Quality Concerns in Sourced Solar Equipment

One of the most prevalent challenges in the U.S. solar market is ensuring the consistent quality of photovoltaic (PV) modules, inverters, and balance-of-system components, particularly when sourcing from overseas manufacturers or less reputable domestic suppliers.

• Inconsistent Manufacturing Standards: Solar panels sourced from manufacturers with lax quality control may suffer from premature degradation, microcracks, or delamination, reducing performance and lifespan. Panels that do not meet IEC (International Electrotechnical Commission) or UL (Underwriters Laboratories) standards can fail under real-world conditions.

• Counterfeit or Misrepresented Products: Some suppliers may rebrand or relabel lower-tier modules as Tier-1 products, misleading buyers about reliability and bankability. Independent verification through third-party testing (e.g., PVEL’s PV Module Reliability Scorecard) is critical.

• Warranty Limitations and Enforcement: While many panels come with 25-year performance warranties, the financial stability of the manufacturer matters. If a company goes out of business, warranty claims may be unenforceable. Buyers should assess manufacturer longevity and warranty underwriting.

• Inverter Reliability and Compatibility: Inverters are a common point of failure. Sourcing inverters without proper certifications or compatibility with U.S. grid codes (e.g., IEEE 1547) can lead to system downtime and safety hazards.

Intellectual Property and Legal Exposure

Intellectual property issues are increasingly relevant in the solar supply chain, particularly as the U.S. enforces trade policies and protects domestic innovation.

• Patent Infringement Risks: Certain solar technologies, especially in high-efficiency cell designs (e.g., PERC, TOPCon), are protected by patents held by U.S. or international companies. Sourcing panels from manufacturers that use patented technology without licensing can expose buyers or developers to legal action.

• Import Restrictions and UFLPA Enforcement: The Uyghur Forced Labor Prevention Act (UFLPA) presumes that solar products from Xinjiang, China, involve forced labor. Sourcing panels from supply chains with ties to this region—even indirectly—can result in customs holds, seizures, or reputational damage. Buyers must demand full supply chain transparency and traceability.

• ITC and Anti-Dumping Duties: The U.S. International Trade Commission (ITC) has imposed tariffs on solar imports from certain countries to protect domestic manufacturers. Sourcing products that fall under these rulings without proper duty payments can lead to financial penalties.

• Technology Theft and Reverse Engineering: Some foreign manufacturers have been accused of replicating U.S.-developed solar technologies without authorization. Procuring such products—knowingly or not—can indirectly support IP violations and undermine innovation.

Mitigation Strategies

To avoid these pitfalls, stakeholders should:
– Conduct thorough due diligence on suppliers, including factory audits and third-party performance testing.
– Verify component certifications (UL, IEC, IEEE) and ensure compliance with U.S. electrical and building codes.
– Require full supply chain documentation, especially for modules, to comply with UFLPA and customs requirements.
– Consult legal counsel to assess IP risks when adopting new or cutting-edge solar technologies.
– Prioritize suppliers with strong warranties backed by reputable financial institutions.

By proactively addressing quality and IP concerns, solar developers and buyers in the U.S. can reduce project risk, ensure long-term performance, and support a responsible and sustainable solar industry.
