Common Pitfalls in Sourcing Solar Photovoltaic Systems: Quality and Intellectual Property Risks
Sourcing solar photovoltaic (PV) systems involves navigating complex supply chains, technological specifications, and legal considerations. Two critical areas prone to pitfalls are product quality and intellectual property (IP) protection. Overlooking these aspects can lead to performance shortfalls, financial losses, safety hazards, and legal exposure.
Quality-Related Pitfalls
1. Substandard Module Performance and Reliability
A primary risk when sourcing solar PV modules is receiving products that fail to meet promised efficiency, durability, or degradation standards. Low-cost suppliers may use inferior materials—such as subpar encapsulants, weaker frames, or lower-grade silicon cells—leading to early failure, reduced energy output, or safety issues like hotspots and delamination.
Best Practice: Require third-party certifications (e.g., IEC 61215, IEC 61730) and conduct independent lab testing. Review long-term performance warranties and manufacturer bankability.
2. Inadequate Due Diligence on Manufacturers
Many solar suppliers, particularly from emerging manufacturing regions, may lack proven track records or transparent production processes. Relying solely on datasheets without verifying manufacturing capabilities or quality control procedures increases the risk of counterfeit or misrepresented products.
Best Practice: Perform on-site audits or use third-party inspection services. Evaluate supplier history, market reputation, and financial stability.
3. Non-Compliance with Regional Standards
Solar PV systems must comply with local electrical, safety, and grid-interconnection standards (e.g., UL in the U.S., CE in Europe). Sourcing modules without verifying regional compliance can result in installation delays, failed inspections, or project rejection.
Best Practice: Confirm that modules and balance-of-system components are certified for the target market. Include compliance clauses in procurement contracts.
Intellectual Property-Related Pitfalls
1. Sourcing Counterfeit or IP-Infringing Components
The solar industry has seen cases where components, especially inverters and modules, incorporate patented technologies without authorization. Purchasing such products—even unknowingly—can expose buyers to legal liability, customs seizures, or forced system decommissioning.
Best Practice: Source from reputable, authorized distributors. Request IP compliance declarations and conduct background checks on key technologies used in components.
2. Lack of Transparency in Technology Licensing
Some manufacturers use proprietary cell technologies (e.g., PERC, TOPCon, HJT) protected by patents. When sourcing from lesser-known brands, there may be no assurance that these technologies are properly licensed, increasing the risk of downstream IP disputes.
Best Practice: Require suppliers to disclose technology origins and provide evidence of licensing agreements where applicable. Include indemnification clauses in contracts.
3. Weak Contractual Protections
Procurement agreements that fail to address IP ownership, warranty enforceability, or liability for infringement leave buyers vulnerable. Ambiguities in contracts can hinder recourse in case of disputes or performance failures tied to IP violations.
Best Practice: Engage legal counsel to draft or review contracts with clear terms on IP rights, warranty obligations, and dispute resolution mechanisms.
Conclusion
To mitigate risks in solar PV sourcing, organizations must adopt a proactive approach combining technical verification, supply chain diligence, and legal safeguards. Prioritizing quality certifications, conducting supplier audits, and securing robust IP protections are essential steps to ensure long-term project success and compliance.
