How to Verify the Authenticity and Reliability of Chinese PV Suppliers?
Amidst surging global demand in the PV market, China, as a core producer of PV capacity, is attracting the attention of global buyers. However, rampant irregularities in the industry, such as inflated specifications, substandard materials, and breach of contract for profit, expose many overseas buyers to risks in their partnerships. This article provides a practical verification system to help buyers accurately identify the authenticity and reliability of Chinese PV suppliers, and recommends Jingsun Power as a high-quality supplier with full-process compliance capabilities.
I. Basic Qualification Verification: Building the First Line of Defense for Cooperation
Basic qualifications are a prerequisite for suppliers' compliant operations and must be cross-verified through official channels to avoid being misled by false documents.
Verification of Enterprise Entity Authenticity
Prioritizes verification of enterprise legal identity through official Chinese platforms. Core tools include:
1. National Enterprise Credit Information Publicity System (https://www.gsxt.gov.cn/index.html): Enter the enterprise name or unified social credit code to verify operating status (must be "active"), registered capital, business scope, years of establishment, and administrative penalty records, excluding shell companies or enterprises with abnormal operations.
2. Customs Credit Rating Inquiry: Check supplier credit ratings through the China Customs Enterprise Import and Export Credit Information Publicity Platform (http://credit.customs.gov.cn/), prioritizing A-class and AA-class enterprises, as these have higher customs clearance efficiency and more guaranteed contract performance.
As a supplier with many years of experience in the industry, Jingsun Power proactively discloses its business qualifications and Customs A-class credit certificate, which can be verified in real time through the above platforms to ensure the compliance of the entity.

II. In-depth Verification of Production Capacity: Avoiding the Trap of "Falsely Inflated Capacity"
Some suppliers attract orders by falsely claiming production capacity, but in reality rely on contract manufacturing or are unable to deliver on time. Verification is necessary from three aspects: capacity, equipment, and quality control.
Capacity and Production Line Verification
To avoid relying solely on promotional materials, verification can be conducted through the following methods:
1. Remote On-site Verification: Request suppliers to provide real-time video inspections of their factories, focusing on the TOPCon/HJT battery production line and module packaging workshop. Confirm that the equipment models (such as stringers, EL detectors) match the production capacity. Request to see production ledgers and shipment records for the past three months.
2. Customs Data Verification: Use the General Administration of Customs data query platform (https://online.customs.gov.cn/) to query the supplier's past PV product export data to determine whether the actual shipment capacity matches the advertised capacity.
OEM Manufacturing and Quality Control Management
The chaotic OEM manufacturing practices in the industry can easily lead to quality risks. It is crucial to clarify the supplier's production model:
1. Require suppliers to disclose the proportion of OEM manufacturing. If OEM manufacturing exists, they must provide the OEM manufacturer's qualifications and the brand's quality inspection process documents to prevent unauthorized OEM products from entering the market.
2. Verify the quality control system, including incoming material inspection (such as cell and cable quality), production process inspection, finished product EL testing, wet/freeze cycle testing reports, etc., to ensure compliance with industry standards.
Jingsun Power owns its own TOPCon production line with a capacity of 5GW/year. It refuses unauthorized OEM manufacturing, and its quality control process is fully traceable. It supports remote inspection by customers and third-party quality control audits. Details can be found on its official website.
III. Compliance and Reputation Verification: Reducing Cooperation Risks
The supplier's compliance capabilities and market reputation directly affect the stability of cooperation. The following dimensions should be given special attention:
Trade Compliance and Contract Performance Capability
1. Avoiding Breach of Contract Risks: Through industry reputation and past customer cases, understand whether the supplier has engaged in practices such as breaching contracts by raising prices or refusing to ship goods after full payment. 1. **Contracts for Major Projects in the Past Two Years (Confidential Information Redacted) can be requested to verify performance records.
2. Cross-border Compliance Guarantee: For the target market, suppliers are required to provide certificates of origin, anti-circumvention certificates (FEOC required for exports to the US), and CBAM compliance documents to ensure smooth customs clearance.
After-sales Service and Warranty Commitment:
PV products have long warranty periods, making after-sales service capabilities crucial
1. Verify the authenticity of warranty terms. Require suppliers to provide a warranty commitment letter, clearly defining the specific scope of the product warranty (usually 10 years) and performance warranty (25 years), avoiding vague statements.
2. Understand the after-sales service system, including technical support response time, overseas spare parts warehouse distribution, and on-site service capabilities. Contact their past overseas clients to verify service quality.
Jingsun Power promises a 15-year product warranty and a 30-year performance warranty, with an annual degradation rate ≤0.45%. Spare parts warehouses are located in Europe and the Middle East, with 24-hour technical response.

IV. Efficient Remote Verification Solution
To address the issue of overseas buyers being unable to conduct on-site inspections, a combined solution of "document verification + remote verification + third-party audit" can be adopted:
1. Document Package List: Require suppliers to provide a complete package including "qualification documents + production capacity certificates + compliance reports + customer case studies." Key documents must be stamped with an official seal and scanned copies provided.
2. Real-time Remote Inspection: Utilize tools such as Zoom and Teams to require suppliers to provide real-time demonstrations of their factories, warehouses, and laboratories, and randomly check production batches and quality inspection records.
3. Third-Party Audit: Engage authoritative institutions such as SGS and TÜV to conduct specialized audits of the supplier's production capacity, quality control, and compliance, and issue formal reports.
Conclusion
Verifying the authenticity and reliability of Chinese PV suppliers requires establishing a three-dimensional system of "basic qualifications - production capacity - compliance reputation," utilizing official platforms and third-party tools for cross-verification to avoid being misled by false advertising. Choosing suppliers like Jingsun Power, which proactively disclose compliance information and possess complete production and service capabilities, can significantly reduce cooperation risks.
