VI. Key Factors in Selecting a Manufacturer
Verification: Check for records of corporate dishonesty/credit defaults (Source: Qichacha); Factory Inspection: “Green Factory” certification (Source: Trina); Certifications: TÜV, UL, and CE certificates (Source: Industry standards); Shipments: Shipment volume rankings (Source: Douyin);
After-sales Service: Global service network (Source: Industry standards)—Manufacturer selection: Verification + Factory Inspection + Certification (Three-step check).
VII. Procurement Recommendations
First, choose an industry leader (Trina modules); second, pair with inverters (GoodWe energy storage); third, assess risks (check Qichacha for credit defaults); fourth, source auxiliary materials (Suzhou pastes);
fifth, conduct factory inspections (“Green Factory” status)—Jiangsu manufacturers: Trina + GoodWe + Supporting components (Three-tier approach).
