V. Key Selection Criteria
1. Production capacity (5/100/200 MW; Source: SpecForge); 2. Certifications (IEC 61215/61730/CE; Source: SpecForge); 3. Manufacturing processes (stringing/lamination/testing); 4. Cell specifications (182–230 mm); 5. Automation level (semi-automated/fully automated)—Selection approach: Capacity + Certification + Process (prioritize layout planning).
VI.
Supplier Evaluation
1. Client base (leading global enterprises); 2. Full-line capability (turnkey solutions); 3. In-house R&D (laminators/stringers); 4. Export capabilities (overseas delivery experience);
5. After-sales support (local service)—Evaluation criteria: Clients + Full-line capability + Export capabilities (verify capacity and yield rates).
VII. Procurement Recommendations
1. Large-scale bases: Choose Lead (unmanned workshops); 2. Module lines: Choose Jinchen (laminators); 3. Stringing: Choose Autowell (market leader); 4. Overseas plant construction: Choose Ooitech (turnkey solutions);
5. Acceptance testing: (IEC certification + cycle time)—PV module lines: Autowell (stringing), Jinchen (full-line solutions), Lead (smart factories) (focus on the three key elements: capacity, certification, and process).
