AI-Powered supplier vetting
SummaryThe supplier demonstrates broad photovoltaic equipment and metal structure manufacturing capabilities, with over 80 production lines, stated daily capacity of 900 tons, annual output exceeding 10GW, and more than 30 patents. It offers flexible customization, ODM services, OEM services for well-known brands, and maintains documented design and quality-control procedures. Certifications include ISO9001, ISO14001, ISO145001, green supply chain recognition, 5-star after-sales service certification, domestic certification for eight bracket product categories, and EU certification. Overseas service is documented for Iran and includes debugging, repair, and training. However, the supplier has only one year of export experience, lacks valid manufacturing contracts with affiliated subcontractors, and has no overseas warehouse or showroom. Evidence of financial strength and specific customer cases is insufficient.
Supplier typeThe supplier’s stated scope includes photovoltaic equipment and component manufacturing, sales, and metal structure manufacturing. Its more than 80 production lines and automated steel-processing capabilities indicate a manufacturer rather than only a trading or service company.
CertificationsThe supplier reports ISO9001, ISO14001, ISO145001, green supply chain recognition, and 5-star after-sales service certification. Eight major bracket product categories have domestic certification, and the products also hold EU certification, providing explicit evidence of substantial certification coverage.

R&D capabilityThe supplier provides ODM services, has more than 30 technical and utility model patents, and uses SolidWorks for R&D. It also maintains auditable design input, output, review, verification, and validation documentation, although no SDK is available.
Production capacityThe supplier reports over 80 production lines, automated forming, cutting, forging, and welding equipment, daily production capacity of 900 tons, and annual output exceeding 10GW. It also reports in-stock capability, but lacks valid contracts with affiliated subcontractors, which limits confidence in outsourced manufacturing arrangements.
