AI-Powered supplier vetting

SummaryYangzhou Intelligence Solar Group Co., Ltd. is a China-based limited company established in 2015, operating from Yangzhou, Jiangsu. It is identified as a factory with a 7,000 m² manufacturing plant, five production lines, 73 employees, and product coverage spanning solar panels, solar systems, batteries, and inverters. Reported output includes 262,800 solar modules, 120,000 all-in-one solar street lights, 120,000 solar power systems, and 139,000 lithium or solar battery sets. The supplier exports to multiple global regions and reports an off-peak lead time within 15 working days. Management-system certification is listed as NIL. Evidence is insufficient to assess after-sales service, customization, and customer cases. The representative-title entry is inappropriate and does not provide usable management information.

Supplier typeThe supplier is explicitly identified as a factory and a limited company, with a 7,000 m² manufacturing plant. Its listed products and manufacturing activities are concentrated in solar energy, lighting, batteries, and related electrical products.

CertificationsThe supplier’s management-system certification is explicitly recorded as NIL. This indicates no management-system certification is evidenced in the provided information.

R&D capabilityThe supplier offers multiple solar and energy-storage products, including lithium batteries, solar systems, inverters, and all-in-one solar street lights. It also reports 10 years of total R&D engineer experience, which supports relevant technical capability, but no patents, new-product record, or dedicated R&D investment is provided.

Production capacityProduction capability is supported by a 7,000 m² plant, five production lines, stated annual outputs across solar modules, energy systems, street lights, power systems, and batteries, and an off-peak lead time within 15 working days. These data provide explicit evidence of established manufacturing capacity.
