AI-Powered supplier vetting

SummaryQingdao Panshen Metal Co., Ltd. is identified as a Chinese manufacturer/factory offering solar panels, solar power systems, vehicle solar charging systems, solar cells, batteries, and related components. The investigation indicates five production lines, stated solar-panel output of 1,000,000 units, and broad export-market coverage. However, the records also show only two employees in general information, no available SDK, no written corrective/preventive-action procedures, zero quality-control test equipment, and no overseas warehouse or showroom. Financial records are indicated for 2023–2025, but no assessable financial results are provided. Certification, customization experience, and customer cases are not documented.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and a limited company based in Qingdao, Shandong, China. Its stated product scope centers on solar panels, solar systems, cells, batteries, and related components.

After-Sales capabilityService controls are weakly documented: there are no written corrective and preventive-action procedures or records, complaint handling has a procedure but no written records, and supplier-service assessment lacks written procedures and followed records. Inventory capability is stated, but there is no overseas warehouse or showroom.

R&D capabilityThe supplier offers a range of solar products, but the stated R&D capability specifically indicates no available SDK. No other measurable R&D, patent, engineering, or product-development evidence is provided.

Production capacityThe supplier states five production lines, solar-panel output of 1,000,000 units, inventory capability, and lead times within 15 working days in both peak and off-season. However, a valid manufacturing-capacity contract is not confirmed, and the general-information record lists only two employees, creating an unresolved capacity-data inconsistency.

Q:How many solar panels do I need for my home?

An average home needs between 17 and 21 solar panels to fully offset utility bills. The exact number depends on your geographic location and individual panel specifications.

Q:Do solar panels work on cloudy days?

Yes, photovoltaic panels can use direct or indirect sunlight to generate power. They remain effective even when light is reflected or partially blocked by clouds, and rain helps keep them clean.

Q:How long do solar panels last?

Solar panels are designed to last more than 25 years. Many panels installed in the 1980s are still working at expected capacity, showing remarkable reliability and increased longevity.

Q:What certifications do your solar panels have?

Our solar panels are certified by EST, ISO, CB, and CE, ensuring they meet international quality and safety standards.

Q:Can I customize the solar panels?

Yes, we offer customized colors, OEM services, and specific connector types. Customization from designs and samples is also available.
