AI-Powered supplier vetting

The supplier reports multiple management-system certifications, 50 quality-control staff, more than 10 production lines, extensive solar-product output, export activity since 2004, and sales coverage across multiple global regions. It states that it provides product design, R&D, manufacturing, shipment arrangement, warranties, after-sales service, and market suggestions. The available information supports strengths in manufacturing scale, export experience, product development, customization, and stated service capabilities. However, financial credibility cannot be assessed because relevant financial information is excluded, and the representative-title record is invalid or unusable.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, with production locations in Shenzhen, Guangdong, China. Its descriptions identify separate production entities for domestic and overseas business, supporting direct manufacturing involvement rather than a purely trading profile.

CertificationsThe supplier lists BSCI, ISO 9000, ISO 9001, ISO 14001, ISO 14000, HSE, GMP, EICC, and QC 080000 as supplier-management-system certifications. The slice does not provide certificate numbers, validity dates, issuing bodies, or scopes, so the assessment is based on the stated holdings only.

After-Sales capabilityThe supplier explicitly states that it provides a warranty period for each product, after-sale service, and reasonable suggestions for solar products and markets. It also describes support across the full shipment process, indicating a stated service capability beyond production.

R&D capabilityThe supplier states that it designs, researches, develops, and manufactures solar products according to customer requirements, and reports total R&D-engineer experience of 31–40 years. These statements support product-development capability, although they do not quantify patents, laboratories, or new-product launches.

Production capacityThe supplier is identified as a factory and reports more than 10 production lines, 50 quality-control staff, and substantial stated output for solar systems, panels, chargers, and lights. It also lists a broad solar-product portfolio and export coverage across multiple regions, supporting significant production breadth and capacity.

Customization capabilityThe supplier explicitly states that it designs, researches, develops, and manufactures solar products according to customer requirements and supplies products in customers' quality classes. This directly supports customization in product design and quality specifications.

Product Q&A

Q:What is the difference between PET and ETFE covers?

ETFE offers a longer lifespan (15-20 years) and higher light transmittance (90-98%) compared to PET (2-5 years lifespan, 80-85% transmittance). ETFE is also more flexible and lighter, while PET is thicker and more cost-effective.

Q:Can I customize the solar panel size and shape?

Yes, we support OEM and ODM services. Holes, shape, size, DC wire, and USB types are all optional. You can also have your brand logo printed on the gift box and products for free.

Q:What are the warranty terms for the solar panel?

The warranty depends on the cover material: PET cover has a 2-year warranty, while ETFE cover has a 5-year warranty. The product lifespan is over 6 years for standard models and up to 15 years for ETFE.

Q:How long does it take to deliver an order?

Sample orders can be delivered within 3 days. Trial orders take 10-15 days. Mass quantity orders (up to MOQ) take 25-30 days. Peak season lead time is one month, and off-season is within 15 workdays.

Q:What certifications does the product have?

The product is certified by TUV, CE, ROHS, FCC, PSE, IEC61215, IEC61730, SONCAP, and SASO. We also hold ISO 9001:2008 certification.
