AI-Powered supplier vetting

SummaryThe supplier is a limited company offering solar modules, photovoltaic modules, solar energy systems, and batteries, with an affiliated company and 30 employees. It reports ISO9001:2015 and ISO14001 management-system certifications, documented procedures for supplier-service assessment, corrective actions, and complaint handling. Its stated production information includes 800,000 solar energy system sets annually and one production line, while another record reports 21–30 quality-control staff. The supplier supports extensive customization, has introduced new products within the past year, provides ODM services, and offers OEM services for well-known brands. It reports one-month lead times in both peak and off-peak seasons and exports to multiple global regions. However, it has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial records are indicated for recent years, but no substantive financial performance details are provided. Customer cases are not...

CertificationsThe supplier reports ISO9001:2015 and ISO14001 management-system certifications. Product compliance is recorded only as “Others,” without naming specific product certifications or standards, so management certification is evidenced but product-certification coverage is incomplete.

R&D capabilityThe supplier reports that it introduced new products during the past year and provides ODM services. It has no available SDK, but SDK availability is not necessary evidence for general product innovation, so the documented new-product activity supports this capability.

Production capacityThe supplier reports annual output of 800,000 solar energy system sets, one production line, and a one-month lead time in both peak and off-peak seasons. It also reports 21–30 quality-control staff in one record, while another lists four quality assurance and control inspectors; the differing counts create some workforce-data inconsistency, but production volume and lead-time information are explicitly provided.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and design-service records, demonstrating broad customization coverage.

Product Q&A

Q:What is the difference between Tier 1 and non-Tier 1 solar panels?

The main difference is the price. Tier 1 panels often have stock availability for mainstream sizes like 166mm, 182mm, or 210mm, offering lower prices. Customized orders for specific cell types (IBC, P-perc, N-I-TOPCON) or sizes are also available.

Q:How do I choose the best solar panel for my project?

Compare features, performance, and warranty. Residential projects suit 310-410W panels, while commercial or ground mount projects benefit from 400-670W panels. Consider cell size, efficiency, and warranty length.

Q:What are your payment terms?

We accept T/T, L/C, Paypal, Western Union, and other standard payment methods.

Q:What are the advantages of your company?

We are a factory that cooperates with major brands like Longi, JA Solar, Jinko, and Trina, offering better prices and more choices. We provide stable OEM and ODM services.

Q:Can I get a sample to check the quality?

Yes, you are welcome to place a testing order to check the quality before placing a bulk order.
