AI-Powered supplier vetting

SummaryShenzhen Hopesun Solar Technology Co., Ltd. is identified as a Chinese manufacturer/factory established in 2011, producing a broad range of solar panels, chargers, lighting products, and solar systems. The supplier reports ISO 9000 and ISO 9001 management-system certifications, 21–30 years of combined R&D-engineer experience, a 5,000-square-meter factory, more than 160 employees, 50 quality-control staff, and seven production lines. Its stated export coverage is broad, spanning multiple regions, and its factory is located near Shenzhen and Hong Kong ports. Evidence supports established manufacturing, quality-management, and R&D capabilities. However, after-sales processes, financial credibility, customization capability, and the depth of customer references are not sufficiently documented. One trade record identifies a Mexican buyer and one transaction, but this is limited evidence rather than a broad customer-case history.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and operates under the legal name Shenzhen Hopesun Solar Technology Co., Ltd. It reports a 5,000-square-meter factory in Shenzhen, China, and offers solar panels, chargers, lighting, and solar-system products, supporting its classification as a direct manufacturing supplier.

CertificationsThe supplier reports ISO 9000 and ISO 9001 certification for its management systems. These stated certifications provide explicit evidence of formal quality-management practices, although no certificate numbers, issuing bodies, or validity dates are provided.

R&D capabilityThe supplier reports 21–30 years of total R&D-engineer experience, states that R&D is a priority, and says it invests 8%–10% of sales revenue annually in R&D. Its product range includes flexible, foldable, glass, balcony, and other solar solutions, providing explicit evidence of active product-development capability.

Production capacityThe supplier reports a 5,000-square-meter factory, more than 160 employees, 50 quality-control staff, seven production lines, and stated annual output for solar systems and solar panels. Its broad export-market coverage and access to Shenzhen and Hong Kong ports further support operational capacity, although production figures are self-reported and their units are not clarified.
