AI-Powered supplier vetting

SummaryWHC SOLAR is a Guangdong-based solar and new-energy supplier with a stated business scope covering photovoltaic equipment, batteries, new-energy equipment, lighting, and related technology research. It provides OEM and ODM services, supports multiple customization modes, and reports new products within the past year. Its operational evidence includes five production lines, 6–10 quality-control staff, stated inspection instructions, inventory capability, overseas warehouses and showrooms, and valid manufacturing contracts with associated subcontractors. The supplier reports quality-assurance procedures, complaint-handling and corrective-action procedures with records, and overseas installation, repair, maintenance, debugging, and training services. However, the provided information does not establish specific certifications, named customer cases, or financial performance; export information is strong, with 90% of sales reportedly from exports and self-operated import/export rights.

Supplier typeThe supplier is presented as WHC SOLAR, headquartered in Guangzhou, Guangdong, with business activities spanning solar power technology services, photovoltaic equipment and component sales, batteries, new-energy equipment, lighting, and related engineering and technology research. This supports classification as a solar and new-energy equipment supplier rather than a narrowly specialized trading entity.

After-Sales capabilityThe supplier reports clear, followed procedures for customer complaints and corrective/preventive actions, plus overseas installation, repair, maintenance, debugging, and training services. Overseas warehouses, showrooms, and inventory capability further support service delivery, although the countries covered by overseas services are confidential.

R&D capabilityThe supplier reports that it had new products during the past year and identifies engineering, technology research, and new-material technology research activities in its business scope. It also offers ODM services, although it reports no available SDK; the evidence supports product-development activity but does not establish the depth of its innovation infrastructure.

Production capacityProduction-related evidence includes five production lines, 6–10 quality-control staff, stated annual output of 3,000,000 sets for WHC Solar System, inventory capability, valid contracts with associated subcontractors, and documented finished-product inspection instructions. Reported order fulfillment takes 2–3 months in off-peak periods and 6–12 months in peak periods, indicating capacity exists but peak lead times are extended.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM services and OEM services for well-known brands, providing direct evidence of broad customization and contract-manufacturing capability.
