AI-Powered supplier vetting

SummaryRosen Solar Energy Co., Ltd. is identified as a Chinese manufacturer/factory offering solar panels, solar systems, lithium batteries, AGM/GEL batteries, and energy storage systems. The supplier reports broad customization, ODM, SDK availability, recent new-product activity, and OEM service for known brands. Its service procedures include documented assessment, corrective action, and complaint-handling records, although the approved-supplier list lacks approval signatures or dates. Overseas service is reported in Hungary for debugging, equipment installation, and training, but there are no overseas showrooms, agents, branches, or offline trade-show participation. Export sales represent 71%–90% of total sales, and the supplier reports peak- and off-season lead times within 15 working days. Production-scale information is inconsistent: one slice describes a battery factory with 145,000 square meters and more than 1,360 employees, while another lists 20 total employees. No certification information or...

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company in China. Its stated product scope includes solar panels, solar systems, lithium batteries, AGM/GEL batteries, and solar energy storage systems, while it is not reported as part of a larger company group.

After-Sales capabilityThe supplier reports overseas services in Hungary, including debugging, equipment installation, and training. It also has written procedures and followed records for service assessment, corrective and preventive actions, and customer complaint handling; however, it has no overseas showroom, agent, branch, or offline trade-show participation, and its approved-supplier list lacks approval signatures or dates.

R&D capabilityThe supplier reports new-product activity during the past year, ODM service, and an available SDK. Its business scope also explicitly includes R&D and production of solar LED and optical-material products, supporting an active product-development capability.

Production capacityThe supplier states that it manufactures, processes, assembles, sells, and installs related products, and describes battery production across lithium, VRLA AGM, VRLA GEL, OPzS, and OPzV types for multiple applications. Production-scale evidence is inconsistent because one slice reports a 145,000-square-meter factory with more than 1,360 employees, while another lists 20 total employees; capacity cannot therefore be reliably quantified.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported in both the R&D and design-service information, indicating broad customization coverage.

Client casesThe supplier reports providing OEM services for known brands, which is evidence of at least one type of customer engagement. However, no brand names, project details, order examples, or independently verifiable customer case information is provided.
