AI-Powered supplier vetting

SummarySUNROVER POWER CO., LTD. is identified as a Hefei-based trading company associated with the power, heat, gas, and water supply industry. It offers solar panels, batteries, inverters, and solar systems, including a stated 625W N-type monocrystalline bifacial panel. The company reports establishment in 2014, more than seven years of industry experience, state-level high-tech enterprise status, over 30 solar-related patents, and ISO9001, ISO14001, and ISO45001 certifications for solar panel products. It also describes a 50,000-square-meter production workshop and annual solar-panel capacity of 1 GW planned for 2021. An SGS audit record exists, but the audit result is recorded as “0” without an interpretable explanation, and its validity period ended in 2025. Overseas services, detailed quality systems, R&D services, customization, after-sales capabilities, and sustainability systems are largely marked unknown. One recorded trade transaction and one associated buyer provide limited customer evidence.

Supplier typeThe supplier is explicitly classified as a trading company located in Hefei, with associated companies in the power, heat, gas, and water supply industry. Its listed products cover solar panels, batteries, inverters, and solar systems, and a specific solar-panel product is recorded.

CertificationsThe company states that its solar-panel products hold ISO9001, ISO14001, and ISO45001 certifications, and an SGS audit record is listed. However, the SGS report expired on 2025-05-27 and its evaluation result “0” is not explained, so the current audit standing is not established.

R&D capabilityThe company describes itself as a state-level high-tech enterprise with more than 30 solar-related patent certificates and reports planned solar-panel production expansion. Specific evidence for current R&D documentation, SDK development, private-mold design, 3D design, or ODM services is marked unknown.

Production capacityThe company reports more than seven years of production and manufacturing experience and states that a 50,000-square-meter solar-panel workshop would support annual capacity of 1 GW from 2021. Its product listing includes a 625W bifacial solar panel, but the provided records do not independently confirm current capacity utilization or manufacturing ownership.

Client casesThe trade record shows one transaction, one associated buyer, and Ghana listed among imported-goods countries. This is direct evidence of at least one recorded customer transaction, but the limited volume and absence of project details do not demonstrate broad customer coverage or substantial case experience.
