AI-Powered supplier vetting

SummaryWuxi Wanlv Intelligent Technology Co., Ltd is identified as a China-based manufacturer/factory in Jiangsu, although another record describes the company nature as a trading company, creating an entity-classification inconsistency. The supplier offers solar panel cleaning brushes and robots, reports three production lines, 30,000 pieces of annual solar-panel-cleaning-machine productivity, 11–20 years of R&D engineer experience, and 6–10 quality-control staff. Its stated management certifications are OHSAS/OHSMS 18001 and ISO 9001. The company describes 24-hour after-sales assistance and flexible cleaning solutions. Evidence is insufficient to confirm financial credibility, customization or broader innovation services, and customer cases are not documented. Several operational, sustainability, OEM/ODM, overseas-service, and traceability attributes remain unknown.

CertificationsThe supplier reports OHSAS/OHSMS 18001 and ISO 9001 certification of its management systems. The provided slice does not include certificate scope, validity, or issuing details, but it explicitly records the certifications.

After-Sales capabilityThe company states that it provides an after-sales protection system and 24-hour after-sales assistance, intended to address customer concerns. This is explicit evidence of an after-sales service offering, although no service-level metrics or geographic coverage are provided.

R&D capabilityThe company states that it continuously optimizes its solar-module cleaning robot system and cleaning technology, and its R&D engineers have 11–20 years of total experience. ODM, SDK, private-mold, 3D-design, new-product, and last-year product-launch information is marked unknown, so broader innovation capability cannot be fully established.

Production capacityThe supplier reports three production lines, 6–10 quality-control staff, and annual productivity of 30,000 solar-panel-cleaning machines; export sales are reported at 51%–70%. These figures provide explicit evidence of production capacity, while order-fulfillment status is recorded only as “6” without a defined scale.

Product Q&A

Q:Can this drone be used at night or in low-light conditions?

Yes. Equipped with FPV HD cameras and landing lights, it ensures safe operation during nighttime or low-visibility conditions.

Q:Is the drone suitable for cleaning rooftop solar panels?

Certainly. The WLS-9YQ-LD1 drone excels in cleaning rooftop PV systems without scaffolding or manual climbing.

Q:How does the drone avoid damaging the solar panels during cleaning?

It uses a non-contact, high-pressure spray to clean without physical contact, preventing scratches and micro-cracks from brushes or manual methods.

Q:What kind of cleaning liquid can be used with this drone?

It supports most solar panel cleaning solutions or deionized water. Ensure to use eco-friendly, non-abrasive liquids to maintain panel longevity.

Q:How is the drone different from a solar cleaning robot?

Unlike solar cleaning robots, this drone requires no rails and adapts to uneven terrains such as roofs, hills, and deserts, offering superior flexibility with no installation cost.
