How to Choose the Right Solar Panel Cleaning Detergent?

Choose the appropriate cleaning agent based on the type of contaminant. A general-purpose neutral detergent is recommended.

What is the water consumption?

Water consumption is approximately 1 to 1.5 cubic meters per megawatt (MW) of solar panels cleaned, depending on conditions and cleaning mode. Water consumption is related to the flow rate of the high-pressure water pump used with the product.

Is the robot easy to operate? Does it have safety features?

The robot is remotely controlled, allowing flexible movement such as forward, backward, and turning in all directions. It also features an upgraded anti-fall sensor module, which helps prevent accidents such as falling from elevated surfaces, ensuring safe and stable operation.

Additionally, the product comes with a 1-year warranty for motor and battery, providing peace of mind for customers.

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:What is the daily cleaning capacity of the solar panel cleaning robot?

The robot can clean up to 1.2-1.8 megawatts (MW) of solar panels per day, significantly improving the efficiency of large-scale solar power plant maintenance.

Q:How is the robot powered and how long can it operate?

The robot is powered by 1 piece of 24V, 30Ah lithium batteries, offering strong endurance and high energy efficiency, suitable for extended operation. (Exact runtime may vary depending on the cleaning mode and terrain.) The working time is 4 hours for and 8 hours for 2 batteries.

Q:Can the robot only operate on flat surfaces? What is the maximum working incline?

Equipped with a crawler chassis, the robot can adapt to various terrains and operate on inclines of up to 15 degrees, making it suitable for most solar panel installations.

Q:How is water supplied during cleaning? Is a direct water source required?

The robot supports two water supply methods: (1). Direct connection to a faucet for continuous water supply through 0.5-5Mpa high pressure pump. (2). Use of an onboard water tank connected to an extended hose and high-pressure pump, ideal for remote areas without nearby water sources.

Q:Why I need a water filter?

This filtration solution enables customers to achieve: Safer solar module cleaning, More reliable system performance, Lower maintenance costs, Long-term energy yield protection.
