The Ultimate Solution for Utility-Scale Efficiency and ROI Optimization
Why Manual Cleaning is Costing You Money
In modern PV power plants, traditional cleaning methods are no longer viable. Manual pole cleaning is slow, hazardous for workers, and often leads to uneven cleaning that causes “Hot Spot” effects. The WLS-7PRO is engineered to bridge this gap, offering a smart, remote-controlled alternative that delivers consistent results across the most challenging terrains.
Key Performance Pillars
1. Intelligent “Zigzag” Navigation
- Total Coverage: Our proprietary path-planning algorithm ensures >99% surface coverage, eliminating the “blind spots” common with manual labor.
- Cruise Control:Set your parameters and let the robot work. A single unit can maintain a cleaning capacity of up to 12,000 $m^2$ per day.
- Self-Correcting Steering:If the robot encounters an unexpected skid or offset due to wet surfaces or external force, the system corrects the vehicle body within seconds to stay on path.
2. Adaptive Speed & Power
- Precision Cleaning:Features a maximum marching speed of 40 m/min.
- Dynamic Adjustment: Switch between 20 m/min, 30 m/min, or 40 m/min depending on the environment. Use lower speeds for deep-cleaning bird droppings and higher speeds for light daily dust maintenance.
- Long Endurance:Equipped with an internal lithium battery providing 4-5 hours of continuous operation (with an optional 8-10 hour long-life version available).
3. Safety-First Engineering
- Anti-Drop Protection: Built-in ultrasonic sensors detect the edge of the photovoltaic panels. The robot will automatically trigger a stop-and-return command if no panel is detected beneath it.
- Fail-Safe Braking:In the event of power loss, travel motors lock within 0.5 seconds to prevent the machine from rolling or falling.
- Steep Slope Stability: The anti-slip caterpillar tracks are designed for high-grip performance, supporting working angles up to 20°.

Frequently Asked Questions (FAQ)
Q: Can it be used for dry cleaning?
A: Yes. The combination of the electric rolling brush and high-torque motors allows for efficient dry cleaning in arid regions where water is scarce.
Q: Is it safe for the panels?
A: Absolutely. The robot is designed with lightweight materials (51kg) and distributed weight through its tracked chassis to ensure no micro-cracks are formed on the PV glass.
Q: What is the warranty coverage?
A: We provide a 12-month warranty for the drive motors, lithium battery, and charger, and a 6-month warranty for electronic components.
