Maximizing Solar Yield through Professional Soiling Removal
The WLS-5 Series is a high-performance, rolling brush solar cleaning system designed to combat energy loss caused by dust, bird droppings, and industrial pollutants. Featuring a unique ergonomic gooseneck design and triple-power mode flexibility, the WLS-5 is the industry standard for commercial rooftops and utility-scale solar farms.
Key Features & Advantages
1. Ergonomic Gooseneck Design (Effortless Operation)
Unlike traditional straight poles, our patented gooseneck curve allows operators to apply downward pressure more naturally. This “human-mechanics” design reduces physical fatigue and ensures the brush head maintains 100% contact with the panel surface for a streak-free finish.
2. Triple Power Versatility (Plug-in / Lithium / Dual)
To adapt to various O&M (Operation and Maintenance) environments, the WLS-5 is available in three versions:
Mains Version (WLS-5-1): Unlimited runtime with a 220V to 24V power converter. Ideal for accessible rooftops.
Lithium Battery Version (WLS-5-2): Features a high-capacity 24V 26Ah battery backpack. Perfect for remote solar plants without on-site power.
Dual-Use Version (WLS-5-3): The ultimate hybrid solution, allowing you to switch between battery and mains power as needed.
3. All-Weather Dry & Wet Cleaning
Equipped with a 60cm wide specialized nylon brush, the WLS-5 supports:
Water-Fed Cleaning: Integrated water jets for removing stubborn grime.
Dry Sweep Mode: High-speed rotation (700 r/min) to clear sand and dust in arid regions without wasting water.

Frequently Asked Questions (FAQ) – WLS-5 Solar Cleaning System
Q1: Why is the WLS-5 rolling brush more efficient than traditional solar mops?
A: The WLS-5 features a high-torque 150W DC motor with a rotation speed of 680-700 r/min. Combined with a 60cm ultra-wide brush head, it cleans up to 10 times faster than manual tools. It effectively removes stubborn bird droppings, heavy dust, and industrial pollutants, helping to restore solar energy output by 15% to 30%.
Q2: Does the WLS-5 support dry cleaning in desert or water-scarce areas?
A: Yes. The WLS-5 is a versatile wet and dry dual-use machine. In arid regions, its high-density, anti-scratch nylon bristles can sweep away sand and dust without using water. For deep cleaning, it can be connected to a water source to provide a pressurized wash that rinses away sticky grime.
Q3: What is the battery life of the WLS-5-2 Lithium Battery Version?
A: The Lithium Battery Version is equipped with a high-capacity 24V 26Ah battery backpack. It provides a continuous runtime of 3.5 to 4.5 hours on a single charge. Recharging takes approximately 6-7 hours. This cordless design is ideal for large-scale ground-mounted solar farms or rooftops where power access is limited.
Q4: How does the “Gooseneck Design” improve cleaning performance?
A: Our unique Gooseneck curve is an ergonomic breakthrough in solar maintenance. Unlike straight poles that require manual lifting, the curved design allows operators to apply downward pressure more naturally. This ensures the brush head maintains consistent contact with the panels, even at a 7.5-meter distance, reducing physical strain and ensuring no spots are missed.
Q5: Is the brush material safe for anti-reflective (AR) coated solar glass?
A: Absolutely. The WLS-5 uses specialized soft-filament nylon brushes. The bristle stiffness is precisely calibrated to be tough on dirt but gentle on glass. It will not scratch the tempered glass or damage sensitive anti-reflective (AR) or hydrophilic coatings on modern photovoltaic modules.
Q6: How is the product packaged for international shipping?
A: We use reinforced industrial-grade packaging to ensure zero-damage delivery.
The Brush Module is housed in a shock-proof carton (75×47×22cm).
The Telescopic Pole is shipped in a separate, rigid, high-impact cylindrical tube (160-203cm) to prevent bending during sea or air freight.
Q7: Can I customize the pole length or order under my own brand?
A: Yes, Wuxi Wanlv Intelligent Technology Co., LTD. is a professional OEM/ODM manufacturer. We offer customization for pole lengths (up to 7.5m+), material upgrades (carbon fiber poles), and private labeling (Logo branding) for professional solar O&M service providers.
