PV Panel cleaning Brush WLS-2
With the explosive growth of photovoltaic (PV) installation scale, dust accumulation on modules has become a core bottleneck restricting power generation efficiency. Research shows that severe dust accumulation can reduce the power generation efficiency of PV panels by 15%-30%, and the annual power revenue loss of a 100MW-level power plant can reach millions of yuan. The WLS-2 Series Automatic PV Cleaning Machine, independently developed by WANLV SUNNY, is specially designed for large-scale ground-mounted PV power plants and rooftop distributed PV projects. It features “automated operation, efficient dust removal, and safety and reliability” as its core advantages, completely solving the pain points of traditional manual cleaning such as low efficiency, high cost, and high risk. It has become a key equipment for PV power plants to upgrade from “optional accessories” to “standard necessities.”
The series offers three flexible versions – Mains-Powered Version (WLS-2-1), Lithium Battery Version (WLS-2-2), and Dual-Use Version (WLS-2-3), which can adapt to the power supply conditions and cleaning scenarios of different power plants, fully meeting the diverse needs from remote Gobi power plants to urban rooftop PV systems.

Core Advantages: Redefining PV Cleaning Standards
1. Efficient Dust Removal, Immediate Improvement in Power Generation Efficiency
The WLS-2 Series adopts the collaborative operation of multiple sets of high-density rolling brushes, combined with an optimized bristle angle design. It has a cleaning width of 60cm and a cleaning speed of ≥6m/min, far exceeding the efficiency of manual cleaning. Its dust removal rate is as high as 92%, which can not only effectively remove floating dust and sand particles but also handle stubborn stains such as bird droppings and tree sap. After cleaning, the power generation efficiency of PV modules increases by an average of 15%-25%, and the investment payback period can be shortened to 3-5 years. It fully complies with the strict requirements for cleaning performance in GB/T 44264—2024 General Technical Conditions for PV Module Cleaning Robots.
It supports both dry and wet cleaning modes: dry wiping mode is selected in dry environments to avoid water waste; wet wiping mode is activated in scenarios with more oil stains, and combined with a low-pressure spray system, the cleaning effect is more thorough without damaging the PV panel coating.
2. Intelligent Automation, Freeing Up Labor Costs
Equipped with a high-precision infrared sensing and path planning system, it can automatically identify the edges of PV modules, obstacles, and string gaps, realizing “automatic cleaning upon startup” without the need for full-time manual monitoring. The mobile design supports flexible operation on PV arrays with an inclination angle of 5±2°, adapting to the installation scenarios of most ground-mounted power plants. A single device can cover a 10,000-square-meter PV area, significantly reducing labor input – especially in remote areas, it can reduce the proportion of labor costs in the cleaning link from more than 30% to less than 5%.
It is equipped with an intelligent control system that supports scheduled cleaning, remote start-stop and other functions. The cleaning cycle can be preset according to local wind and sand, rainfall patterns, ensuring that the modules are always in the best power generation state.
3. Upgraded Safety Protection, Adapting to Complex Environments
Strictly following the safety standards of GB/T 44264—2024, it builds a comprehensive protection system: the electric control box reaches IP55 protection level, which can resist sand and dust, rain and water erosion; it has built-in short-circuit protection, overload protection and anti-fall devices. When moving, it can automatically identify the edge of the array and stop urgently to avoid equipment damage caused by falling.
The structural parts adopt anti-corrosion treatment technology, and the anti-corrosion ability is not lower than the C2 environment requirements in GB/T 19292.1. It can operate stably in complex climates with a temperature range of -10℃ to 45℃ and a wind speed not exceeding 13.8m/s, adapting to various PV power plant scenarios such as deserts, Gobi, and plateaus. All exposed rotating parts are equipped with protective covers to further improve operational safety.
4. Multi-Version Power Supply, Adapting to Full-Scenario Needs
Targeting the power supply conditions of different power plants, it provides customized power solutions to completely break free from site restrictions:
- Mains-Powered Version (WLS-2-1): Powered by 220V mains, equipped with a 16m extended power cord, suitable for rooftop PV or centralized power plants with stable power supply nearby, enabling 24-hour continuous cleaning without frequent charging.
- Lithium Battery Version (WLS-2-2): Powered by a 24V/26Ah large-capacity lithium battery pack, supporting 4-6 hours of continuous operation, and only taking 5 hours to fully charge. Equipped with a portable battery backpack, it is suitable for remote Gobi and desert power plants without mains power, with flexible movement without being restricted by cables.
- Dual-Use Version (WLS-2-3): It has both mains and lithium battery dual power supply modes, which can be flexibly switched according to the on-site power supply situation. It is the best choice for mixed scenarios and emergency cleaning, ensuring uninterrupted cleaning work.
5. Durable Structural Design, Reducing Operation and Maintenance Costs
The telescopic rod is made of aluminum alloy with a wall thickness of 1.0mm (carbon fiber upgrade optional), with a maximum diameter of 40mm, combining light weight and high strength. The multi-length specifications of 3.5m-7.5m can adapt to the installation needs of modules at different heights. The rolling brush is made of new nylon wire material, which is soft and wear-resistant, avoiding scratches on the PV panel surface while resisting long-term friction and wear, and its service life is extended by 50% compared with ordinary bristles.
The equipment failure rate is extremely low. The failure rate is ≤0.3% during 1,000 round-trip operations in the same PV array, which is far better than the industry average, greatly reducing later operation and maintenance costs.
Applicable Scenarios: Cleaning Solutions for All Types of PV Power Plants
- Large-Scale Ground-Mounted PV Power Plants: Centralized power plants in deserts, Gobi, and plains, adapting to the cleaning needs of ultra-long strings. Automated operation reduces labor transportation and operation costs.
- Rooftop Distributed PV: Scenarios such as enterprise workshops, commercial buildings, and residential rooftops. The lightweight body combined with a flexible telescopic rod can easily cope with complex rooftop environments.
- Remote Power Plants Without Electricity: The lithium battery version does not require mains power and can achieve self-sufficiency when paired with solar charging panels, solving the power supply problem in remote areas.
- High-Dust Pollution Areas: PV projects around mining areas and industrial zones. High-frequency cleaning can effectively resist dust accumulation and maintain stable power generation efficiency.
After-Sales Support: Make Your Investment More Secure
