Professional Solar Cleaning Robot for Efficient PV Panel Maintenance
Keeping photovoltaic panels clean is essential for maintaining high power output and extending the service life of solar power stations. The WLS-7 solar cleaning robot is a professional solar panel cleaning machine designed specifically for large-scale PV plants and hard-to-reach installation environments where manual cleaning or telescopic tools are ineffective.
As an advanced piece of solar panel cleaning equipment, the WLS-7 Pro provides a safe, efficient, and cost-effective solution for daily and periodic solar panel maintenance.
The WLS-7 is more than a single device-it functions as a complete solar panel cleaning system.
Equipped with a high-efficiency solar panel cleaning brush and integrated water spray nozzles, the robot removes dust, sand, bird droppings, and other contaminants without damaging the panel surface.
Unlike traditional manual tools or simple cleaning brushes, this solar panel cleaning robot can move freely in all directions across photovoltaic panels, ensuring full coverage with no blind spots.
Compared with solar panel cleaning equipment, the WLS-7 Pro offers several practical advantages for solar power plant operators:
No flight time limitations or aviation restrictions
Stable and continuous cleaning performance
Lower maintenance and operation costs
Suitable for daily, large-area cleaning tasks
With a cleaning capacity of up to 1.2MW per day, the WLS-7 Pro solar cleaning robot significantly improves operational efficiency while reducing labor dependency.
The WLS-7 Pro solar cleaning robot adopts wireless remote control technology with a control distance of up to 150 meters, allowing operators to clean panels remotely and safely.
Its robust drive motor, lithium battery system, and durable roller brush make it suitable for various PV tilt angles and complex installation environments.
This solar panel cleaning machine is especially ideal for:
Ground-mounted solar power stations
Large commercial and industrial PV systems
Areas where workers cannot safely stand or access panels
Manufactured by Wuxi Wanlv Intelligent Technology Co., Ltd. (WANLV SUNNY), the WLS-7 Pro reflects years of experience in developing professional solar panel cleaning equipment for the global market.
As a trusted supplier from China, WANLV SUNNY provides:
Stable product quality
Customized solutions for different PV projects
Long-term technical support and spare parts supply
If you are looking for a durable and efficient solar panel cleaning robot to improve energy output and reduce maintenance costs, the WLS-7 is a proven solution trusted by PV operators worldwide.
1. 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.
2. 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.
3. 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.
7.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.
8. 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.
9.Is there a warranty?
Additionally, the product comes with a 1-year warranty for motor and battery,providing peace of mind for customers.
