With a remarkable remote control range of up to 150 meters, our cleaning robot provides unrivaled convenience and flexibility. Enhance the efficiency of your solar panel cleaning operations. The maximum working inclination angle of the robot is 15 degrees. It can clean up to 1.2MW of solar panels in a single day.
The crawler chassis of our remote control solar panel cleaning robot is for all terrain operations.
We used two pieces of lithium battery as the power supply for our cleaning robot, the working time is about 4-5 hours. The nominal voltage of the battery is 24 voltage and the capacity of the battery is 26 Ampere-hour.
Our robot has two water supply methods. The first is to directly connect the faucet to provide water, and the other is to install a water tank and connect an extended water pipe and pressurized water supply through a high-pressure water pump to break through the limitation of water sources.
Featuring a robust track chassis, our Remote-controlled Solar Panel Cleaning Robot can effortlessly navigate through any terrain, ensuring comprehensive cleaning coverage. Equipped with electric brush cleaning technology, this versatile machine allows for both dry and wet cleaning methods, guaranteeing optimal cleanliness for your solar power installations. Recently, our cleaning robot has also upgraded its sensor module and added an anti-fall function.
By using the remote control, the robot can move forward, backward, turn left and right, etc., so that it can walk in any direction on the photovoltaic panels and perform all-round cleaning operations without blind spots.
The front end of the robot is equipped with a rotating cleaning roller brush, and the upper end of the roller brush is equipped with a water spray nozzle. The combination of the two achieves efficient cleaning of solar panels.

Meanwhile, we offer consumers a great after-sales protection system, and positive reaction after-sales assistance available 24 hours a day, to solve all the worries.The photovoltaic cleaning brush plays a crucial role in the maintenance of photovoltaic power stations. Here are some key advantages of photovoltaic cleaning brushes:
Equipped with a high-efficiency motor and scientifically designed bristles, the brush can quickly clean large areas of photovoltaic panels, significantly reducing manual labor time.
Some products support automated or semi-automated operation, further enhancing efficiency.
The brush bristles are soft yet durable, effectively removing dust, sand, bird droppings, and other debris without scratching the glass surface of the panels.
Anti-static design reduces dust re-adhesion, extending the duration of the cleaning effect.
Utilizes micro-water or waterless cleaning technology, reducing water consumption - particularly suitable for arid and water-scarce regions.
Some models are equipped with water recycling systems for further water conservation.
Designed to be lightweight, making it easy to operate in challenging terrains such as mountains or deserts.
Certain models feature dustproof and waterproof designs, ensuring reliable performance in outdoor conditions.
Equipped with remote control, scheduled operation, and path-planning functions, enhancing convenience.
Sensors can monitor the cleanliness of photovoltaic panels and automatically determine when cleaning is needed.
Regular cleaning effectively reduces dust blockage, improving light absorption and significantly boosting photovoltaic panel power output.
With efficient cleaning capabilities and minimal labor requirements, operational and maintenance costs are significantly lowered, improving overall economic benefits.

1. What is the daily cleaning capacity of the solar panel cleaning robot?
The robot can clean up to 1-1.2 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 two pieces of 24V, 26Ah 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 4-5 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.
4. 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.
(2). Use of an onboard water tank connected to an extended hose and high-pressure pump, ideal for remote areas without nearby water sources.
5.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.
6. 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.
