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.
7.Is there a warranty?
Additionally, the product comes with a 1-year warranty for motor and battery,providing peace of mind for customers.
