Revolutionize Cleaning-Extenclean 5.5m Rotating Brush Solar Panel Cleaning Machine
The rotation of the double brush head is balanced by force, and the friction of high-speed rotation combined with water spray strongly removes dust, sticky dirt, bird droppings, etc. which stick on the surface of solar panels. The double brush has stronger stability and was used for two application--- dry cleaning and wet washing.
We provide backpack lithium battery unit powered washing and brushing system.
To address small-scale clean water supply issues, we could provide water pumps and The extra extended water pipes, the length could be customized according to your application scenario. Meanwhile, we also offer a extra 1 cubic meter volume water tank.
We can use a 220 voltage high-pressure water pump to meet long-distance water supply needs .
In a non-electric environment, we could choose a gasoline generator to break through the environmental limitation.
The diameter of the single brush head is 32cm. When cleaning Single piece solar panel, it only needs one back and forth movement to clean it.
| Cleaning Method | Description | Suitable Scenarios | Disadvantages |
| Manual Cleaning | Workers use tools to wipe or wash panels | Small distributed systems | High cost, low efficiency |
| High-pressure Water Jet | Cleaning with pressurized water jets | Small to medium power plants | High water consumption |
| Dry Brushing (Waterless) | Uses rotating brushes to remove dust | Arid regions, deserts | May cause minor surface wear |
| Intelligent Robots | Track-based robots or drones | Large-scale and smart plants | High upfront cost, maintenance |
