PV Cleaning Robot

Ruitai offers a high-efficiency PV cleaning robot that combines a lightweight structure with high strength and durability. Its tracked drive system increases contact with the solar panels, reducing pressure on the panel surface while improving its ability to cross gaps between panels for smoother, more stable operation.

Its push-sweeping dry-cleaning technology is designed for loose surface dust. It removes dust from solar panels quickly without using water, helping prevent secondary contamination.

Product Key Features

Full Product Range for Different Solar Applications

The equipment range of Ruitai includes handheld cleaning brushes, tracked and suspended cleaning robots, and water-cleaning equipment.

Our PV Cleaning Robot is suitable for solar power plants of different sizes and terrains, from large ground-mounted plants to distributed commercial and industrial rooftop projects, providing efficient and complete cleaning coverage.

Intelligent Cleaning for Reliable Performance

The robots use high-precision radar and camera sensors to support autonomous navigation and intelligent obstacle avoidance. Combined with roller brushes, vacuum systems, and water-spray systems, they can efficiently remove dust, sand, snow, bird droppings, and other stubborn contaminants, improve light transmission and help maintain solar power generation efficiency.

Standardized Maintenance for Longer Equipment Life

The equipment comes with a structured maintenance system based on daily, weekly, monthly, quarterly, and annual schedules.

Clear maintenance guidance helps extend equipment life and ensures that every cleaning operation remains safe and efficient.

Full Lifecycle Maintenance Guidelines

1. Daily Maintenance (Before and After Operation)

● Before operation

- Check screws and fasteners, tracks, and rollers.

- Confirm battery level, emergency stop button, and communication signal.

- Remove loose dust and debris from sensors and roller brushes.

- For water-cleaning models, check the pipes for leaks and drain any remaining water.

- Finally, carry out a no-load test run.

● After operation

- Turn off the power and remove mud and sand from the machine body and cooling vents.

- Rinse and dry the roller brushes.

- Fully drain the water system to prevent freezing and cracking in winter.

- Wipe the sensors with a soft, dry cloth.

- Charge the battery promptly and store it at 50%–80% capacity.

2. Weekly Maintenance (Every 7 Days)

- Remove tangled debris from the roller brushes and stones from the tracks, then adjust track tension.

- Apply lithium-based grease to transmission parts such as bearings and gears.

- Check the waterproof sealing strips and electrical compartment.

- Test safety functions, including obstacle avoidance and fall prevention.

- Clean the water inlet filter and spray nozzles.

3. Monthly Maintenance (Every 30 Days)

- Perform a deep battery charge and discharge cycle to maintain battery activity.

- Fully tighten the screws on the chassis and travel mechanism.

- Check roller brush wear and adjust the cleaning pressure.

- Replace aged sealing rings and remove scale from the water pipes.

- Clean dust inside the electrical compartment and inspect the wiring for potential issues.

4. Quarterly and Annual Deep Maintenance

● Quarterly Maintenance (Every 3 Months)

- Replace heavily worn roller brushes and nylon bristles.

- Inspect and replace aged or worn parts.

- Calibrate the sensors and navigation system, update the control software

- Apply anti-corrosion and rust-prevention treatment.

● Annual Maintenance (Every 1 Year)

- Professional personnel should carry out a full inspection after disassembling the equipment.

- Check the condition of the motor, water pump, and battery.

- Replace aged sealing and transmission parts, perform complete rust removal and anti-corrosion treatment.

- Fully upgrade the software system, and maintain a record of wear parts.

Customized Maintenance for Special Environments

When using the PV Cleaning Robot, maintenance schedules should be adjusted for extreme and special environments.

Saline-Alkali and Coastal Solar Power Plants

Increase maintenance frequency to 1.5 times the standard schedule.

Remove salt deposits from equipment surfaces weekly and focus on rust prevention each month.

Mountainous and Windy-Sandy Areas

Strengthen daily dust removal and lubricate transmission parts every two weeks to prevent sand and dust from entering the equipment.

Low-Temperature Winter Environments

Fully drain the water system after each operation and add antifreeze.

Do not leave any water inside the equipment, as freezing may cause damage.

FAQ

Q: Can this PV cleaning robot handle PV arrays with varying tilt angles?

A: Yes. The unit features excellent climbing and obstacle-traversal capabilities, allowing it to operate stably on PV arrays with tilt angles of up to 35 degrees.

Its drive system and chassis structure are optimized to provide sufficient traction even on steep slopes, preventing slippage or falls.

Q: How does the robot detect and avoid obstacles within the array?

A: The unit is equipped with multiple high-precision sensors that detect obstacles along its path in real-time.

Upon detecting an obstacle, it immediately executes a preset avoidance routine—such as lifting the cleaning module or adjusting its movement posture—to smoothly clear the obstacle before resuming cleaning operations, all without requiring manual intervention.

Q: Which communication protocols does the communication module support?

A: Ruitai’s cleaning robots connect to the power plant network via a Smart Communication Unit (NCU), supporting various communication methods such as 4G/5G and fiber optics.

Regarding protocols, the system supports industry-standard industrial communication protocols like Modbus TCP/RTU, enabling seamless data integration and command exchange with SCADA systems from major brands and third-party O&M platforms.
