Photovoltaic Module Cleaning Robot

Ruitai's Photovoltaic Module Cleaning Robot adopts waterless dry-cleaning or low-water cleaning technology, making it environmentally friendly and well suited for water-scarce regions. It is equipped with an intelligent path-planning system, the robot can automatically detect module edges and obstacles to prevent collisions, while its lightweight design ensures safe operation without damaging the glass surface of photovoltaic modules.

Integrated with the TCU and SCADA platform, the cleaning robot can automatically start and stop based on dust accumulation levels or rainfall conditions, enabling truly unmanned operation and maintenance while significantly reducing manual cleaning costs and safety risks.

What Are the Functions of a Photovoltaic Module Cleaning Robot?

1. Automatic movement: The robot can move autonomously across the surface of photovoltaic modules or along rails, covering the entire cleaning area.

2. Automatic cleaning: The robot removes contaminants from the module surface using methods such as rotating brushes, roller brushes, or spraying.

3. Intelligent obstacle avoidance: It can detect and navigate around obstacles such as junction boxes, mounting brackets, and bolts.

4. Edge protection: Upon detecting the edge of a module, the device automatically stops or changes direction to prevent falling.

5. Remote monitoring: It supports remote status monitoring and task scheduling via an IoT platform.

FAQ

Q: What are the key advantages of this robot compared to traditional cleaning equipment?

A: Our Photovoltaic Module Cleaning Robot offers several key advantages, including lightweight design, smooth movement, no pressure on photovoltaic modules, low failure rates, and extremely low operation and maintenance costs.

It eliminates common challenges such as bulky designs, manual operation requirements, higher battery-related maintenance issues, and elevated operating costs, providing a more efficient and cost-effective cleaning solution for solar power plants.

Q: How much can a single cleaning improve solar panel performance?

A: Under normal operating conditions with typical dust accumulation, a single cleaning can increase power generation efficiency by 15%–30%. In environments with heavy dust, sand, airborne particles, or bird droppings, performance improvements can exceed 30%. The actual gain depends on the level of soiling and site conditions.

Q: Will the cleaning process damage or scratch the solar panels?

A: No. Our robot uses flexible, wear-resistant cleaning brushes specifically designed for photovoltaic applications. The brush material provides an optimal balance of softness and durability, ensuring that no hard metal components come into contact with the module surface.

The brush bristles have excellent elasticity and conform closely to the panel surface without causing hard friction. The system has undergone tens of thousands of factory tests and will not scratch tempered glass photovoltaic panels.

Q: What power source does the robot use? Does it draw power from the PV modules or the inverter?

A: The robot is designed to support both AC and DC power supplies, providing flexibility for different project requirements.

When operating on DC power, it is typically powered directly from the photovoltaic modules, offering a simple, efficient, and safe power supply solution.

Q: Can the robot operate in rainy or windy conditions?

A: Our robot is installed close to the photovoltaic modules, with a clearance of only 10 cm from the module surface.

Therefore, regardless of wind or rain, as long as the modules are able to generate power normally, the robot can continue to operate normally.
