WLS-7-LM Intelligent Solar Panel Cleaning and Inspection Robot for PV Farms

Product Overview

The WLS-7-LM Intelligent Solar Panel Cleaning and Inspection Robot is a next-generation solution designed for centralized photovoltaic power stations. Engineered for large-scale solar farms, this system integrates autonomous cleaning and real-time inspection capabilities to enhance energy efficiency, reduce operational costs, and support long-term system stability.

Built for demanding environments such as deserts and high-dust regions, the robot combines intelligent automation with robust mechanical performance, making it a reliable choice for utility-scale solar maintenance.

Intelligent Dual Function System

The WLS-7-LM is not only a cleaning device but also a smart inspection platform. It performs two essential tasks in a single operation cycle:

• Automated photovoltaic panel cleaning

• Real-time system condition monitoring and inspection

This dual-function design helps solar farm operators streamline maintenance workflows while improving overall system visibility and performance management.

Autonomous and Remote Operation Modes

The system supports both manual remote control and fully autonomous driverless operation. Operators can switch between modes depending on site conditions and operational requirements.

Operational flexibility includes:

• Fully autonomous route execution for large solar fields

• Remote-controlled precision cleaning for targeted maintenance

• Adaptive navigation across complex PV layouts

This flexibility ensures efficient deployment across different types of solar installations.

Adaptive Cleaning for Complex Solar Environments

The robot is engineered to operate across varied photovoltaic panel structures, including different tilt angles and installation heights. Its self-adjusting cleaning posture allows stable operation even on uneven terrain.

Key adaptability features:

• Automatic adjustment to panel slope and height

• Stable movement across large PV arrays

• Reliable performance in uneven or challenging ground conditions

This ensures consistent cleaning quality across the entire solar farm.

Intelligent Sensing and Inspection System

Equipped with advanced sensors, the WLS-7-LM continuously monitors operational conditions during cleaning.

Real-time monitoring includes:

• Cleaning pressure control

• Tilt and alignment detection

• Surface condition evaluation

• Abnormal panel identification

The system automatically generates inspection reports, helping maintenance teams quickly identify issues and plan corrective actions.

Dual Roller Brush Cleaning Technology

At the core of the system is a dual-row roller brush mechanism designed for high-efficiency dust removal.

Cleaning advantages:

• Opposite-direction brush rotation for enhanced friction

• Deep cleaning of tight panel gaps

• One-pass cleaning efficiency

• Reduced water and energy consumption

This structure ensures thorough cleaning while maintaining low operational resource usage.

Centralized Control and Data Visualization

All operational data from the robot is transmitted to a centralized control interface. This allows supervisors to monitor cleaning performance and system status in real time.

Control system capabilities:

• Visualized cleaning routes and job paths

• Real-time performance tracking

• Remote system supervision

• Data-driven maintenance planning

This improves decision-making efficiency and operational transparency across solar farms.

Power System and Endurance Performance

The WLS-7-LM is equipped with a hybrid power system combining a generator and battery pack, ensuring stable long-duration operation.

Power system benefits:

• Continuous operation for extended cleaning cycles

• Reduced downtime in large solar farms

• Stable energy supply in remote environments

Its endurance capability supports full-day cleaning operations without interruption.

Strong Terrain and Environmental Adaptability

Designed for challenging conditions, the robot performs reliably in harsh environments such as deserts and high-temperature regions.

Environmental capabilities:

• High dust and sand resistance

• Strong slope-climbing ability

• Obstacle-crossing performance

• Stable operation in extreme climates

These features make it suitable for utility-scale photovoltaic projects worldwide.
