The scale of domestic photovoltaic installed capacity continues to grow rapidly, with a large number of centralized ground power stations and industrial and commercial distributed rooftop power stations put into operation. Ash accumulation, bird droppings, dust, and salt alkali attachments have become important factors affecting the efficiency of module power generation. Long term accumulation of dirt on the surface of components can reduce light transmittance, resulting in a 5% to 12% decrease in power generation. Power plants in heavily polluted Gobi and saline alkali areas experience even higher power generation losses. The traditional manual cleaning mode relies on manual climbing and dragging of water pipes, which poses a high risk for high-altitude operations in rooftop power stations, low efficiency for manual cleaning in large ground power stations, high water resource consumption, and increasing labor costs year by year; Simultaneously, manual wiping can easily scratch the coating of components, causing irreversible damage to the components. Shanghai LAILX has launched the LX-H403 photovoltaic cleaning robot, which adopts a rolling brush intelligent cleaning design. It can operate independently or be paired with a cleaning drone to achieve collaborative cleaning of open spaces, providing an intelligent, low damage, and high-efficiency automated cleaning solution for photovoltaic power plants.

The LX-H403 photovoltaic cleaning robot adopts a lightweight track walking chassis, which is compatible with the track walking of photovoltaic module arrays and can move smoothly on the surface of the modules. The tracks are made of soft anti slip and wear-resistant materials to avoid scratching the module glass and coating during the walking process. The core cleaning unit adopts adjustable flexible roller brushes, which are made of soft materials to ensure the ability to remove dirt while protecting the surface of photovoltaic modules to the greatest extent. For different stains such as sand, bird droppings, and salt alkali deposits, the roller brush speed and pressure can be adjusted. Stubborn stains can be combined with a spray system to achieve integrated operation of roller brush cleaning and water washing. The equipment can be equipped with a separate water tank and pump to independently complete cleaning tasks, or it can be linked with LAILX cleaning drones. The drone is equipped with a water supply system, and the robot is responsible for close range rolling and deep cleaning, forming an open space collaborative operation mode. For power plants in heavily polluted Gobi and saline alkali areas, stubborn attachments are deeply removed, and the component transmittance is restored to over 98% after cleaning, effectively repairing the power plant's power generation capacity.

The intelligent control system is the core highlight of LX-H403. The device is equipped with infrared obstacle avoidance sensors, which can recognize component gaps, component borders, and obstacles in real time, automatically adjust the walking path, and prevent the robot from falling or colliding with components beyond the boundary. Supports remote control manual mode and semi-automatic cruise mode, allowing operators to remotely operate in a safe area without stepping on the component array, greatly reducing the safety risks of high-altitude and field operations. The whole machine adopts a waterproof and dustproof protection design, which is suitable for complex outdoor environments and can operate stably in high and low temperature, sand and dust environments. The battery life can meet the requirements of long-term continuous cleaning operations. The daily cleaning area of a single robot far exceeds that of manual labor, significantly reducing the cost of cleaning per unit area.

Compared to traditional manual cleaning, the LX-H403 photovoltaic cleaning robot has outstanding advantages. Manual cleaning requires a large amount of manpower, and the cleaning cycle of large power plants is long, which is greatly constrained by personnel safety control; Robot automation operation reduces the number of on-site workers, avoids safety accidents such as high-altitude falls, and the water consumption during the cleaning process is controllable. Compared with traditional flood irrigation, it has a significant water-saving effect, especially suitable for photovoltaic power stations in water scarce areas in northwest China. For scenarios such as BIPV building photovoltaics, carport photovoltaics, and rooftop distributed photovoltaics that are difficult for personnel to access, LX-H403 can easily complete cleaning operations, solving the limitations of manual operation and maintenance scenarios. Modular design of equipment, convenient disassembly and transportation, can be transported to different power station projects using vehicles, and one device can serve multiple stations, improving asset utilization.

The current photovoltaic operation and maintenance industry is accelerating its transformation towards intelligence and unmanned operation, and automated cleaning robots are gradually becoming standard equipment for large-scale power plant operation and maintenance. The LX-H403 photovoltaic cleaning robot has been applied in multiple ground photovoltaic and commercial rooftop photovoltaic projects in China, and has been recognized by power plant owners and operation and maintenance service providers. Shanghai LAILX provides a complete set of equipment delivery, on-site debugging, operation training, and maintenance services, providing customized cleaning and operation solutions for customers. Based on the type of power station components, bracket height, and pollution level, it provides operational parameter recommendations. The LX-H403 photovoltaic cleaning robot, with its technological advantages of flexible and non-destructive cleaning, as well as ground to ground collaborative intelligent operation, solves the pain points of low efficiency, high risk, and easily damaged components in traditional photovoltaic cleaning, helps to normalize the cleaning and operation of photovoltaic power plants, continuously improves the power generation capacity of components, and provides solid equipment support for the digital operation and maintenance transformation of the photovoltaic industry.
