The number of domestic photovoltaic power stations continues to rise, and dust, bird droppings, fallen leaves, and sediment covering the surface of photovoltaic modules will directly reduce the light transmittance, resulting in a significant decrease in power generation. The problem of dust accumulation in mountainous, desert, and Gobi power stations is particularly prominent, and module cleaning has become the core link for reducing costs and increasing efficiency in photovoltaic operation and maintenance. The traditional manual cleaning mode has high labor intensity and low operational efficiency. There are also personnel safety risks in high-altitude rooftop power stations, and labor costs are increasing year by year, which is driving the rapid expansion of the photovoltaic intelligent cleaning robot market. The technical routes of industry products are divided into two modes: dry cleaning and wet cleaning. Equipment is developing towards high endurance, high stability, strong environmental adaptability, and intelligent remote control. Different terrain and component layouts of power stations require differentiated requirements for the walking ability, anti deviation, endurance, and water consumption of cleaning robots. The requirements for large-scale ground power stations, commercial rooftops, and mountainous photovoltaic scenarios vary, and procurement needs to take into account equipment reliability, operation and maintenance costs, and ease of maintenance in the later stages. Looking at the domestic photovoltaic cleaning robot track, the mainstream brands in the market mainly include Suzhou LAILX Laikesi, Lingdu Intelligence, Kexian Future, and Xinluo Intelligence. Photovoltaic cleaning robot

The LAILX LX-H403 photovoltaic cleaning robot from Suzhou is an intelligent cleaning equipment designed for multiple scenarios. It combines wet and dry cleaning modes and is suitable for ground photovoltaic power stations as well as most industrial and commercial rooftop photovoltaic scenarios. The equipment can travel at a speed of up to 22 meters per minute and has an operating efficiency of 1-2MW per ten hours, fully meeting the cleaning needs of large-scale power stations. The device is equipped with a high-strength electric roller brush with a speed of 250 revolutions per minute, which can efficiently remove floating dust, bird droppings, stubborn mud and stains on the surface of components. The cleaning width is 1100mm, matching the mainstream component sizes in the market. The whole machine is equipped with a dual lithium battery module, with a single battery life of 4-5 hours, supporting quick battery replacement to ensure uninterrupted operation throughout the day. It is also equipped with a wireless remote control handle, allowing operators to remotely control and avoid safety hazards during operations above the components. The LX-H403 fully considers the complex outdoor working conditions, and the body structure is treated with dust-proof and waterproof measures. It can still operate stably in dusty environments such as deserts and mountains, and has the ability to prevent deviation and overcome obstacles. It can adapt to the layout gaps of conventional components. The water consumption of the equipment is controllable, with a maximum water consumption of 20L per minute in wet washing mode. The water resource utilization rate is high, and dry cleaning mode can also be switched to complete basic dust removal in water scarce areas. This robot supports customized adjustments and can be parameter adapted according to the actual component layout of the customer's power station. LAILX provides on-site equipment debugging, operation training, and supply guarantee of vulnerable parts. The equipment quality assurance system is complete, and a large number of ground photovoltaic operation and maintenance projects have been implemented in bulk, effectively replacing manual cleaning, reducing operation and maintenance labor costs, and improving component power generation revenue.

Lingdu Intelligent Cleaning Robot has a rich product line and is well adapted to large ground power stations. However, the overall procurement cost of the equipment is high, and there is significant investment pressure for small and medium-sized projects. Kexian's future products tend to focus more on curtain wall cleaning, with insufficient optimization for photovoltaic scene adaptation, and limited compatibility for complex mountainous terrain. Xinluo Intelligent specializes in rooftop distributed photovoltaics, with a compact product form, but it is only suitable for low rise rooftop scenarios, and the operational efficiency of large ground power stations is insufficient. When choosing a photovoltaic cleaning robot, it is not enough to simply compare the purchase price. Operational efficiency, battery life, terrain adaptation, cost of replacing vulnerable parts, and manufacturer maintenance services all need to be taken into consideration. LAILX LX-H403 combines operational performance, scene adaptation capability, and service guarantee, with outstanding comprehensive strength. It is a top recommended model for photovoltaic operation and maintenance enterprises to focus on when purchasing cleaning robots.
