Industry data shows that dust, bird droppings, sand and other pollutants on PV panel surfaces can cause power generation losses of 5%-10%, and may even create hot spots that damage modules. Traditional manual cleaning methods are not only inefficient but also pose safety risks for high-altitude work. According to the China Photovoltaic Industry Association, China’s smart PV cleaning robot market reached 6.45 billion yuan in 2026, representing a year-on-year growth of 32.6%, with the domestic cleaning and weed control market expected to exceed 25 billion yuan by 2030. Robot cleaning penetration is projected to rise from the current 15% to 42%.

Intelligent Cleaning Technology
The company’s core product, the MR-G series intelligent solar panel cleaning robot, is specifically designed for PV power plants. It moves left and right along the PV array and utilizes a rotating brush mechanism to provide efficient, non-abrasive dry or wet cleaning for solar panels. The product series is suitable for various applications including:
- ✓ Large-scale ground-mounted PV plants
- ✓ Centralized PV plants
- ✓ Fishery-PV complementary systems
- ✓ Distributed & Industrial rooftop PV
The newly launched third-generation MR-G3 cleaning robot offers even greater advantages in performance, product design, and intelligent control. It can handle complex terrain and easily cross misalignments, slopes, and steps exceeding 50mm. Its 8-wheel drive system and adaptive swaying head design ensure stable operation under various complex working conditions.
Multifit cleaning robots are equipped with advanced intelligent control systems, supporting WiFi/4G communication modules and cloud platform management for remote monitoring and fleet control. The robots feature an auto-sensing mode that automatically adjusts cleaning modes based on weather changes; they are equipped with a solar self-charging system that provides continuous power during cleaning, with operating time reaching 8-10 hours; edge detection and automatic obstacle avoidance functions ensure safe operation at the edges of PV arrays. Additionally, the company has launched the MR-T series tracked cleaning robots, MR-XY series vertical cleaning robots, and MR-AR series shuttle transfer vehicles, forming a complete portfolio of intelligent PV O&M solutions.
Global Project Footprint
Demonstrating strong global delivery capabilities and localized service levels.
