With the Ministry of Industry and Information Technology’s (MIIT) electronics industry standard SJ/T 12055-2025 “Technical Specifications for Photovoltaic Module Cleaning Robots” officially implemented on July 1, 2026, China’s PV cleaning robot sector has finalized its “triple-standard” framework: General National Standard → Dry-Cleaning Specific Standard → Comprehensive Electronics Industry Standard. This niche equipment segment, long plagued by a lack of standards and cut-throat competition from inferior products, now formally enters a new stage of compliance and quality enhancement.
Dust accumulation on PV modules consumes 4%-7% of global annual power generation. Domestically, demand for “water-efficient, high-efficiency cleaning” is surging across desert and Gobi bases, while overseas markets—particularly the Middle East—require similar solutions. Previously, the absence of unified thresholds allowed low-cost equipment to damage anti-reflective coatings and degrade module performance.
GB/T 44264-2024 “General Technical Requirements for Photovoltaic Module Cleaning Robots” (Effective March 1, 2025): This foundational national standard defines classifications, dust removal rates, obstacle-crossing stability, and IP protection levels, establishing universal baseline requirements.
NB/T 11903.1-2025 “Technical Specifications for Dry-Cleaning Robots” (Effective June 18, 2026): This energy industry standard locks in the mainstream “waterless dry-cleaning” track, aligning perfectly with water-scarce scenarios in desert/Gobi regions and international markets.
SJ/T 12055-2025 “Technical Specifications for Photovoltaic Module Cleaning Robots” (Effective July 1, 2026): This MIIT electronics industry standard covers the entire chain—from classification structures and technical requirements to testing methods and inspection rules—forming a complete closed loop with the aforementioned standards.
Industry Impact: Non-compliant, “unregulated” equipment from lesser-known brands is rapidly exiting the market. Power generation groups now have strict hard-entry criteria for procurement, while leading enterprises with substantial R&D capabilities stand to gain significant dividends from this standardization.
Multifit: 17-Year PV Cleaning OEM Aligns Full-Scenario Robotics with National Standards
Amidst this new compliance cycle, Beijing Multifit electrical Technology Co., Ltd—a National High-Tech Enterprise established in 2009, recognized as a Guangdong Provincial “SRDI” (Specialized, Refined, Unique, Innovative) SME, and a Shantou “Gazelle” enterprise—is meeting these new standards head-on with its identity as a “source manufacturer plus full-scenario portfolio.
Multifit has specialized in PV cleaning robots and new energy electrical systems for 17 years. Headquartered in Beijing with a manufacturing base in Shantou, Guangdong, the company holds over 60 patents and maintains CE/FCC/ISO certifications. Its products are exported to more than 50 countries across Europe, the Americas, the Middle East, Asia, Africa, and Latin America:
Fully Automatic Portfolio: MR-G3 hanging-type waterless cleaning robot (self-powered, adapted for water-scarce plants), MR-T1 AI path-following robot, left-right/up-down transfer vehicles, and shuttle transporters;
Semi-Automatic Equipment & Brushes: MULR series soft-bristle brushes supporting dual-mode dry/wet cleaning, designed to prevent coating scratches;
Intelligent Platform: Remote cloud control, automatic posture correction, 50mm obstacle crossing, and swarm scheduling capabilities, covering large-scale ground stations, rooftop distributed projects, and overseas desert/Gobi installations.
Aligning with the triple standards’ requirements for “dust removal rates, dry-cleaning adaptability, and module safety,” Multifit is conducting comprehensive self-inspections of its hanging-type and dry-cleaning robots against GB/T 44264 and NB/T 11903 specifications. Leveraging its MR-G3 waterless solution, the company is penetrating essential overseas markets such as the Middle East and Australia—shifting from “selling equipment” to “selling compliant power generation assurance“—facilitating a steady expansion into international markets during this new era of standardized compliance.
