[Industry Insight] The Stock Asset Era Arrives: Solar Panel Cleaning Emerges as a New Value Driver
By 2026, China’s cumulative installed photovoltaic (PV) capacity has surpassed 1.25 billion kW, with solar power installations exceeding coal-fired power for the first time to become the cornerstone of the global energy transition. As large-scale wind and solar bases continue to come online and distributed PV projects under county-wide initiatives begin exiting warranty periods, the industry’s competitive focus is shifting from “scale and price” to “efficiency and operations.”
In post-construction plant management, dust accumulation, bird droppings, and industrial grime on module surfaces can cause annual generation losses of 5% to 30%, with desert and arid regions being particularly vulnerable. Industry analysis indicates that China’s PV O&M market grew by over 38% year-on-year in 2026. The penetration rate of intelligent O&M has risen significantly, and PV cleaning robots are rapidly transitioning from an “optional value-add” to a standard feature for utility-scale ground-mounted plants and premium C&I projects. Several leading cleaning robot manufacturers secured strategic cooperation agreements totaling over 10 GW, signaling the large-scale deployment of unmanned, water-saving/dry-cleaning, and integrated “cleaning + smart inspection” solutions.
Beijing MULTIFIT: 16 Years of Expertise in PV Storage & O&M—Ensuring No Sunlight Goes to Waste
Amid this surge in demand for refined O&M, Beijing Multifit Electrical Technology Co., Ltd. Which is leveraging its deep expertise in PV system design, inverter R&D, and EPC services to expand into intelligent PV module cleaning and full-lifecycle plant operations, offering global clients integrated “Solar + Storage + Smart Cleaning” solutions.
Core Cleaning & O&M Portfolio
Multifit’s proprietary MR-G Series PV Cleaning Robots and MULR Series Semi-Automatic Cleaning Brushes, featuring automatic deviation correction, obstacle crossing, and remote group control. These systems are adaptable to utility-scale plants, C&I color steel tile rooftops, and complex-tilt distributed systems. Field tests in high-wind, water-scarce regions such as Xinjiang and Qinghai confirm their effectiveness in restoring blocked module output, significantly boosting generation efficiency while reducing safety risks associated with manual cleaning.
Global Deployment Record
Overseas:
Multifit’s intelligent cleaning equipment and PV systems are exported to over 100 countries across Europe, the Middle East, Southeast Asia, and Africa. The company has supplied equipment for projects in Qatar and India, where the devices have demonstrated long-term stability in extreme desert heat and dusty conditions.
Domestic:
The company provides scheduled cleaning and O&M services for C&I rooftop PV, agrivoltaic complexes, and centralized power plants. These services integrate seamlessly with Multifit’s self-developed line-frequency/high-frequency inverters, MPPT controllers, and all-in-one storage systems to maximize asset value throughout the project lifecycle.
“Half the value of a PV asset lies in its construction, and the other half in its maintenance,” noted a Multifit spokesperson. “We aim to recover the generation capacity ‘stolen’ by dust through reliable cleaning robots and standardized O&M protocols.”
Looking ahead, Multifit will continue to enhance the AI perception capabilities of its cleaning robots and cloud platform integration, helping global green energy assets achieve superior LCOE (Levelized Cost of Energy) competitiveness.
