Delivers more than 2% increase in power generation per watt through advanced anti dust design. Reduces cleaning frequency by up to two times per year, lowering O&M costs and water use. Hi MO 9 secures industry first full scenario reliability certification under IEC 63556.
Chinese solar manufacturer LONGi has introduced its Hi MO X10 Anti Dust Pro module, engineered to address one of the most persistent challenges facing utility scale solar projects in desert and arid regions, dust accumulation.
The new module incorporates advanced dust resistant glass and a short edge frame design without an A surface, reducing the build up of dust and snow while enhancing light capture. By minimising surface soiling, the technology maintains more stable performance and delivers more than a 2% increase in power generation per watt, supporting higher long term energy yield in high soiling environments.
Designed for extreme climatic conditions, the Hi MO X10 Anti Dust Pro combines the company’s latest high efficiency cell architecture with an innovative surface treatment that reduces ongoing operational demands. Cleaning frequency can be reduced by up to two times per year, significantly lowering O&M costs and improving project cash flow, particularly for large scale plants in remote desert locations where logistics and water access remain key constraints.

Lower cleaning requirements also translate into reduced water consumption, aligning the solution with sustainability objectives in water scarce markets across Africa and the Middle East. For developers and independent power producers operating in arid climates, the reduction in both resource use and maintenance interventions enhances overall project bankability.
The product was officially launched at the World Future Energy Summit 2026, underlining LONGi’s strategy to deliver high performance, reliable technologies that strengthen the business case for solar in challenging operating environments.
In related developments, LONGi announced that its HPBC 2.0 based Hi MO 9 module has successfully passed more than 40 full scenario test sequences covering lakes, deserts, ice and snow, and marine environments. The module received the Full Scenario Application Certificate under the IEC 63556 standard from the National Quality Inspection and Testing Center for Solar Photovoltaic Products and the Huaneng Clean Energy Research Institute.
As the photovoltaic sector’s first certification focused on module reliability across all scenarios, the recognition confirms the ability of the Hi MO 9 platform to maintain efficient and stable power generation in complex and rapidly changing environmental conditions. The milestone further consolidates LONGi’s position as a key technology partner in the global energy transition, setting new benchmarks for efficiency, durability and innovation in the solar industry.
