LONGi has introduced the Hi-MO X10 Light Design Module, an innovative solution aimed at tackling one of the primary obstacles to solar energy adoption: the limitations of rooftop load. Despite the increasing global demand for solar energy, over 30% of rooftops are still deemed unsuitable for panel installation due to structural load constraints, preventing many owners from pursuing clean energy options due to the high costs of reinforcement. The Hi-MO X10 Light specifically addresses this issue, making solar energy feasible for low-load commercial and industrial (C&I) rooftops. Jiang Dongyu, President of LONGi’s Distributed Business Group, emphasized that LONGi remains committed to the principles of stability, reliability, and technological leadership, even amid the industry’s push for cost reductions.
“When the need for cost savings conflicts with product reliability, LONGi will always prioritize reliability,” stated Jiang Dongyu.
Leveraging LONGi’s advanced HPBC 2.0 cell technology, the Hi-MO X10 Light achieves industry-leading performance, boasting an efficiency of up to 24.8% and a maximum output of 560W. Weighing in at just 7.2 kg/m², it is more than 30% lighter than conventional modules, setting a new standard for lightweight, high-efficiency solar solutions. The product was initially launched in China in May 2025 and is now expanding into global markets.
Advantages of Lightweight Design
The module’s optimized structure reduces rooftop load by 42% compared to traditional dual-glass TOPCon modules. For instance, a 10,000 m² rooftop can experience a load reduction of 34 tons. This breakthrough could potentially make over 1 billion square meters of industrial rooftops globally accessible to solar energy.
Cost Efficiency and Performance
With a conversion efficiency of 24.8% significantly higher than the typical 21.6% of similar products the Hi-MO X10 Light generates 140W more per module than other lightweight alternatives. This not only enhances system output but also reduces balance-of-system (BOS) costs by up to 33%. By eliminating the need for costly rooftop reinforcements, which can exceed 0.5 RMB/W in China, the module makes solar adoption much more affordable. Additionally, installation time is significantly reduced from over 40 days to just 8–10 days, minimizing disruptions to factory operations.
Strength and Durability
Despite its lightweight design, the Hi-MO X10 Light is built to be highly durable. A one-line welding ribbon on the back improves load distribution, increasing the bearing capacity by over 50% and reducing central deformation by 50%. The reinforced frame, which is 5% thicker and structurally optimized, enhances overall strength by 20%, providing greater resilience against strong winds and heavy snowfall.
