LONGi Sets a New Benchmark in Solar Efficiency with the Next‑Generation Hi‑MO S10 Modules

LONGi continues to push the boundaries of photovoltaic innovation with its latest Hi‑MO S10, engineered to deliver superior efficiency, reliability, and long-term energy yield for utility-scale and distributed generation projects.

Designed with advanced cell architecture and cutting-edge module engineering, the Hi‑MO S10 achieves an industry-leading module efficiency of up to 25.4%, positioning it among the most powerful high-efficiency solar modules available in the market today. This exceptional performance is enabled by LONGi’s proprietary Hybrid Interdigitated Back Contact (HIBC) technology, which enhances light absorption and minimizes resistive losses, resulting in higher energy generation across diverse operating conditions.

A key advantage of the Hi‑MO S10 lies in its enhanced energy yield and reliability. The module delivers a power output range of 665W to 685W, ensuring optimal performance for large-scale solar installations where maximizing output per square meter is critical. Additionally, the module features bifacial capability with up to 60% ±5% bifaciality, enabling increased rear-side energy generation and improved overall system efficiency, particularly in high-albedo environments.

LONGi has also prioritized durability and long-term performance in the Hi MO S10 design. The module demonstrates less than 1% degradation in the first year and a remarkably low annual degradation rate of just 0.35% from year 2 to 30, ensuring consistent power output over its lifecycle. Backed by a 15-year product warranty and a 30-year linear power output warranty, the module provides investors and developers with long-term confidence and reduced levelized cost of energy (LCOE).

From a mechanical and environmental standpoint, the Hi‑MO S10 modules are built to withstand challenging conditions. Featuring a dual-glass structure (2.0mm + 2.0mm semi-tempered glass) and an anodized aluminum alloy frame, the modules offer enhanced protection against environmental stress. They can handle front-side static loads up to 5400Pa and rear-side loads up to 2400Pa, along with resistance to hail impact, making them suitable for deployment in diverse climatic regions.

The module’s optimized anti-shading design further enhances performance by reducing mismatch losses and preventing localized overheating, ensuring stable operation even in partially shaded conditions. Additionally, its lower operating temperature characteristics contribute to improved efficiency and system longevity, particularly in high-temperature environments.

With a maximum system voltage of 1500V DC and compatibility with modern high-power inverters, the Hi‑MO S10 series is well-suited for next-generation solar systems. Its robust design, combined with international certifications including IEC and ISO standards, underscores LONGi’s commitment to quality, safety, and sustainability.

Through the introduction of the Hi MO S10, LONGi reinforces its leadership in delivering high-performance solar solutions that meet the evolving demands of the global energy transition. This latest innovation reflects the company’s continued focus on maximizing energy yield, enhancing system reliability, and driving down the overall cost of solar power generation worldwide.
