Hi-MO X10 HPBC 2.0 Module: LONGI Revolutionises Photovoltaics

Summary


In the increasingly competitive photovoltaic landscape, LONGi confirms its pioneering role with the launch of the updated Hi-MO X10 module, based on HPBC 2.0 technology. This upgrade, presented at the China (Jinan) International Solar Energy Utilisation Conference and discussed in depth at the TaiyangNews Reliable PV Module Design Conference 2024, introduces key innovations to improve performance, durability and safety, revolutionising industry standards.

The Three Key Innovations of HPBC 2.0

Anti-Dust 2.0: Maximising Energy Production

Dust accumulation is one of the biggest enemies of photovoltaic efficiency. LONGi has overcome dozens of technical difficulties, filing over 120 patents, to develop an advanced frame design that reduces particle sedimentation. Tests conducted by the National Photovoltaic Quality Inspection Centre (CPVT) from September 2023 to March 2024 show an average monthly energy gain of 2.33% compared to traditional BC modules, with daily peaks of over 10%.

Shade Tolerance and Fire Safety

Thanks to a structure similar to a bypass diode, the module minimises power losses in the event of partial shading (leaves, dirt, etc.). Under laboratory conditions, the temperature of the shaded cells remains below 80°C, compared to 130°C for TOPCon modules, reducing the risk of overheating and fire.

Fire Resistance: Integrated Protection

The materials and innovative design guarantee greater resistance to high temperatures, ensuring compliance with the most stringent safety standards.

Record Efficiency and Superior Performance

The Hi-MO X10 combines a maximum power output of 670 W with a conversion efficiency of 24.8%, exceeding conventional TOPCon modules by 10%. These results are made possible by HPBC 2.0 technology, which optimises light transmission and reduces energy losses.

Reliability at Every Stage of the Life Cycle

For Distributed Generation (DG) applications, where shadows, humidity and mechanical stress are critical issues, LONGi has integrated advanced solutions:

Hotspot mitigation:

Soft breakdown technology bypasses individual shaded cells, reducing power losses by 70% compared to TOPCon and keeping temperatures below 110°C.

Resistance to PID and UVID:

Uniform passivation on the front side and hybrid passivation on the rear side reduce UV degradation and current leakage, while materials such as high-density POE encapsulant counteract moisture.

Mechanical Strength:

TaiRay wafers, with a thickness greater than 10 µm and a 0BB (busbar-free) structure, increase resistance to breakage and micro-fractures by 16%, ensuring durability even in extreme conditions.

Validations and Global Success

LONGi subjected the modules to accelerated tests such as DH3000 (humidity and heat), UV180 (ultraviolet rays) and TC800 (thermal cycles), confirming their long-term reliability. With 30 GW of BC modules sold globally (including 10 GW for the commercial-industrial segment), the company is positioned as the market leader.

Conclusions: A More Efficient and Safer Future

The innovations introduced by LONGi in the Hi-MO X10 HPBC 2.0 not only raise the technical standards of photovoltaics, but also respond to concrete needs: maximising energy production, reducing maintenance and ensuring safety. As emphasised by Niu Yanyan, President of LONGi, and Dante Zeng, Product Marketing Manager, this module represents a strategic investment for those seeking reliable, high-performance solutions ready to dominate the distributed generation market.
With a winning combination of patents, partnerships and certified quality, LONGi confirms its leading role in the global energy transition.
