The LONGi Hi-MO X10 is a premium solar panel product built on advanced HPBC 2.0 cell technology. It delivers strong power generation performance, high reliability, and long-term customer value. Designed to meet the needs of distributed solar market segments, the Hi-MO X10 is available in four series: Explorer, Scientist, Guardian, and Artist, making it a high-value solution for modern solar systems. .

HPBC 2.0 is the second generation of Hybrid Passivation Back Contact cell technology independently developed by LONGi. It builds on the proven foundation of HPBC 1.0 and is based on a high-end BC technology platform. A key feature is the absence of grid lines on the front side, which improves light absorption and power output. This advanced solar cell technology is the result of comprehensive optimization of cell substrates, hybrid passivation, and manufacturing processes. Its performance, reliability, and functionality are significantly enhanced compared to mainstream solar cells in the market. HPBC 2.0 represents a major step forward in BC cell development. It can be defined by the formula. HPBC 2.0 equals BC multiplied by Bipolar Hybrid Passivation multiplied by TaiRay Wafer multiplied by 0BB structure. .

HPBC 2.0 builds on the proven foundation of HPBC 1.0 cell technology and delivers major improvements across three core technical areas. These advances result in a significant increase in solar cell performance. HPBC 2.0 has achieved a mass production efficiency of 26.6%, which is currently the highest among commercially produced solar cell technologies. In silicon substrates, HPBC 2.0 uses LONGi’s high quality TaiRay N-type silicon wafers. This improves efficiency potential, reduces degradation, and enhances resistance control. In passivation technology, HPBC 2.0 upgrades the hybrid passivation system to Bipolar Hybrid Passivation. This reduces recombination and increases open circuit voltage. In process technology, HPBC 2.0 introduces the 0BB structure, which shortens current transmission distance by 6.5% and increases module power by around 5W. High precision laser etching and insulating material printing further improve electrical safety and transmission performance.

The LONGi Hi-MO X10 solar panels are built around four core values. Advanced, value added, aesthetic, and safe. Advanced Hi-MO X10 uses HPBC 2.0 cell technology, which is the most efficient solar cell technology currently in mass production. Cell efficiency exceeds 26.6%, while module efficiency reaches 24.8%. Power generation per unit area increases by more than 5 percent compared to TOPCon. Based on the BC cell platform, Hi-MO X10 combines TaiRay wafers, bipolar hybrid passivation, and 0BB zero busbar technology. Nearly 200 patented technologies contribute to stronger and more stable power generation. Value added Hi-MO X10 modules deliver around 30W more power than comparable TOPCon modules. Each module can generate more than 60 kWh of additional electricity per year. Over a 30 year lifecycle, this results in significant long term value. The additional investment per module is low and can be recovered within a short operating period, making Hi-MO X10 a high return solar panel solution. Aesthetic The front side has no visible grid lines, creating a clean and flawless black appearance. The design aligns with modern architectural styles and integrates naturally with different building environments. Safe Hi-MO X10 features a soft breakdown design that reduces the risk of hot spots under shading conditions. This improves operational safety and helps prevent fire risks. High strength TaiRay wafers combined with flat welding tape technology reduce stress and minimize the risk of micro cracks. Enhanced full lifecycle testing supports long term product safety and reliability, with up to 30 years of power warranty..

Using the 72 cell version as an example, the Hi-MO X10 solar panel has a module size of 2382 × 1134 × 30 mm. The maximum module power reaches 670W, with a peak efficiency of 24.8%. First year power degradation is 1%, followed by a linear degradation rate of 0.35% per year. The power temperature coefficient is −0.26% per degree Celsius. In mass production, Hi-MO X10 delivers an average of around 30W higher output compared to mainstream TOPCon solar panels. This positions it as one of the highest efficiency mass produced solar modules currently available.

The Hi-MO X10 solar panel delivers customer value across safety, power generation, and design. Ultimate safety Hi-MO X10 uses a unique soft breakdown design that significantly lowers hot spot temperatures under shading conditions. Compared to conventional solar cells, hot spot temperatures are reduced by more than 28%, lowering the risk of module failure. Its low operating temperature and high density packaging perform strongly in UV exposure, humidity, and thermal cycling tests, exceeding the performance of TOPCon cells. High thickness TaiRay silicon wafers combined with full back welding improve resistance to hidden cracks and enhance long term structural reliability. Higher power generation Hi-MO X10 achieves a mass production power output of up to 670W with a module efficiency of 24.8%. This is around 30W higher than mainstream TOPCon solar panels. Its anti shading capability reduces power loss by more than 70 percent under partial shading conditions. The 0BB structure further improves cell efficiency potential, increasing module power by about 5W. Optimized temperature coefficient and degradation performance at −0.26% per degree Celsius and 0.35% linear degradation support higher long term energy output. Under limited installation space, this results in greater capacity, higher electricity generation, and improved economic returns. Global simulation data shows power generation gains of up to 8.7% compared to TOPCon. Minimalist aesthetics Hi-MO X10 continues the clean aesthetic of BC solar cell design with no visible grid lines on the front surface. The result is a simple and refined appearance that integrates naturally with building architecture. The 0BB structure removes busbars on the back side as well, improving both visual consistency and bifacial performance potential. This design supports future development of advanced double sided solar modules.
