LONGi, a global solar technology leader, launches its next generation high-end back contact solar module to the French and Belgian markets at EnerGa?a, a leading renewable energy trade show in Montpellier, France.?Based on LONGi's new HPBC 2.0 technology, the Hi-MO X10 is equipped with the company's new proprietary n-type TaiRay wafer and bipolar hybrid passivation technology, which brings significant improvements in efficiency, mechanical characteristics and reliability. In addition, it comes with 0BB-structure (zero-busbar), a multi-layer design for increased performance, as well as a shading optimizer technology that reduces the loss of power output by 70% compared to TOPcon modules. Overall, the Hi-MO X10 sets a new performance benchmark with 670W output power, 24.8% module efficiency and 26.6% cell efficiency. It outperforms conventional TOPCon modules by 30W. LONGi aims to achieve approximately 50GW of HPBC 2.0 module production capacity by the end of 2025.
In France the Hi-MO X10 product series will be available from Q2 2025, starting with a 54-cell single glass product and a 72-cell dual glass product. In Belgium, the 72-cell dual-glass product will be launched as early as March 2025, followed by a full black 54-cell single glass product in Q2 2025.?
Hi-MO X10 – Engineered to maximize reliability, cost-effectiveness, and long-lasting power output
With only 1% degradation in the first year and an annual linear degradation rate of 0.35%, the module offers unmatched longevity. In addition, its power temperature coefficient of -0.26%/°C delivers a 0.03% improvement over TOPCon modules, ensuring superior performance especially in hot climates.?
HPBC 2.0 (Hybrid Passivated Back Contact Technology) enhances solar module efficiency and reliability through a multi-layer structure designed for optimal performance:?
The zero-busbar structure significantly changes cell design and performance?
The back contact manufacturing process has been upgraded through the implementation of a zero busbar (0BB) structure utilizing an intelligent soldering process to make the connections stronger than with conventional soldering. By directly connecting the ribbons to the fingers the energy transmission distance is reduced by 6.5%, adding an extra 5W to the module’s power output. This changed back contact structure also removes the shading of the busbars, enhancing aesthetics as well as its performance. Precision laser etching and advanced high transparency insulating materials further enhance performance by reducing leakage risks and improving light absorption.
LONGi’s TaiRay wafer drives a higher reliability and performance directly at the core of the modules?
LONGi’s proprietary TaiRay wafer solves the long-standing challenges of silicon wafer limitations. With improved resistance distribution, fewer impurities, and a remarkable 16% increase in break resistance, this wafer is a key driver of the Hi-MO X10’s high performance. The performance increase and associated benefits are the result of an enhanced Recharge Czochralski (RCz) process (crystal pulling method) used in the production of monocrystalline silicon ingots.?
The Hi-MO X10 module series is highly qualified for all the different PV scenarios and regions in France?
Hugo Fernandez, General Manager for Spain, Portugal and France is recommending the Hi-MO X10 for France: "The new Hi-MO X10 with second-generation HPBC back-contact technology is well suited to the diverse needs of the French commercial, industrial and residential PV markets. Compared to technologies such as TOPCon, it delivers an average of 1.5% higher efficiency, resulting in approximately 30W of additional power per module. The Hi-MO X10 also operates at lower temperatures and offers excellent resistance to aging, ensuring reliable performance in France's diverse climatic conditions, from the sunnier southern regions to the cooler and cloudier north.??
A key innovation is the integration of 0BB (zero busbar) technology into back-contact modules, an industry first. This design optimizes energy capture by increasing sunlight absorption on the cell surface, improving efficiency not only during peak sunlight hours but also in diffuse light conditions such as those experienced in northern France or during cloudy weather. In addition, the module is highly adaptable to rooftop and ground-mounted installations, which are common in various regions of France.??
With its ability to deliver consistently high yields and a lower levelized cost of electricity (LCOE), the Hi-MO X10 is a versatile and reliable solution for maximizing long-term energy production in France's diverse PV landscape."?
The Hi-MO X10 module series is designed to meet the high security requirements of the Belgian market?
LONGi also launched the Hi-MO X10 for the Belgian market during the EnerGa?a trade fair in France. The module will be available in 72 and 54 cell sizes from March and is designed to meet customers' stringent safety requirements for solar modules.?
Linda Huang, General Manager of the Benelux Representative Office, on the Hi-MO X10 for the Belgian market: "Hi-MO X10 distinguishes itself in the market by excelling in four critical areas: captivating aesthetics, unwavering reliability, robust performance, and unparalleled value. Historically, the industry faced a challenging trade-off between high power output and safety concerns, particularly regarding fire risks. Hi-MO X10 shatters this paradigm, offering a comprehensive solution that delivers exceptional results across multiple dimensions without significant compromises. This groundbreaking product empowers customers with a well-rounded package that seamlessly integrates power, safety, and efficiency.??
In addition, Belgians take special interest in aesthetics and performance in solar energy installations. Solar panels, as visible elements on rooftops or fa?ades, are expected to blend seamlessly with traditional or modern home design in Belgium, adding to the overall aesthetic harmony. The Hi-MO X10 is the ideal solution for this. Its HPBC 2.0 back contact technology is unparalleled in its ability to cater to this specific need.”?
HPBC 2.0 is the start of a new era in back contact technology?
LONGi’s HPBC 2.0 technology represents a leap forward in back contact solar modules, overcoming previous limitations in back contact (BC) cell design and silicon wafer constraints. One of the major advances made by LONGi’s R&D between HPBC 1.0 and 2.0 is the 1% increase in cell efficiency in only 2 years of development from 2022 to 2024. Another important step was LONGi’s switch from P-Type to N-Type wafers.?
LONGi's commitment to research and development to further improve its back contact technology continues unabated, resulting in multiple records in 2024. The latest record from October 2024 is particularly significant as LONGi is the first Chinese solar technology company to break the world module efficiency record since its first recording in 1988. LONGi now tops the world module efficiency record list with 25.4%. The National Renewable Energy Laboratory (NREL) has updated its Champion Photovoltaic Module Efficiency Chart accordingly: https://www.nrel.gov/pv/module-efficiency.html?
In May 2024, LONGi made history when its heterojunction back contact (HBC) solar cell achieved a new world record for photovoltaic conversion efficiency of 27.3%, certified by the Institute for Solar Energy Research Hamelin (ISFH).??
The Hi-MOX10 will be available in 72 and 54-cell product versions.??
