Li Shaotang, LONGi’s Product Marketing Director, detailed the HPDC-based Hi-MO 7’s main benefits during the unveiling. He stressed that LONGi Hi-MO 7 has been extensively examined, developed, and tested. Its high efficiency, world-leading product quality, and long-term dependability minimise the LCOE of large-scale solar projects in gobi-desert by enhancing energy generation output throughout the life cycle.
New HPDC cell technology boosts power generating efficiency “beyond imagination”
LONGi’s new Hi-MO 7 module, based on high-efficiency HPDC cell technology, is another “first principle thinking” innovation.
HPDC—High Performance and Hybrid Passivated Dual-Junction Cell—is another HPC cell technological improvement. High and low connections, optimised film design, and sophisticated deposition processes provide full-area passivation with minimum parasitic absorption on the cell backside. A local low-resistance contact layer improves cell efficiency on the front. Both sides have updated antireflection, low-recombination, and metallization films for better performance. The enhanced HPDC cell’s conversion efficiency, power temperature coefficient, and reliability can boost power generation improvements.
In the power generation demonstration project conducted by China National Electric Apparatus Research Institute Co., Ltd. in Qionghai, Hainan (on a high-albedo cement surface), Hi-MO 7 modules achieved a power generation gain of 2.9% compared to mainstream bifacial modules. This confirms that Hi-MO 7 outperforms similar products in temperature coefficient, low-irradiation and IAM performance, and product stability, making it more useful to ground power production terminal clients.
Multi-dimensional design ensures “more comprehensive” long-term value.
LONGi’s industry-leading product life cycle standards ensure Hi-MO 7’s dependability. High-quality monocrystalline silicon wafers, customised cell paste, optimised module encapsulation film system, SMBB high-precision interconnection, and high-reliability automatic welding of junction boxes make Hi-MO 7 reliable throughout its life cycle. Digitalized production and quality control systems, including sophisticated AI detection technologies, enhance Hi-MO 7 product quality. Thus, Hi-MO 7 offers a linear power warranty of 0.38%, delivering exceptional value and returns.
The LONGi Hi-MO 7 modules are big, high-efficiency bifacial modules that follow the M10 module dimension of 2278×1134 mm. LONGi and other businesses’ promotion of M10 helped the solar industry’s upstream and downstream understand the value and benefits of an acceptable module size. M10 has held over 70% market share for three years. Hard-won industry-wide standardisation. They can reduce product application risks in extreme weather, promote upstream-downstream coordination, facilitate photovoltaic power plant replacement and upgrade, and contribute to the industry’s healthy and sustainable development.
M10’s success was planned. Manufacturing, product reliability, application ease, and compatibility are balanced. Hi-MO 7, based on M10, works well with manual installation of huge racks, wires, and inverters. Module efficiency improvements can boost power station capacity by over 4.5% in a constrained space. This module reduces solar balance of system (BOS) expenses and AC terminal equipment prices, lowering power station operating and maintenance costs during its lifetime.
Top range of Hi-MO modules for terminal applications.
“No recklessness, no gambling” has guided LONGi’s photovoltaic technology and product innovations. After rigorous computation and verification, the product will be released to the market.
LONGi’s utility power station product range of “Hi-MO 5+Hi-MO 7” has improved with the launching of Hi-MO 7. Hi-MO 5 series, with its mature and reliable power generation performance that consistently exceeds customer expectations, will continue to dominate the utility market, while Hi-MO 7 series is best for modules with high ground surface reflectivity, elevated ambient temperatures, and limited land availability. LONGi’s Hi-MO 6 series, introduced last year, is a high-quality distributed generating device. Its efficiency, power output, and visual experience are unmatched.
The “Terawatt Era” and global carbon reduction have opened up endless solar industrial potential. Under progressively diverse solar application situations, the market demands solutions with improved efficiency, returns, and life cycle dependability. LONGi, a green energy company, will drive a zero-carbon future again with Hi-MO 7 and its more value Hi-MO series full-scenario products and solutions.
“Continuous and steady innovation is the key to LONGi’s consistent creation of higher market value,” stated Vice President Dennis She at the announcement. From promoting the technological revolution of monocrystalline industry to leading the large-scale application of PERC cell technology and bifacial dual-glass module technology, from promoting product size standardisation and rationalisation to the game-changing HPBC technology that reshapes value to the efficient empowerment of today’s HPDC technology, LONGi has driven the high-quality development of the solar industry with tech.
Innovating towards a green energy future. LONGi has driven industry growth with high-quality technological innovation for years. Over 100 GW Hi-MO modules have helped upgrade the worldwide energy system. According to LONGi’s latest annual report, LONGi supplied enough solar modules in 2022 to generate 46.76 GW, winning “three consecutive championships” in worldwide module delivery and market share. LONGi aims to deploy 85 GW of cells and modules (including self-use) by 2023. By year’s end, the newly launched Hi-MO 7 is scheduled to reach mass production with a capacity of 30 GW+. More profitable Hi-MO modules will help humans hasten a zero-carbon future.
