Core Advantages

Smart Soldering

Uniform smart soldering increases the power and efficiency of the module, and improves the power load capacity.

Optimized Electrical Parameters

The working current is about 13A, which is perfectly adapted to mainstream string inverters.

Optimized Module Size

Large-format modules with M10 wafer size use dual-glass and frame packaging to ensure module strength.

Gallium-doped Technology

Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module.

Smart Module Packaging and Logistics

Smart module packaging solutions are used to achieve high reliability, low-cost transportation and logistics.
 

Bifacial Energy Yield

Additional power generation from the backside of bifacial modules increases the overall energy yield, which has been verified by customers and third-party testing organizations.
 

    FAQs

    What are LONGi's module products and what applications are they suited for?
    • LONGi has two series of solar module products: Hi-MO 4, Hi-MO 5. and each series contains bifacial and monofacial module. Hi-MO 4 and 54-cell type Hi-MO 5m is mainly used on industrial, commercial and residential roofs. Both bifacial and monofaical of Hi-MO 5 with 72-cell is mainly for large ground-mount power plants.
    What are the advantages of Hi-MO 5 in ground-mount power plants?
      • Because of its high power rating and efficiency, Hi-MO 5 can be more cost-effective in terms of BOS. Hi-MO 5 can increase the power of a single string and thus increase the plant’s DC:AC ratio when using string inverters, which can reduce the cost of electrical equipment and thus reduce the LCOE. In addition, Hi-MO 5 can reduce the cost of module logistics due to its higher utilization of container space.
      •  
    Why does LONGi choose 182 mm wafer size in the design of Hi-MO 5 ?
      • LONGi analyzed various boundary conditions involved in module manufacturing and system applications, from production feasibility, module reliability, application compatibility to transportation and manual installation, and finally determined that 182 mm silicon wafers and modules were the best configuration for large-format modules. We believe that the size of a 182 mm module does not have major mechanical load and reliability consequences, Further size increasing of module will not bring value in manufacturing cost or system cost reduction, but increase reliability risks.During transportation, the 182 mm module can maximize the use of shipping containers and reduce transportation costs. We believe that the size of a 182 mm module does not have major mechanical load and reliability consequences, and any increase in module size may bring reliability risks.
      •  
    What type of module is better for my application, monofacial or bifacial?
    • Bifacial modules are slightly more expensive than monofacial modules, but can generate more power under the right conditions. When the rear side of the module is not blocked, the light received by the rear side of the bifacial module can significantly improve energy yield. In addition, the glass-glass encapsulation structure of the bifacial module has better resistance to environmental erosion by water vapor, salt-air fog, etc. Monofacial modules are more suitable for installations in mountainous regions and distributed generation rooftop applications.
    •  
    What are other advantages of LONGi bifacial modules?
    • LONGi took the lead in working with domestic and foreign institutions and customers to carry out empirical testing of bifacial modules for PV power plants, systematically studying the power generation mechanisms of bifacial modules. LONGi also leads the industry in bifacial module shipments, surpassing 20 GW+ , while providing customers with reference data and technical support.
    •  
    How does LONGi guarantee module supply?
    • LONGi has the largest module production capacity in the industry, with more than 65 GW in its integrated capacity network fully guaranteeing the supply of modules. In addition, the production network facilitates the global distribution of modules with the help of land transportation, railway transportation and sea transportation.
    •  
    How does LONGi ensure module product quality?
    • LONGi launched Life-cycle Standards to guarantee the whole life-cycel quality.LONGi's Integrated capacity layout can guarantee the traceability of each module, and our highly automated production lines feature end-to-end inspection and analysis processes to ensure that each module meets the highest quality standards. We select module materials according to the highest standards, with the requirement that all new materials be subject to extended qualification and reliability tests before being incorporated into our products. Third-party labs like RETC and PVEL have ranked our modules among the highest quality products on the market.
