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.
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 the advantages of Hi-MO 5m 54c in the DG market?
Hi-MO 54c has an industry standardized size, which is conducive to the system costs caused by the standardization of brackets and inverters. The size and weight of module are suitable for single person handling, and the operation and installation are convenient, and it is perfectly suitable for 15A string inverter.
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.
