Introduction about Hi-MO X6 Max
1) What is the Hi-MO X6 Max series? What are the products in this series?
Hi-MO X6 Max follows the Hi-MO X6 product family categorization, and the full range of products includes 4 series: Hi-MO X6 Max Explorer, Hi-MO X6 Max Scientist, Hi-MO X6 Max Guardian, and Hi-MO X6 Max Artist.
Among them, the Guardian series has now launched two specific functional models, Hi-MO X6 Max Guardian (Anti-dust design) and Hi-MO X6 Max Guardian (Anti-humidity&heat design); the Artist series has not yet been switched, and will be switched to the new sizes in the future as well.
2) What are the advantages of Hi-MO X6 Max?
“Three Highs” + ”Three New” + Lower attenuation, higher intensity, higher efficiency
New technology: TaiRay Inside stacked HPBC high-efficiency cell technology, first decay reduced to 1%, power temperature coefficient optimized to -0.28%/°C, maximum module efficiency increased by 0.1%, PID attenuation greatly optimized, hidden crack probability reduced by 80%+;
New size: According to the industry standardization agreement led by LONGi, Hi-MO X6 Max is equipped with M11 size wafers for the first time, with the 72c module size updated to 2382*1134mm and the 54c module size updated to 1800*1134mm, which reduces industry chain costs and upstream and downstream risks; after the size upgrade, customer costs such as module transportation costs and BOS costs are significantly reduced, while Compared with competing 210R wafer module products, the DC line loss is reduced and power generation is improved, and the reliability performance is also better;
New products: Hi-MO X6 Max has four major product series (Explorer/Scientist/Guardian/Artist), of which the Guardian series has launched two functional models of anti-dust accumulation design and humidity and heat resistance design, which can provide more choices for users' differentiated needs. The entire product family has three core universal value features, namely high quality/high technology/high reliability.
High quality: Hi-MO X6 Max selects raw materials and upgrades product performance with innovative technologies such as HPBC and TaiRay Inside to provide stronger power generation performance and bring users higher quality products.
High Reliability: LONGi has its own production and quality control system to ensure the robustness and reliability of the modules through strict monitoring of incoming materials, tracking of the production process, and rigorous testing with authoritative approval before the modules leave the factory.
High-tech: Technology is used to realize the aesthetic appearance of the modules, technology is used to enable the fulfillment of the pain points of specific scenarios, and technology is used to ensure the lean manufacturing of the whole process of the products.
First-year attenuation and power temperature coefficient: TaiRay Inside reduces the impurity content of silicon wafers through good impurity-absorption process, which improves the lifetime of minority carrier by more than 10%, and combines with Longi's self-developed composite passivation process, which reduces the composite current by more than 50% compared with TOPCon, and the combination of these two processes ultimately realizes the first-year attenuation of power generation of the module to be reduced from 1.5% to 1%, and the power temperature coefficient optimized to be reduced from -0.29%/℃ to -0.28%/℃. The power temperature coefficient is optimized from -0.29%/°C to -0.28%/°C, which comprehensively improves the electrical performance of the module.
Greater mechanical strength of the module: By optimizing the ratio and process of doping elements in silicon wafers, TaiRay Inside has increased the mechanical strength of silicon wafers by 16%, and superimposed with the special BC zigzag welding structure, it can effectively reduce the force transmission when subjected to edge stress. Compared with the Z-shaped welding of non-BC cells of friends, it reduces the edge stress by 48%, and the superposition of the two makes the risk of hidden cracks in the module significantly lower. Based on the data from LONGi's logistics service department and testing department, Hi-MO X6 Max modules can effectively reduce the risk of hidden cracks by more than 80% compared with conventional modules.
Higher module efficiency: Compared with conventional double-sided electrode cells, no leakage channels are formed on the upper surface, which reduces the overall PID attenuation of the module, and due to the concentration of resistivity, the maximum efficiency of the module's 72 version is increased from 23.2% to 23.3%.
Hi-MO X6 Max vs. Hi-MO X6 comparison related:
1) What is the relationship between Hi-MO X6 and Hi-MO X6 Max?
Hi-MO X6 Max is a product upgrade of the existing Hi-MO X6, which takes over the core technology of HPBC batteries and carries the new LONGi TaiRay Inside technology, leading the industry size standard and refreshing the four major product families, which can better satisfy the needs of distributed customers and continue to lead the development of distributed PV in the world.
Hi-MO X6 Max series products have been upgraded in three directions compared to Hi-MO X6: new technology, new size and new products.
New Technology: TaiRay Inside Technology, stacked with HPBC high-efficiency battery technology.
New Size: M11 size wafers are equipped for the first time, 72c module size is updated to 2382*1134mm, 54c module size is updated to 1800*1134mm.
New products: Hi-MO X6 Max Explorer, Hi-MO X6 Max Scientist, Hi-MO X6 Max Guardian, Hi-MO X6 Max Artist. Among them, the Guardian Home series has been launched with two functional models, the anti-dust accumulation design and the humidity and heat resistant design, which can provide more choices for users' differentiated needs.
2) What sizes have been switched for Hi-MO X6 Max? What is the size after switching?
The built-in wafer size has been switched, and the entire module size has also been switched and upgraded. The first M11 wafer size is (182.2mm*191.6mm), the 72c module size is updated to 2382*1134mm, and the 54c module size is updated to 1800*1134mm.
3) Why switch size?
LONGi has always taken customer value as the core, and after gaining insights and conducting in-depth research on the needs of customers in the distributed business, LONGi found that different module and cell sizes in the industry would increase the cost and risk of the upstream and downstream industry chains. In order to better serve our customers, reduce their costs and increase their revenues, LONGi, together with eight leading PV companies (JinkoSolar, JA Solar, Trina Solar, GCL, TONGWEI, Astronergy,Risen Energy, and Together with DAS Solar), reached an agreement to standardize the size of the 72-version modules (2,382*1,134mm) and the size of the M11 wafers (191.6*182.2mm) by the end of the Q3 of 2023. 191.6*182.2mm standardization unification agreement, is the result of collective decision-making and joint professional research and judgment. Finally, on May 23, 2024, LONGi released Hi-MO X6 Max, a standardized module product based on M11 wafers and 2382*1134mm size switching, and effectively promoted the synergy of production, supply and marketing, and started the switching in Q2 2024, and completed the upgrading of all the mainstream products in Q3 24 years.
4) What are the benefits brought by the switchover?
1. Higher power generation:
Taking the 72 version as an example, compared with the same module specification products of friends using 210R wafers, Hi-MO X6 Max module products using M11 wafers have lower current, which can effectively reduce current transmission cable loss by 9%, and enhance power generation gain by 0.1%.
2. Lower cost
Lower transportation cost: Taking the 72 version as an example, the container utilization rate of Hi-MO X6 Max module reaches 98.5%, which is 4.4% higher than that of M10, and can effectively reduce the transportation cost by about 0.44 cents/W.
System Cost Reduction: Take the 72 version as an example, under the same roof area, the BOS cost at the installation end of the system is reduced by 3.57% (about 3 cents/W).
