Could 25, 2023 Vincent Shaw

Chinese language photo voltaic module maker Longi unveiled this week its new Hello-Mo 7 PV module for giant scale and C&I purposes on the SNEC tradeshow in Shanghai, China.

The producer mentioned the brand new product relies on tunnel oxide passivated contact (TOPCon) cells, M10 wafers and high-performance hybrid passivity (HPDC) twin junction expertise.

“The bottom of the cell options excessive and low junctions, optimized movie design, and superior deposition strategies to realize exceptional full-area passivation with minimal parasitic absorption,” the corporate defined. “On the entrance facet, the cell is utilized with an area low-resistance contact layer that enhances cell effectivity. Moreover, each the back and front sides incorporate upgraded antireflection and low-recombination movies, in addition to metallization options, for superior efficiency.”

The brand new product measures 2,278 mm x 1,134 mm x 30 mm and has a weight of 31.8 kg. It options 2.0 mm twin glass, an anodized aluminum body, and an IP68 score. The temperature coefficient is -0.28% per C.

The brand new collection is available in seven variations, with energy outputs between 560 W and 590 W. The ability conversion effectivity ranges between 21.7% and 22.8%. The open-circuit voltage ranges from 50.89 V to 51.63 V and the short-circuit present is between 13.89 A and 14.1 38.

The panels can be utilized in PV programs with a most voltage of 1,500 V. The corporate affords a 12-year product assure and 30-year energy output assure for 88.18% of the preliminary yield.

“Longi’s industry-leading product life cycle requirements additionally assure the reliability of Hello-MO 7. Hello-MO 7 successfully ensures its reliability all through its life cycle with optimized designs akin to high-quality monocrystalline silicon wafers, custom-made cell paste, optimized module encapsulation movie system, SMBB high-precision interconnection, and high-reliability computerized welding of junction containers,” the producer said.

“The appliance of digitalized manufacturing and high quality management platforms, particularly clever AI detection expertise, additional ensures the product high quality of Hello-MO 7. Subsequently, Hello-MO 7 gives a linear energy guarantee of no more than 0.38%, bringing prospects sturdy worth and environment friendly returns past expectations,” it added.
