The company will showcase the new module and more at the RE+ tradeshow in Anaheim

SAN RAMON, Calif., September 20, 2022 /PRNewswire/ — LONGi, the leading solar technology company, announced today the launch of a new solar module specifically designed for residential and commercial applications in the US market. The new Hi-MO 5 54-cell module, based on the new market standard M10 182-mm-monocrystaline wafer, will be available in early 2023, first as a monofacial module with a bifacial module to follow later in the year . Based on the same technology used in the company’s popular large-format utility-scale 72-cell modules, the Hi-MO 5 54-cell module delivers superior power generation, reliable performance, high module efficiency and reduced system costs with an aesthetic appearance for rooftop distributed generation projects.

The Hi-MO 5 54-cell module has power outputs of up to 420 watts and a maximum efficiency of 21.5%. The monofacial module comes in a black design and has a 12-year warranty for materials and processing and a 25-year warranty for linear power output. The bifacial module will be a dual-glass design and have a 12-year warranty for materials and processing and a 30-year warranty for linear power output.

Weighing less than 50 lbs, the Hi-MO 5 54-cell can be handled and installed easily on roofs, and is compatible with standard module racking and mounting systems. With its optimized electrical parameters, the Hi-MO 5 54-cell is compatible with smart module-level power electronics (MLPE) devices such as Enphase microinverters and SolarEdge optimizers as well as mainstream string inverters.

LONGi’s Hi-MO 5 series won the 2021 Intersolar Award for advanced PERC gallium-doped p-type half-cut cell technology, smart soldering and other innovations, and earned “Top Performer” awards from RETC and others more independent labs. Hi-MO 5 modules have been delivered to more than 600 customers in more than 90 countries, with cumulative shipments of more than 30 gigawatts.

“We have strong customer interest in the new Hi-MO 5 54-cell module. Since its older brother the Hi-MO 5 72-cell module is our best-selling product for utility sector in the US, we expect very high demand for the new format,” said Aaron Thurlow, Head of Distributed Generation for LONGi Solar North America. “The full weight of LONGi’s advanced M10 technology, vertically integrated manufacturing, and financial stability stands behind the Hi-MO 5 54-cell product, making it one of the most promising distributed solar products LONGi has brought to the US market to date.This is another example of how LONGi is helping to drive the clean energy transition into the terawatt era.

In addition to the launch of the new module, the LONGi team will be out in full force at the upcoming RE+ tradeshow (formerly known as Solar Power International), which will take place.
