LONGi upgrades its bifacial Hi-MO 7 module, increasing its value

Following the launch of the LONGi Hi-MO 7 bifacial module in May 2023, LONGi is building on its success by launching a new, higher-performance version of the module – available exclusively in Canada. The module upgrade features improved aesthetics with a darker, more elegant look and is a response to both customer demand for greater power capacity and updated industry standardization of module dimensions.

The first version of the Hi-MO 7 module represented a significant advance in solar technology, combining efficiency, reliability and sustainability. The improved Hi-MO 7 module continues to use the high-efficiency cell technology and now has an improved output power of 620 W and an increased module efficiency of 23.0%. Designed for power plants, the module has dimensions of 2382 x 1134 x 30 mm.

Like its predecessor, the upgraded version of Hi-MO 7 module benefits from LONGi’s multi-dimensional product design and strict raw material selection as well as its advanced manufacturing processes. Hi-MO 7 uses high-quality monocrystalline silicon wafers, optimized module encapsulation and cell paste, high-precision SMBB connections and intelligent automatic junction box welding technology. The use of digitized manufacturing and quality control platforms with integrated AI detection technology further guarantees the quality of Hi-MO 7. As a result, Hi-MO 7 guarantees a performance degradation of less than 1% in the first year and a linear performance degradation of less than 0.4% from the second to the 30th year.

The new module uses the same advanced frame design and features a 30mm thick high-strength aluminum alloy frame for improved durability and load-bearing capacity. Its robust construction allows it to withstand high snow loads and high wind pressure to ensure reliable performance and durability in extreme weather conditions. The module’s 80% bifaciality and excellent performance temperature coefficient of -0.28%/°C mean higher energy yields, which is especially important in colder climates and snowy regions such as Canada.
