LONGi designed the new the Hi-MO 5m 54c module mainly for residential and C&I rooftop systems. With just 54 cells, this new Hi-MO 5m module is produces a maximum power output of 415W, and achieves an efficiency of 21.25%. This is not yet available in the U.S., but should be coming later in the year.

This new addition expands LONGi’s Hi-MO 5 product line, which is hugely popular in large-scale installations. By the end of 2021, Hi-MO 5 modules with 72 cells (144 half-cut cells) had been supplied to some 600 clients in 57 countries, with cumulative shipments exceeding 10 GW.

Panel design: Hi-MO 5 products use M10 (182mm) industry standard solar cells. Boundary conditions for design and application of PV modules must account for varying conditions across different links of the supply and value chain. LONGi beliece these 182mm half-cut cells are optimal for all manufacturing processes, from ingots and wafers to cells and modules as well as for module deployment processes, transportation, installation, and overall system integration.

Cells: Hi-MO 5m 54-cell modules feature PERC Gallium-doped p-type half-cut cells with the highest resistance against light aging (lowest LID) for maximum energy yield and are backed with a 25-year performance warranty. This technology has won performance and technology awards from the Renewable Energy Testing Center (RETC) and PV Evolution Labs (PVEL).

Here is an in-depth look at the panel’s resistance to snow loads.

Performance: The Hi-MO 5m performs well in low-light conditions (such as morning and evening) and even unfavorable lighting angles due to its temperature coefficients. LONGi also notes its integrated segmented ribbon technology traps more light into the solar cell, simultaneously reducing cell stress.

Installation: With a module size of 1722mm by 1134mm, the Hi-MO 5m 54-cell module should be easier to handle. The Hi-MO 5m 54-cell series supports most standard mounting systems clamping on the long and short sides of the module frame, as well as lay-in or slide-in systems and elevation systems with module edge clamping. The modules are also compatible with most popular inverters. Their short circuit current is low and well below 15 Amps. At less than 2m² in size and less than 23kg in weight, the module small and light enough for one person to install.
