LONGi’s high-wattage Hi-MO 5 series module: now rolling off production lines

LONGi solar

LONGi Solar says it has achieved volume production of its Hi-MO 5 series module at its module factory in Xianyang City, Shannxi Province, China. Originally announced in June 2020, the first Hi-MO 5 rolled off the production line on Sept. 8.

This new generation product is LONGi’s effort to get into the super-high-wattage-PV-panel frontier, with a front-side power up to 540W.  Based on M10 (182 mm) standard gallium doped monocrystalline wafers, this high performance product has a conversion efficiency over 21% to bring optimal LCOE to ultra large-scale PV projects.

Hi-Mo backstory and specs

Hi-MO 5 adopts a “Smart Soldering” technology for high reliability of micro gap interconnection, product efficiency and stable current output. This proprietary technology uses integrated segmented ribbons that maximize light capture and reliably connect cells with reduced gap distance.

The combination of these technological innovations can increase the module efficiency of Hi-MO 5 by 0.3% (compared with conventional multi-busbar products) and reduce the tensile stress on the cell by 20%, thus improving the product quality.
Compatibility and reliability create ultra-high value for global customer

The working current of LONGi Hi-MO 5 module is about 13A. Including bifacial gain, the operating current remains within the maximum input current range of inverters, with no power generation losses.

The module size of Hi-MO 5 is 2256 x 1133 mm, and its length is perfectly compatible with 1P and 2P horizontal single axis tracking systems. Hi-MO 5 adopts “double glass with frame” construction that provides high load capacity (front and back static load of 5400Pa, 2400Pa respectively) and proven long-term reliability without need for the addition of a rear crossbeam.

Production ramp up

To ramp-up Hi-MO 5 mass production, LONGi is now accelerating the construction of new production capacity. It is expected that the production capacity of LONGi Hi-MO 5 will reach 12GW this year.

LONGi Solar’s Module Factory in Xianyang City, Shaanxi was already running at full capacity in May with annual production capacity reaching 5GW. In addition, LONGi Solar’s Module Factory in Jiaxing City, Zhejiang is under construction and will also bring another 5GW annual production capacity. LONGi will continue expand its global layout and continue to invest in production capacity to meet the needs of future solar market.
