LONGi has expanded its Hi-MO solar module series with the introduction of Hi-MO X10 panels
Aimed at the distributed generation segment, these offer a power output of up to 670 W and efficiency of 24.8%
The company targets an annual output of between 20 GW and 30 GW for next year
One of the world’s largest solar PV manufacturers, LONGi Green Energy Technology has launched a new module claiming up to 24.8% module efficiency in mass production which, it says, breaks the global module mass production efficiency record.
A new entrant to the manufacturer’s Hi-MO series, Hi-MO X10 is based on LONGi’s proprietary Hybrid Passivated Back Contact (HPBC) 2.0 cell technology, which exceeds 26.6% cell efficiency in mass production, claims the Chinese company.
The maximum mass production power output of the module reaches 670 W, that LONGi says it is more than 30 W higher than the industry’s TOPCon mainstream module power. It uses the current popular module size of 2,382 mm x 1,134 mm.
LONGi has introduced the Hi-MO X10 modules in 4 versions initially, all for the distributed generation segment. These are 54-cell extreme black, 72-cell single glass, 72-cell anti-dust, and 72-cell double glass.
Some of the salient technical features of the Hi-MO X10 module are:
It uses high-quality n-type TaiRay silicon wafers with their advantages of high resistance concentration, good impurity gettering effect and stronger mechanical properties. Produced using CZ method, these monocrystalline wafers have a thickness of 130±8μm, oxygen content of ≤6E+17 at/cm³ and carbon content of ≤5E+16 at/cm³.
A zero busbar (0BB) structure lends the modules no grid line on the front, which is said to let the light directly penetrate the connecting welding strip, leading to reduced current transmission distance and increasing the module power by 5W+.
A ‘unique’ bypass diode structure used can bypass the blocked area autonomously, thus helping reduce the power loss by more than 70% compared with TOPCon products. Hot spot concerns are also taken care of as LONGi stressed that the module technology reduces overheating by more than 28% compared to standard products.
The power temperature coefficient is -0.26%/°C, which is 0.03%/°C optimized compared to TOPCon; it decays by 1% in the first year and linearly decays by 0.35% for the remaining 29 years
The manufacturer is providing a 15-year product process warranty, and a 30-year product power warranty
LONGi plans to launch the X10 product on a large scale in Q4 2024 for supply in batches, but mass production at GW-scale is planned in Q1 2025. In 2025, it forecasts an output range of 20 GW to 30 GW.
LONGi will be present at the upcoming TaiyangNews Reliable PV Module Design 2024 Conference, to be held virtually on October 21 and 22, 2024, where the discussion will revolve around technologies and processes that help build long-lasting solar modules.
