On May 28, at SNEC 2018, LONGi Solar released
its Hi-MO3, an innovativehalf-cut bifacial p-mono PERC module. This is another
advanced PERC cell and module construction by LONGi Solar which follows on the
heel of its Hi-MO1 PERC low-LID module in 2016 and Hi-MO2 bifacial PERC module
in 2017.
Hi-MO3 uses half-cut techniques to reduce
the operating current of the cell by half, effectively reducing resistance losses
and increasing power by 5-10 watts on average. With bifacial technology, the front-side
power of the module reaches 320W (60-cell), and the bifaciality is
higher than 75%. Under shaded conditions, Hi-MO3 yields more energy than a full-cell
module array. The advantages of Hi-MO3 include lower hot
spot temperature that reduces LCOE by a factor of 10% or more compared to
conventional products at all irradiation levels.
“This 3rd generation of Hi-MO
with higher power, higher yield, lower hot spot effect further improves product
efficiency and performance which in turn accelerates the reduction of LCOE,” Zhong
Baoshen, Chairman of LONGi Solar, said. “It’s the result of the R&D team’s
relentless focus in technological innovations. We expect that the launch of
Hi-MO3 can bring new breakthroughs to the development of the industry.”
“PV power generation as a strategic
emerging industry in China has huge development potential for the future. PV
companies must have a sense of responsibility and mission to continuously make
innovations and progress,” said Li Junfeng, former director of National
Center for Climate Change Strategy and International Cooperation. Shi Dinghuan, Former Counselor of the State Council and
honorary chairman of China Renewable Energy Society, added, “the
advancement of energy revolution and green revolution requires the promotion of
technical innovation in PV products, continuous improvement of photoelectric
conversion efficiency and PV investment value, and further acceleration of grid
parity. LONGi Solar’s practice in technological innovation and product innovation
deserves encouragement and recommendation.”
LONGi Solar has continuously increased R&D
investment in the science and technology of mono-crystalline. In the past five
years, the company invested a total of RMB 2.464 billion. In 2017 alone, the
company invested RMB1.108 billion, 6.77% of its sales, into R&D, the
highest among PV companies in the world. With continuous R&D investment,
LONGi Solar has made remarkable technological progress. Since September 2017, the
company has broken the world records for PERC cell and module technology eight
times.
In 2017, LONGi Solar shipped 4.66GW
monocrystalline modules, ranking first in the world in monocrystalline cell and
module shipments for three consecutive years. The release of Hi-MO3 is expected
to further accelerate the progress of PV grid parity.
