On April 19, SNEC PV Power Expo 2017 kicked off in Shanghai. President Li Zhenguo of LONGi Group and President Li Wenxue of LONGi Solar unveiled a heavyweight new solar module - Hi-MO2 to the audience. The product boasts high power, high energy yield and low LCOE, and will start a new era of high efficiency monocrystalline PERC bifacial power generation technology.
Hi-MO2 is a bifacial power generation product developed based on monocrystalline bifacial PERC technology; the power of the 72-cell module reaches 360-365W, while the power of the 60-cell module reaches 300-305W. The front side is equivalent to conventional PERC with cell efficiency exceeding 21%. Meanwhile, the back side adopts a glass package, achieving bifacial light reception and power generation. Backside efficiency is no less than 75% that of the front side. The backside can increase energy yield up to 25% (varying with the design and background condition of the PV system), and can bring higher returns to the investors.
Last year, LONGi Solar launched Hi-MO1 based on advanced PERC cell technology and mono-Si low LID solution. The Hi-MO2 developed on the basis of Hi-MO1's low LID technology and bifacial PERC technology can achieve first-year degradation less than 2%, and average annual degradation less than 0.45%, both superior to conventional modules.
"Hi-MO2 extends the strengths of mono PERC to the backside of the module, and can achieve higher power and higher energy yield without increasing costs, which will help decrease the LCOE, and bring more value for PV power plant investors," said Li Wenxue, President of LONGi Solar. "Improving efficiency and providing low-price high-quality products has always been the technology innovation ideal upheld by LONGi. LONGi has the confidence to continuously provide high efficiency monocrystalline PV products with the best cost performance ratio for global customers, to use technology to speed up progress towards grid parity, and to make more contributions to improving environment condition."
LONGi Solar's 365W Hi-MO2 module has reached mass production. In the future, Hi-MO2 will be widely used in large scale utility power plant, commercial rooftop, fishery-PV integrated floating power plant and other distributed PV projects.
