Hi-MO3 with 320W Front-side Power: A Worthy Successor of Bifacial PERC

Global News

——May 28th, 2018. LONGi Solar, a leading, vertically integrated monocrystalline manufacturer, showcased its third-generation product - the Hi-MO3 half-cut bifacial PERC module - at the SNEC (2018) International Photovoltaic Power Generation and Smart Energy Exhibition & Conference at the Shanghai New International Expo Center. LONGi Solar’s Hi-MO series have led the industry in technology development of monocrystalline PERC with high power, high yield and low LID. Hi-MO3 combines advanced monocrystalline PERC cell technology and bifacial, half-cut module construction to provide energy producers with a brand new choice to reduce LCOE.

——May 2016. LONGi Solar released the first-generation Hi-MO1 products enabled with high-efficiency, low-LID PERC technology, setting off rapid growth in monocrystalline PERC. Empirical data showed that Hi-MO1 energy yield per watt was 3% higher than that of conventional modules;

——April 2017. The 2nd generation Hi-MO2 bifacial PERC was released. Based on continuously developed PERC technologies, the front-side power of Hi-MO2 (60-cell) module exceeded 300W, with rear-side yield of 5-25% and a 30-year quality assurance that helps the industry significantly reduce LCOE and enhance project profitability;

——May 2018. Based on Hi-MO2 integrated with advanced half-cut module construction and LONGi Solar’s continuous breakthroughs in monocrystalline PERC technology, the 3rd generation Hi-MO3 half-cut bifacial PERC module pushed front-side power up to 320W. 

Hi-MO3 inherits its predecessor’s low-LID and high rear-side yield, with more advantages:

1. Higher power. The power on the front-side reaches 320W (60-cell) / 380W (72-cell) in series production;

2. Lower hot spot effect. Under the same test conditions, the average hot spot temperature of half-cut module is 10-12 ℃ lower than that of full-sized cell modules;

3. Higher yield. The yield under shaded conditions is significantly enhanced.

4. Lower LCOE, with reductions of up to 11%.

In terms of power generation, Hi-MO3 with half-cut cells and bifacial construction has the efficient power of monocrystalline PERC, better performance in shade, enhanced energy yield, lower hot spot temperature and lower LCOE. In the high-irradiation regions and under shaded conditions, Hi-MO3 advantages help to sharply reduce LCOE and accelerate the progress of PV grid parity.
