The Bifaciality of LONGi Solar's Bifacial PERC Cell Brakes World Record
BEIJING, Dec. 7, 2017 /PRNewswire-AsiaNet/ --

The National Center of Supervision and Inspection on Solar Photovoltaic 
Products Quality (CPVT) issued an independent test report showing that LONGi 
Solar's bifacial PERC monocrystalline cells achieved a world record bifaciality 
of 82.15%. 

LONGi Solar released its bifacial PERC monocrystalline module (Hi-MO2) at 
Shanghai SNEC 2017. The goal is to supply modules to meet the growing market 
demand for higher efficiency products and to the China Top-Runner Programs.

LONGi's Hi-MO2 features high power technology, high-energy yield and low LCOE. 
For LONGi Solar, Hi-MO2 is synonymous with high efficiency, bifacial power 
generation, and provides the launch point for the new era of highly efficient, 
bifacial PERC monocrystalline power generation technology. 

Hi-MO2 captures the best features of LONGi's Hi-MO1 technology platform - 
low-degradation, high-power PERC technology - and combines them with the 
bifacial technology. In mass production, the efficiency of the front side 
exceeds 21.2%. Light reception of the backside can bring significantly 
additional energy yield. If the backside power yield increases the overall 
module efficiency by 10%, the power of bifacial PERC module can reach 330 watts 
for 60-cell module (300 watts from the front side), and 396 watts for 72-cell 
module (360 watts from the front side). 

The bifacial PERC modules come with double glass lamination. Combined with low 
degradation mono PERC technology, Hi-MO2 offers first-year degradation below 
2%, and the average annual degradation below 0.45% for 30 years - significantly 
better than conventional modules. Meanwhile, the adoption of a double-glass 
improves PID resistance and can extend the module life beyond 30 years. 

"Hi-MO2 extends the advantages of monocrystalline PERC to the back side of the 
module, without increasing costs. Combined with higher power and higher energy 
yield, Hi-MO2 reduces LCOE and brings more benefits to the PV power plant 
investors," Li Wenxue, President of LONGi Solar said.

The successful launch of bifacial monocrystalline modules is a testament to the 
PV market's desire for high-efficiency, high-reliability and high-yield 
products, and a full recognition of LONGi Solar's constant innovation in 
monocrystalline PERC cell technology. 

The bifaciality of bifacial PERC cells in the market is about 75%, and LONGi 
Solar's monocrystalline bifacial PERC cell has increased the bifaciality to an 
industry-leading 82.15%, which has not only enriched the application scenarios 
of PERC bifacial cells, but also improved cost performance in addition to 
higher energy yield.
