LONGi wins RETC "High Achievers" award for outstanding module performance
XI'AN, China, Jan. 13, 2021 /PRNewswire-AsiaNet/ --

The US Renewable Energy Testing Center (RETC) has released its "Photovoltaic 
Module Index Report" (PVMI) for 2020. Having won a "High Achievers" award in 
2019, LONGi has once again carried off the award for outstanding performance 
following comprehensive evaluation of global photovoltaic modules by RETC. 

LONGi's performance in three indicators of reliability, performance and quality 
identified it as one of only three companies to achieve the award. The company 
also became the only module manufacturer to perform well in all 8 individual 
tests, underlining the high reliability and excellent performance of its 
monocrystalline modules.

The PVMI provides a high-level overview of relevant tests carried out by RETC 
within reliability, performance and quality indicators, followed by a sampling 
of test data to recognize high performers and showcase high achievement in 

Being awarded as overall "High Achiever" and demonstrating solid top 
performance on all 8 indicators are good testament to LONGi's consistent 
philosophy of delivering reliable products to customers. As the world's leading 
solar technology company, LONGi focuses on product reliability, from design to 
production, providing customers with reliable and value-added photovoltaic 
modules. Module design starts with theoretical simulation using relevant 
optical, electrical and mechanical models. Module power, efficiency, energy 
yield and reliability will all be considered before design is finalized; For 
module BOM selection, the company has always maintained a highly cautious 
approach, ensuring long-term product reliability. In addition, LONGi uses Ga 
doping to control mono PERC module LID, and has also optimized the hydrogen 
passivation process to mitigate LeTID. 

Meanwhile, to ensure module reliability, LONGi goes beyond standard testing 
requirements, establishing a variety of differentiated testing methods based on 
the results of well-known research institutions and third-party experts. As for 
the production process, highly automated equipment not only improves 
efficiency, but also helps ensure production stability. A comprehensive quality 
control system guarantees product excellence.
