LONGi Certified by China Quality Certification Center (CQC) as a Witnessed Manufacturer's Testing (WMT) Laboratory

CHANGCHUN, China, January. 21, 2020 /PVTIME/ -- China Quality Certification
Center (CQC), one of the world’s leading third-party testing and certification
institution has accorded LONGi the Witnessed Manufacturer's Testing (WMT)
certification for the international standards of IEC 61215 and IEC 61730. The
certification is strong validation of the product quality control and
laboratory testing capabilities in LONGi.

CQC provides assessments and certifications to photovoltaic manufacturers
through cooperation with laboratories. With the CQC WMT certification, LONGi
can now implement photovoltaic module certification tests based on the
international standards of IEC 61215 and IEC 61730 in its own laboratory. Tests
will be executed by LONGi Test Engineers and independently witnessed by CQC
Project Engineers. LONGi laboratory will issue the test reports, which will be
jointly signed by LONGi and CQC. The use of manufacturer’s laboratory testing
facilities with independent eyewitness verification will reduce project cycle
time in sample delivery, improve the efficiency of photovoltaic product certification,
and increase the competitiveness of the product.

"LONGi and CQC are long-term strategic partners, and the WMT (Witnessed Manufacturer's Testing) certification is validation of the high management level and testing ability of LONGi's laboratory. This is also validation of the laboratory's compliance with IEC International Standards and CQC Recognition Rules. We look forward to working with LONGi to derive their advantages in technological innovations in the photovoltaic field, consolidate the quality foundation work such as standards, testing, certifications, and promote the high-quality development of the photovoltaic industry in China." Ms. Xing Heping, CQC Marketing Director and Head of New Energy Department said at the ceremony.

Dr. Lv Jun, Vice President of LONGi Solar, said, "LONGi R&D
laboratory successful receipt of CQC WMT certification is strong recognition of
LONGi's comprehensive facilities and R&D capabilities. During the entire
evaluation process, the professional technical team of CQC provided valuable
support to LONGi. In addition to certification testing, LONGi facilities
laboratories have pivotal roles in product quality control and the introduction
of new materials. The acquisition of CQC WMT certification proved that LONGi has
strong product quality control capabilities for our customers. "

Malaysia, Quzhou, Zhejiang Province and Taizhou, Jiangsu Province have
successively obtained "Laboratory Qualification" from authoritative
third-parties. LONGi will enhance its R&D capabilities and bring more
high-quality photovoltaic products to the market quickly, to promote the
