BAODING, China, June 22, 2017 /PRNewswire/ -- PV bifacial
technology rises gradually in recent years, and it quickly becomes
the highest technology of mass production in the PV industry. Along
with the bifacial power generation market gradually enlarging,
industry constraints are also being emphasized.
International test standards in the PV industry are
basically about traditional mono-facial power generation PV
devices, which are not applicable to evaluate the performance and
unable to test the electrical parameters accurately of bifacial PV
devices. The fact that there is no international
standard for bifacial power generation leads to two disadvantages.
Firstly, the nominal module output impact directly on the interests
of both buyers and sellers, so they have lots of
disagreements on how to indicate that figure. Secondly, ultimate
nominal output of bifacial module will impact directly on the
design of PV power plant.
Dr. Chirstos, who comes from TUV
Rheinland which is an internationally recognized third-party
certification body, leads the way of organizing the
writing of the bifacial module test method earlier this year. The
discussion group was formally established, and the
official publishing of this test method will hopefully solve the
complicated problem.
Yingli Solar, the leader in N-type bifacial
technology, participated actively in the draft discussions and
verification tests, and finally became one of the first companies
who have finished the test draft. Recently, Yingli N-type PANDA
BIFACIAL module became the first officially defined product for the
TUV Rheinland bifacial module test
method draft, and got the final test report.
Yingli Solar has a powerful voice in the field of
bifacial power generation technology with 8 years' experience. In
2016, Yingli Solar, cooperated with
China General Certification (CGC) center, prepared jointly the
standard of PV Industry Association "Electrical Performance Testing
Method for Bifacial Module". At the end of 2016, Yingli Solar received the bifacial module
certification from CGC, and became the first and currently the only
company which get this certification.
Yingli Solar has been engaged in research on N-type
bifacial technology for years. From 2016, the N-type bifacial
module named PANDA BIFACIAL SERIES has been launched and became the
principal product of the company. Mr. Vincent Yu, Vice president of Yingli Green
Energy Holding Co., Ltd., said that Yingli's PANDA
BIFACIAL modules is far beyond IEC standards for PID, high humidity
and salt-mist test. The quality of PANDA BIFACIAL modules is
completely guaranteed.
Meanwhile, Yingli's PANDA BIFACIAL modules could generate more
energy. On May 23rd, 2017, Yingli's
50MW N-type bifacial power plant, one of "Top Runner
Projects" which has been officially approved by the State, had been
successfully inspected. According to the actual
generating data, the cumulative output is 60.88 million kWh in 10
months after connected to the grid. For each month, the energy
yield of PANDA BIFACIAL power plant is 10.4 - 15.6% higher than the
regular multi-crystal power plant. From the beginning of 2017,
Yingli Solar has established
official power plant database, energy yields of PANDA BIFACIAL
modules in distributed PV systems are about 20% more every month,
and the highest yield gain is greater than 30%. So
PANDA BIFACIAL modules could be called as the national
treasure in the PV industry.
The draft of international test standard for
bifacial power generation is expected, and it will be sure that
PANDA BIFACIAL modules have not just been on the domestic stage. In
future, Yingli will carry out wider and deeper cooperation
with TUV Rheinland, which
makes Yingli "PANDA BIFACIAL" create infinity possible.
