JinkoSolar and TÜV Rheinland to create testing standards for bifacial modules


Chinese tier-1 solar company JinkoSolar is to team up with Germany’s TÜV Rheinland to develop a standardized testing method for bifacial solar modules.

An independent provider of technical services for testing, inspection and certification, TÜV Rheinland is a respected name throughout the solar industry and will work collaboratively and closely with JinkoSolar to create new bifacial benchmarks.

A solar cell working group – the IEC/TC82 – was convened by JinkoSolar to invite both domestic (Chinese) and international experts to discuss how the new standard – ICE60904-1-2 for bifacial technology should shape up.

According to JinkoSolar, participation at the IEC meetings – as well as PVQAT (the International Photovoltaic Quality Assurance Task Force) gatherings – allowed the Chinese firm to develop and establish industry standards that would be used for the testing of future bifacial module iterations.

A working group created by TÜV Rheinland’s Dr. Christos has welcomed JinkoSolar’s input, and resulted in the creation of a draft and testing method. JinkoSolar says it is one of the first companies to receive a final testing report based on this draft.

“As an industry leader, JinkoSolar has deployed considerable resources towards further developing its bifacial technology and standardizing testing methods,” said company VP Hao Jin. “We will continue to work with authoritative independent technical service providers such as TUV Rheinland to further study and standardize testing methods for bifacial modules used in outdoor power generation systems.”

In May JinkoSolar announced that it was to embark on a research collaboration with the Solar Energy Research Institute of Singapore (SERIS) to develop high-efficiency bifacial solar cells. This partnership is expected to expedite the mass commercialization of bifacial PV modules, beginning in earnest at the start of 2018, Hao Jin said.
