Established in Berlin, Germany in October 2013 as a certification body of unified global standard, the Global Solar Certification Network (GSCN) is headed by the Chairman and Secretary General of the European Solar Keymark Certification. The GSCN members include many world-famous solar thermal utilization testing, certification and standard compilation agencies, such as ITW, SRCC and ISO TC180. As agreed by IEA SHC China National Representative with a signed National Participation Letter, the National Center for Quality Supervision and Inspection of Solar Water Heater (Beijing), China Academy of Building Research Certification Center and Tus-Clean Energy Group were selected as the first batch of accredited laboratories, certification centers and production enterprise representatives in GSCN Asia in March 2014.

From March 12, 2014 to March 13, 2014, GSCN held its first meeting in Gran Canaria, Spain. During the meeting, the attendees discussed GSCN"s logo, organizational structure, etc., set up a board of directors, and elected the chairman, vice chairman, financial director, secretary, etc. The following Chinese people were appointed as the directors of GSCN Executive Board: He Tao, Director of the National Center for Quality Supervision and Inspection of Solar Water Heater (Beijing) and Member of Science and Technology Committee under Tsinghua Solar Research Institute, and Zhou Xiaowen, Tus-Clean Energy Group. The executive board is composed of 36 directors from six continents (Asia, Europe, North America, South America, Africa and Oceania), 6 directors per continent, including two from certification bodies, 2 from testing organizations and 2 from companies.

At present, the GSCN members are distributed in the five continents: Europe, Asia, North America, Africa, Oceania. The working team of GSCN aims to establish a unified and border-free certification system and logo by taking the world's top solar thermal utilizing testing laboratories and certification centers as platforms. Any certified testing laboratory / certification center thereunder will be mutually accepted and recognized in the GSCN network worldwide, which means that any report issued by any member shall have the same effect as the report issued by any other GSCN member in its country or region. Such a new certification system will completely break the technical barriers against import & export of products and create a barrier-free trade environment for solar thermal production enterprises worldwide. In addition, as a new opportunity and new challenge for the Chinese testing organizations, it is capable of further promoting sound development of China's testing and certification institutions, and expanding the influence of China's testing organizations in the international market.
