Solar Energy

In the solar industry, China General Certification Center (CGC) is one of the first third-party organizations in China to certify and test solar photovoltaic (PV) products. It is an accredited certification body (RECB) and inspection body (REIB) of the IEC System for Certification to Standards Relating to Equipment for Use in Renewable Energy (IECRE). It is also an accredited National Certification Body (NCB) and CB Testing Laboratory (CBTL) of the IEC System for Conformity Assessment Schemes for Electrotechnical Equipment and Components (IECEE). This allows CGC to provide a turnkey CB certification testing service for PV customers in China and globally.

CGC is the designated project review agency for China's Golden Sun Demonstration Project. Its customers include the top ten manufacturers in terms of shipment volume. CGC has issued over 3,600 PV product certificates and has served more than 60 GW of solar power plants. The industry widely recognizes CGC’s technical capabilities and service quality. Its testing and certification results have been accepted by government agencies, developers, financial institutions, and other parties.

CGC is the supporting institution of China’s “National Energy Key Laboratory for Wind and Solar Simulation, Testing and Certification”. It has established a 5,000㎡ East China PV Testing Center in Jiaxing, Zhejiang, which is accredited by CNAS and CMA. The center is a CBTL testing body recognized by IECEE. CGC has also established large-scale field test bases in Heilongjiang, Inner Mongolia, Hebei, Zhejiang, Hainan, and other locations. This makes CGC the first authoritative third-party organization in China with field test capabilities in multiple temperature zones, including cold temperate, temperate, subtropical, and tropical zones.
