In March 2015, CTC (China Building Materials Certification & Inspection Group Co., Ltd.) Foundry Ministry conducted a spot check on the PV modules and conducted quality inspection work of 31 companies those entered the list of "Regulatory Conditions for PV Manufacturing Industry" in 2014 and 2015 respectively. To ensure the randomness of sampling, enterprises are not informed in advance before sampling. All the modules are sent directly from production line to Hainan demonstration base to form string-connected string inverters for on-grid power generation, and then the power attenuation detection before and after natural aging is carried out.
Recently, Haitai won the certificate of PV module "leader" power attenuation by the CTC (China Building Materials Inspection and Certification Group Co., Ltd.)
From April 2015 to April 2016, in photovoltaic products spot check carried out by the Ministry of Industry, the test result of Haitai’s PV modules that power attenuation in the first year turned out to be 1.38% after through one year’s actual power attenuation tracking at Hainan Photovoltaic Test Base, which complies with PV modules ‘Leader’ power attenuation standard.
Based on this, from May 2016 to May 2017, Haitai asked CTC (China Building Materials Certification & Inspection Group Co., Ltd.) to track actual power attenuation for PV modules again and finally won good results of average power attenuation rate is 0.40% in the second year, and ranked top in 31 photovoltaic companies those were sampled.
