Independent research and development in our country the direct-injection long pulse solar simulator has reached the international leading level

Recently, the first domestic & other; Efficient photovoltaic modules photoelectric parameters measurement & throughout; Ability to verify project ( NIM2017PV01） The results of statistical analysis. The project is by the China institute of metrology ( Conformity assessment of China national accreditation council ( CNAS） Ability to verify the provider CNAS PT0037) And the China quality certification center ( CQC) Organization.

the ability verification purpose aimed at by conducting & other; Efficient photovoltaic modules photoelectric parameters measurement & throughout; Ability validation project, which can be related to laboratory photovoltaic measuring and testing field at home, in the standard test under the condition of measuring the parameters of the photovoltaic modules key photoelectric performance comparison and verification technology ability, including: short circuit current and open circuit voltage and maximum power. Is also a validation of the various laboratory tests ability, help in the field of photovoltaic (pv) measurement and detection ability, promote academic exchange and the discussion between the laboratory and eventually to the unity of the pv value in our country.

the ability verification project of 51 laboratory covers the main third-party laboratory testing machine structure, photovoltaic enterprises, equipment production enterprise, the third party testing institutions 27, photovoltaic enterprises on 21, 3 equipment production enterprises, project lasted more than a year. Laboratory quality management system in accordance with ISO/IEC 17025 standards, and adopted by CNAS organization of expert evaluation or are preparing to take relevant measurement capability evaluation. For the performance of photovoltaic modules photoelectric measuring ability have been obtained or is applying for qualification for CNAS recognized legal effective measure.

the testing results show that the shaanxi's laboratory ( No. 1008) With long its home-grown direct-injection pulse solar simulator ( 投入, 20) Took part in the ability to verify, and many have abroad test equipment unit PK, accuracy of test results among the leading ( The following figure, the Z value on behalf of the test results and the standard deviation, the smaller deviation absolute value represents the more accurate test results) 。
