Photovoltaic devices - Part 2: Requirements for photovoltaic reference devices

IEC 60904-2:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. EC 60904-2:2015 gives requirements for the classification, selection, packaging, marking, calibration and care of photovoltaic reference devices. This standard covers photovoltaic reference devices used to determine the electrical performance of photovoltaic cells, modules and arrays under natural and simulated sunlight. The main technical changes with regard to the previous edition are as follows: - addition of a test procedure in simulated sunlight of subsequent measurement of primary and secondary reference device; - definition of standard test conditions; - reduction of allowed diffuse component for secondary reference cell calibration.
