BS EN IEC 60904-1:2020 PDF

What is BS EN IEC 60904 ‑ 1 about?

BS EN IEC 60904 - 1 describes procedures for the measurement of current-voltage characteristics (I-V curves) of photovoltaic (PV) devices in natural or simulated sunlight. These procedures are applicable to a single PV solar cell, a sub-assembly of PV solar cells, or a PV module. They are applicable to single-junction mono-facial PV devices. Additionally, BS EN IEC 60904 ‑ 1 provides informative annexes are given, concerning area measurement of PV devices (Annex A), PV devices with capacitance (Annex B), measurement of dark current-voltage characteristics (dark I-V curves) (Annex C) and effects of spatial non-uniformity of irradiance. Note 1: BS EN IEC 60904 ‑ 1 is applicable to non-concentrating PV devices for use in terrestrial environments, with reference to the global reference spectral irradiance defined in IEC 60904-3 . Note 2: BS EN IEC 60904 ‑ 1 may also be applicable to PV devices for use under concentrated irradiation if the application uses direct sunlight and reference is instead made to the direct reference spectral irradiance.  ...
