What is BS EN IEC 60904 ‑ 10 about?
BS EN IEC 60904 ‑ 10 is a part of multi-series standard IEC 60904 that describes the procedures to measure the dependence of any electrical parameter (Y) of a photovoltaic (PV) device with respect to a test parameter (X). It determines the degree at which this dependence is close to an ideal linear (straight-line) function.
BS EN IEC 60904 ‑ 10 also gives guidance on how to consider deviations from the ideal linear dependence and in general on how to deal with non-linearities of PV device electrical parameters.
BS EN IEC 60904 ‑ 10 gives the procedures to determine the deviation of the Y ( X ) dependence from the linear (straight-line) function are described in Clause 6 (measurements under natural sunlight and with solar simulator), Clause 7 (differential spectral responsivity measurement...
