Photovoltaic devices

Part 10: Methods of linear dependence and linearity measurements

(IEC 60904-10:2020); German version EN IEC 60904-10:2020
Class/Status: Standard, valid
Released: 2022-10
VDE Art. No.: 0100691

This part of IEC 60904 describes the procedures used to measure the dependence of any electrical parameter (Y) of a photovoltaic (PV) device with respect to a test parameter (X) and to determine the degree at which this dependence is close to a perfect linear function. It 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.
