GB/T 6495.10-2025 Active

This document specifies the procedure for measuring the correlation between any electrical parameters (Y) of photovoltaic devices and test parameters (X), and determining the degree to which this correlation approaches an ideal linear (straight-line) function. It provides guidance on how to account for deviations from the ideal linear correlation and how to handle the non-linear characteristics of the electrical parameters of photovoltaic devices. The measurement methods described in this document are applicable to all photovoltaic devices, but caution is required when using multi-junction photovoltaic devices. The measurements should be conducted on the device itself or, in some cases, on equivalent devices with the same technology, and the device must be stable according to the standards set out in the relevant provisions of IEC 61215. These measurements should be carried out prior to all measurement and correction procedures that require linear devices or impose restrictions on devices with specified non-linear characteristics.
