IEC 60904-10:2009 describes procedures used to determine the degree of linearity of any photovoltaic device parameter with respect to a test parameter. It is primarily intended for use by calibration laboratories, module manufacturers and system designers. The main technical changes with regard to the previous edition are as follows:
- added clause for two-lamp method for I_sc linearity;
- removed clause on spectral responsivity nonlinearity because it is not used by any PV testing / calibration group.
