Foreword
The text of document 82/582/FDIS, future edition 2 of IEC 60904-10, prepared by IEC TC 82, Solar
photovoltaic energy systems, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60904-10 on 2010-03-01.
This European Standard supersedes EN 60904-10:1998.
The main technical changes with regard to the EN 60904-10:1998 are as follows:
– Added clause for two-lamp method for Isc linearity.
– Changed standard deviation as a metric for linearity to percent deviation from linearity. This was done
because a non-linear device can have a low standard deviation and percent deviation is the
quantitative number that matters for the parameter of interest.
– Removed clause on spectral responsivity nonlinearity because it is not used by any PV
testing / calibration group. For testing real PV devices it is difficult to make this error significant in the
spectral mismatch correction factor while still passing Isc linearity. Measuring the responsivity over the
entire response range means that the device will probably fail the temperature linearity near the band
edge.
– Added a clause to allow short circuit linearity with temperature or total irradiance to be determined
from absolute spectral responsivity measurements. This data is routinely reported in PTB primary
reference cell calibration certificates.
– Added report clause in compliance with ISO/IEC 17025 requirements.
– Often the temperature coefficient of short circuit current is very small so measurement errors can
result in percent deviations outside the accepted range. Therefore, the following text was added to
7.3c): “If the temperature coefficient of short circuit current is less than 0,1 %/K, then the device can
be considered linear with respect to this parameter.”
