IEC 60904-1:2020 describes procedures for the measurement of current-voltage characteristics (I-V curves) of photovoltaic (PV) devices in natural or simulated sunlight. These procedures are applicable to a single PV solar cell, a sub-assembly of PV solar cells, or a PV module. This document is applicable to non-concentrating PV devices for use in terrestrial environments, with reference to (usually but not exclusively) the global reference spectral irradiance AM1.5 defined in IEC 60904-3.

IEC 60904-10:2020 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 an ideal linear (straight-line) 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. This third edition cancels and replaces the sec...view more

Photovoltaic (PV) modules are electrical devices normally intended for continuous outdoor
exposure during their lifetime. Highly corrosive wet atmospheres, such as marine
environments or locations near the ocean or other large bodies of salt water, could eventually
degrade some of the PV module components (corrosion of metallic parts, deterioration of the
properties of some non-metallic materials – such as protective coatings and plastics – by
assimilation of salts, etc.) causing permanent ...

This document provides a method for determining how well a framed PV module performs
mechanically under the influence of inclined non-uniform snow loads. This document is
applicable for framed modules with frames protruding beyond the front glass surface on the
lower edge after intended installation and as such creates an additional barrier to snow sliding
down from modules. For modules with other frame constructions, such as backrails formed in
frames, on the side edges, on the top edge an...
