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 60904-9:2020 is applicable for solar simulators used in PV test and calibration laboratories and in manufacturing lines of solar cells and PV modules. This document define classifications of solar simulators for use in indoor measurements of terrestrial photovoltaic devices. Solar simulators are classified as A+, A, B or C based on criteria of spectral distribution match, irradiance non-uniformity in the test plane and temporal instability of irradiance. This document provides the required m...view more

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

IEC TR 60904-14:2020 provides guidelines for measurements of the maximum power (Pmax) output of single-junction photovoltaic (PV) modules and for reporting at standard test conditions (STC) in industrial production line settings. As it is desirable to have consistent measurement practices across the industry, this document describes the following features of such measurements:
- Essential elements, in order to provide common understanding;
- Common issues or complications;
- Sources of error ...view more

IEC TR 63227:2020 deals with the protection of PV power supply systems against detrimental effects of lightning strikes and surge voltages of atmospheric origin. In the event that a lightning and/or surge voltage protection is required to be erected, this document describes requirements and measures for maintaining the safety, functionality, and availability of the PV power supply systems.

This document describes safety requirements, constructional requirements and tests for
junction boxes up to 1 500 V DC for use on photovoltaic modules in accordance with class II
of IEC 61140:2016.
This document applies also to enclosures mounted on PV-modules containing electronic
circuits for converting, controlling, monitoring or similar operations. Additional requirements
concerning the relevant operations are applied under consideration of the environmental
conditions of the PV-module...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 ...view more

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...view more

IEC TR 63279:2020 reviews research into sequential and combined accelerated stress tests that have been devised to determine the potential for degradation modes in PV modules that occur in the field that single-factor and steady-state tests do not show. This document is intended to provide data and theory-based motivation and help visualize the next steps for improved accelerated stress tests that will derisk PV module materials and designs. Any incremental savings as a result of increased relia...view more
