This International Standard lays down requirements for the design qualification and type
approval of terrestrial, thin-film photovoltaic modules suitable for long-term operation in
general open-air climates as defined in IEC 60721-2-1. This standard is intended to apply to
all terrestrial flat plate module materials not covered by IEC 61215.
The test sequence is derived from IEC 61215 for the design qualification and type approval of
terrestrial crystalline silicon PV modules. However, it no longer relies on meeting a plus/minus
criterion before and after each test, but rather on meeting a specified percentage of the rated
minimum power after all of the tests have been completed and the modules have been light-
soaked. This eliminates the technology-specific preconditioning necessary to accurately
measure the changes caused by the test.
This standard does not apply to modules used with concentrators.
The object of this test sequence is to determine the electrical and thermal characteristics of
the module and to show, as far as possible within reasonable constraints of cost and time,
that the module is capable of withstanding prolonged exposure in climates described in the
scope. The actual life expectancy of modules so qualified will depend on their design, their
environment and the conditions under which they are operated.
