This International Standard series lays down IEC requirements for the design qualification and
type approval of terrestrial photovoltaic modules suitable for long-term operation in general
open-air climates, as defined in IEC 60721-2-1. This part of IEC 61215 is intended to apply to
all terrestrial flat plate module materials such as crystalline silicon module types as well as
thin-film modules.
This standard does not apply to modules used with concentrated sunlight although it may be
utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests
are performed using the current, voltage and power levels expected at the design
concentration.
The objective 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 general open-air climates.
The actual lifetime expectancy of modules so qualified will depend on their design, their
environment and the conditions under which they are operated.
