Description of BS EN IEC 61215-2:2021 2021
IEC 61215-2:2021 is
available as
IEC
61215-2:2021 RLV which contains the International
Standard and its Redline version, showing all changes of the
technical content compared to the previous edition.
IEC 61215-2:2021 lays down requirements for the design
qualification of terrestrial photovoltaic modules suitable for
long-term operation in open-air climates. This document is intended
to apply to all terrestrial flat plate module materials such as
crystalline silicon module types as well as thin-film modules. The
objective of this test sequence is to determine the electrical
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 outdoors. This second
edition of IEC 61215-2 cancels and replaces the first edition of
IEC 61215-2 issued in 2016. This edition includes the following
significant technical changes with respect to the previous
edition:
a. Addition of cyclic (dynamic) mechanical
load testing (MQT 20).
b. Addition of a test for
detection of potential-induced degradation (MQT 21).
c.
Addition of test methods required for bifacial PV modules.
d. Addition of test methods required for flexible modules.
This includes the addition of the bending test (MQT 22).
e. Revision of simulator requirements to ensure uncertainty
is both well-defined and minimized.
f. Correction to
the hot spot endurance test, where the procedure for monolithically
integrated (MLI) thin film technologies (MQT 09.2) previously
included two sections describing a procedure only appropriate for
silicon modules.
g. Selection of three diodes, rather
than all, for testing in the bypass diode thermal test (MQT
18).
h. Removal of the nominal module operating test
(NMOT), and associated test of performance at NMOT, from the IEC
61215 series.
