1 Scope
This document is intended to apply to terrestrial modules for consumer applications
for outdoor operation shorter than those qualified to IEC 61215. The useful service life of modules so qualified depends on their design, their environment
and the conditions under which they are operated.
This document classes those PV modules into Category 1, Category 2, and Category 3 with
respectively low, medium and high expected outdoor exposure. For the purposes of designing
this document, Category 1 (mobile applications) is for applications such as smart
phone charging which most likely have “low” outdoor exposure. Category 2 (portable
applications) is for emergency power/hiking/camping applications with “medium” outdoor
exposure and it needs to have mechanical durability testing due to repeated deployment,
potential for being dropped, and other mechanical stresses. Category 3 (attached applications)
is for “high” outdoor exposure for applications, such as for motor homes, but is not
intended for long-term utility or long-term household rooftop applications. A summary
of product categories and potential applications is presented in Annex A.
Category 1 products are intended for installation where general user access and contact
to uninsulated live parts is anticipated. Modules are not be combined in series strings
operating at more than 35 V (Voc) and do not have a system voltage rating above 35 V. These PV modules are not intended
for use in parallel with other PV modules or energy sources, unless the combination
provides protection from reverse current and overvoltage protection. The short-circuit
current is less than 8 A and the maximum power is less than 240 W when tested under
standard test conditions.
This document does not address the particularities of PV modules with integrated electronics,
such as energy storage devices, charge controllers, batteries, inverters which may
be sold in conjunction with the PV modules. This specification is intended to qualify
the PV portion of these devices. It may, however, be used as a basis for testing such
PV modules, but does not qualify the electronic portion.
This document does not apply to modules used with concentrators.
The purpose of the test sequence is to determine the electrical, thermal, and mechanical
durability characteristics of the module, and to show that the module is capable of
withstanding outdoor exposure for different outdoor durations designated as “low”,
“medium”, and “high”. Mobile and attached applications are considered to require lower
mechanical durability than portable applications, which are more prone to mechanical
damage. However, the actual outdoor exposure limits of the modules depend on their
design, their environment and the conditions under which they are operated.
