A nameplate is also affixed to the rear of each module. This
nameplate specifies the model type, as well as the main
electrical and safety characteristics of the module. It also
includes the barcode with the module
’s unique serial number
as mentioned above.
5 MODULE INSTALLATION
PRECAUTIONARY
MEASURES
AND
GENERAL SAFETY
Prior to installing modules, please obtain
information about any requirements and necessary
approvals for the site, installation, and inspection from the
relevant authorities.
Check applicable building codes to ensure that the
construction or structure (roof, facade, support, etc.) can
bear the module system load.
Canadian solar modules have been qualified for
Application Class A (equivalent to Safety Class II
requirements). Modules rated under this class should be
used in systems operating at voltage above 50V or power
above 240W, where general contact access is anticipated.
Canadian Solar double glass modules have been certified
as Type 29 according to UL 61730 and as Class C
according to IEC 61730-2 for fire performance. Single glass
monofacial modules have been certified as Type 1 or Type
2 according to UL 61730 and Class C according to IEC
61730-2. Please refer to the datasheet or the product
nameplate for the detailed types.
Consult
your
local
authority
for
guidelines
and
requirements for building or structural fire safety.
UL 61730 SYSTEM FIRE RATING REQUIREMENTS
The fire rating of this module is only valid when the product
is installed as specified in the mechanical mounting
instructions.
When installing the modules, ensure the assembly is
mounted over a fire-resistant roof covering rated for the
application.
Photovoltaic systems composed of UL 61730 certified
modules mounted on a UL 2703 certified mounting system
should be evaluated in combination with roof coverings in
accordance with UL 61730 standard, with respect to
meeting the same fire classification as the roof assembly.
Mounting systems with a System Fire Class Rating, tested
in conjunction with
‘type 1’, ‘type 2’ or ‘type 29’ fire-rated
modules, are considered acceptable for using with
Canadian Solar modules, providing the mounting system
does not violate any other requirements of this manual.
Any mounting system limitations on inclination or
accessories required to maintain a specific System Fire
Class Rating should be clearly specified in the installation
instructions and UL 2703 certification of the mounting
system supplier.
ENVIRONMENTAL CONDITIONS
PV modules are intended for use in general open-air
climates, as defined in IEC 60721-2-1: Classification of
environmental
conditions
Part
2-1:
Environmental
conditions appearing in nature-Temperature and humidity.
It is recommended that PV modules be installed in an
environment with ambient temperature ranging from -40 °C
to +40 °C. The 98th-percentile of the module operational
temperature should be of 70 °C or lower under any
mounting conditions.
If the application where the 98th-
percentile of the module operational temperature of 80 °C
is needed, please request IEC 63126 Level 1 module types.
This environmental temperature range encompasses many
locations and installation methods. Annex A provides the
reader with modeled PV module temperature examples, at
the 98th-percentile depending on the different worldwide
locations.
Please consult the Canadian Solar technical support
department for more information on the use of modules in
special climates, such as an altitude greater than 2000 m,
heavy snow, severe hail storm, hurricane, etc.
Do not
install modules near open flames or flammable
materials.
Do not
immerse modules in water or constantly expose
modules to water (either fresh or salt, e.g. from fountains,
sea spray).
Exposing modules to salt (i.e. marine environments) or
sulfur (i.e. sulfur sources, volcanoes) incurs the risk of
module corrosion.
