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
A or Class C for fire performance according to IEC
61730-2 for fire class performance, 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.
UL61730 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
(Class A, B or C), tested in conjunction with fire rated
“Type 29” rated modules, are considered acceptable for
use with Canadian Solar modules, provides 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 temperature ranges from -40 °C to +
40 °C. For modules operating under such conditions,
the 98th-percentile of the module operational
temperature must be of 70 °C or lower.
This environmental temperature range encompasses
many locations and installation methods. Annex B
provides the reader with modelled PV module
temperature examples, at the 98th-percentile
depending on the different mounting method and
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 2000m, 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, i.e. 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.
Do not expose modules and their connectors to any
unauthorized chemical substances (e.g. oil, lubricant,
pesticide, etc.), as modules may incur damages.
Canadian solar modules have passed salt mist
corrosion resistance test according to IEC 61701, but
the corrosion may still occur on where the modules
