Alternatively, a more accurate correction factor for
the open-circuit voltage can be calculated using the
following formula:
t
is the lowest expected ambient temperature at the
system installation site
α
voc
(%/ºC) is the voltage temperature coefficient
of the selected module (refer to corresponding
datasheet)
Electrical calculations and design must be performed
by competent engineer or consultant.

· Modules should be stored in a dry and ventilated
environment to avoid direct sunlight and
moisture. If modules are stored in an uncontrolled
environment, the storage time should be less than
3 months and extra precautions should be taken
to prevent connectors from being exposed to
moisture or sunlight, like using connector endcaps.
· Unpack module pallets carefully, following the
steps shown on the pallet. Unpack, transport and
store the modules with care.
· Modules must always be unpacked and installed by
two people. Always use both hands when handling
modules.
·
Do not
stand, step, walk and / or jump on
modules under any circumstances. Localized heavy
loads may cause severe micro-cracks at cell level,
which in turn may compromise module reliability
and void Canadian Solar Inc’s warranty.
·
Do not
support the backsheet when handling or
installing the module.
·
Do not
carry modules on your head.
·
Do not
drop or place objects (such as tools) on the
modules.
·
Do not
lift modules by their wires or junction box,
lift them by the frame.
· Stacks of modules should contain no more than 12
modules, and the frames should be aligned.
·
Do not
place excessive loads on the module or
twist the module frame.
·
Do not
use sharp instruments on the modules.
Particular care should be taken to avoid module
backsheets being damaged by sharp objects, as
scratches may directly affect product safety.
·
Do not
leave modules unsupported or unsecured.
·
Do not
change the wiring of bypass diodes.
· Keep all electrical contacts clean and dry at all
times.

· Each module has three identical barcodes (one in
the laminate under the front glass, the second on
the rear side of the module and the third on the
frame) that act as a unique identifier. Each module
has a unique serial number containing 13 (pre
March 2013) or 14 (post March 2013) digits.
