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

optimization and approval of project specific module
string lengths.

4.0 UNPACKING AND STORAGE

PRECAUTIONS
 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.
 When unloading modules pallets from containers,
please use a fork lift to remove the module pallets, and
the forklift should be close to the ground in order to
avoid the top of module pallets touching the top of the
cabinet door. The thickness of forklift teeth should be
less than 75mm, and the length of the forklift teeth
should be longer than 2300mm, when unloading the
module pallets with short side. For unloading CS7N-MS
and CS7L-MS modules, the length of the forklift teeth
should be longer than 1250mm and the width of forklift
teeth should be wider than 600mm (from outer edge to

outer edge ).
 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 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 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's warranty.
Do not support the module by 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 use sharp instruments on the modules.
