Table 1: Low temperature correction factors for open-circuit voltage
Lowest Expected Ambient Temperature (°C/°F)
24 to 20 / 76 to 68
19 to 15 / 67 to 59
14 to 10 / 58 to 50
9 to 5 / 49 to 41
4 to 0 / 40 to 32
-1 to -5 / 31 to 23
-6 to -10 / 22 to 14
-11 to -15 / 13 to 5
-16 to -20 / 4 to -4
-21 to -25 / -5 to -13
-26 to -30 / -14 to -22
-31 to -35 / -23 to -31
-36 to -40 / -32 to -40
Alternatively, a more accurate correction factor for the
open-circuit voltage can be calculated using the following
formula:
�� = �� − ��
Voc
T is the lowest expected ambient temperature at the
system installation site.
α is the voltage temperature coefficient of the selected
Voc
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.

 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.
