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
αVoc
(%/ºC) is the temperature coefficient of the
selected module (refer to corresponding datasheet)

UNPACKING AND STORAGE
PRECAUTIONS
· Module 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.
· Unpack module pallets carefully, following the
steps shown on the pallet. Unpack, transport and
store the modules with care.
· Modules must always be unpacked 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.
·
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.
PRODUCT IDENTIFICATION
· Each module is equipped with two identical
barcodes (one inside the laminate under the front
glass, the second on the rear side of the module)
that act as a unique identifier. Each module has
a unique serial number containing 13 (pre March
2013) or 14 (post March 2013) digits.
· A nameplate is also affixed to the rear of each mo-
dule. This nameplate specifies the model type, as
well as the main electrical and safety characteristics
of the module.
