Product identification
Each module has two labels providing the following
information.
1.
Nameplate: describes the product type; rated
power, rated current, rated voltage, open circuit voltage,
short circuit current, all as measured under standard test
conditions; weight, dimensions, the maximum system
voltage, etc.;
2.
Barcode: each single module has a unique serial
number. The serial number contains the model number,
manufacturing time, and corresponding serial number of
the module (except for customer designation). Each
module has only one barcode, which is permanently fixed
to the internal part of the module (excluding black
modules) and visible from the top in the front part of the
module. The barcode is placed on the module before the
process of lamination.
Location selection
■ Select a suitable location for the module installation,
where they receive maximum sunlight throughout the
year.
■ In the northern hemisphere, the module is
recommended to face south, while in the southern
hemisphere, the module is recommended to face north.
■ The module should not be shaded at any time of the day.
■ The recommended ambient temperature should be
within -20℃ to 40℃, the temperature limits are defined
as the monthly average high and low of the installation
site, the limit operating temperature should be -40℃ to
85℃.
■ Modules have passed the IEC61701 requirements
concerning salt-mist, however galvanic corrosion can
occur between the aluminium frame of the modules and
mounting or grounding hardware if such hardware is
comprised of other metals. When the module is installed
near the sea, the module should be installed at a distance
of at least 500 m from the coastline. The offshore
installation needs to be confirmed with the manufacturer
and installed after approval.
■ Modules must not be installed or operated in areas
where salt, hail, snow, sand, dust, air pollution,
chemically active, acid rain, soot, etc., are excessive.
Modules must be sited in locations where aggressive
substances such as salt or salt-water, or any other type of
corrosive agent, cannot affect the safety and/or
performance of the modules.
■ Modules are not allowed to be placed where flammable
gases are easily generated or concentrated.

Tilt angle selection
The tilt angle of the PV module is measured between the
surface of the PV module and a horizontal ground surface.
The PV module generates maximum output power when it
faces the sun directly.
Dust accumulation on the module surface may degrade its
performance. It is recommended to instal modules with
the inclination angle according to the following table so the
accumulated dust can easily be washed by the rain.

Conventional requirements
■ The module mounting structure must be made of
durable, corrosion-resistant and UV-resistant material.
Always use tested and certified mounting structures
approved for a given system design. It is recommended to
use structures or parts manufactured by Corab S.A.
■ Ensure that the module installation method and bracket
system are strong enough to allow the module to
withstand the predetermined load conditions. Always
comply with safety instructions and precautions supplied
with the module support frames.
■ In regions with heavy snowfall in winter, select the height
of the mounting system so that the lowest edge of the
module is not covered by snow for any length of time. In
addition, ensure that the lowest portion of the module is
placed high enough so that it is not shaded by plants, trees
or damaged by ground soil moved by or through the air.
■ For ground mounting systems, the minimum distance
recommend from the ground to the bottom of the module
is at least 60 cm.
■ Provide adequate ventilation under the modules in
conformity to your local regulations.
■ Modules must be securely attached to the mounting
structure. For clamping system installation methods, the
recommended maximum compression for each clamp is
2900 PSI (20 MPa) in order to avoid potential damages to
module frames. Follow the instruction of the clamping
system supplier. Use of clamps manufactured by Corab
S.A. is recommended.
