Mounting Configurations - Maxeon SPR-P5 UPP Series Safety And Installation Instructions Manual

Operating Temperature: All Maxeon modules must only be
mounted in environments that ensure they will operate within the
following temperatures:
Operating Temperature range
(ambient)
Adequate ventilation should be provided behind or underneath the
modules, especially in hot environments.
Shading: Modules should be installed so that permanent shading of
cells is avoided and partial shading that may occur during certain
times of the day or year is minimized. Permanent shading is defined
as shade that is cast over the same position (of constant area) of
the solar module throughout the generation hours of the day.
Shading may induce in certain cases strong energy production
reduction, even in case of small shading and should be avoid as
much as possible, especially at mid-day when the production is
maximum.
Design Strength: Maxeon modules are designed to meet a positive
(downward) and/or negative (upward) withstanding test pressure
when mounted as per the guidelines in Section 5.2 and
configurations in Appendix. Test loads are for information purposes
only; design loads should be considered for the project design.
When mounting modules in snow prone or high wind environments,
special care should be taken to mount the modules in a manner that
provides sufficient design strength while meeting local code
requirements.
Excluded Operating Environments
Certain operating environments are not recommended for Maxeon
modules, and are excluded from the Maxeon Limited Warranty.
Modules are designed for a maximum altitude of 2000 m.
No Maxeon module should be mounted at a site where it may be
subject to direct contact with salt water, or other aggressive
environment.
Modules should not be installed near flammable liquids, gases, or
locations with hazardous materials; or moving vehicles of any type.
Performance Series Mounting Orientation
Commercial Performance Series (P-Series) modules are designed to
perform better if installed in landscape orientation. In landscape
orientation, P-series modules maintain higher power in conditions of
row-to-row shading and/or edge soiling.

5.2 Mounting Configurations

Modules integrated into or mounted over a roofing system must be
mounted over a fire-resistant roof covering rated for the
application. Modules may be mounted at any angle, from horizontal
to vertical. To reduce soiling, modules should be mounted at a
minimum of 5 degrees.
Specific information on module dimensions and the location of
mounting and grounding holes is provided in Appendix. The system
installer is responsible for the determination of location-specific
load requirements.
It should be noted that watertightness is not ensured by Maxeon,
therefore, if water management is required, the mounting system
should be designed accordingly.
The module is only CSA Listed for use when its factory frame is fully
intact. Do not remove or alter the module frame, and do not create
additional mounting holes because doing so may compromise the
integrity of the frame.
Modules may be mounted using the following methods only:

5.3 Ground Mount Applications for Bifacial modules
Various environmental and installation parameters affect bifacial
gain. Albedo is a measure of the amount of light reflected from the
ground surface. A higher albedo factor will increase irradiance on
the backside and result in higher bifacial gain of the module. The
surface conditions, month of the year, time of day, GHI and DNI
both influence the amount of incident rearside irradiance.
Maxeon recommends to check with solar module mounting
hardware supplier in order to determine the Structure Shading
factor of your particular installation. The Structure Shading Factor
varies with racking system design, irradiance, albedo and height of
MAXEON SOLAR TECHNOLOGIES, LTD.
Frame Holes: Secure the module to the structure using the
factory mounting holes. Four 1/4" stainless steel bolts, with
nuts, washers, and lock washers are recommended per module;
tightened to a min. torque of 10 in-lb. This method has been
certified by a third-party organization according to UL 1703.
For frame hole mounting, modules must be secured using the
holes shown in Appendix.
Clamps: Mount the module with the opposite clamps on the
longer and/or shorter sides of the module. Installers should
ensure the clamps are of sufficient strength to allow for the
maximum design pressure
of the module. Clamps are
not provided by Maxeon.
Clamps that secure to the
top of the frame must not
deform the top flange.
Clamps must apply force
collinear with the 'wall' of
the module frame and not
only to the top flange.
Clamps or installation procedures that put excessive force on
the top flange will deform the frame, void the module warranty
and risk glass breakage. Figure 1a illustrates locations for top
frame clamp force. When clamping to the module frame,
torque should never exceed 132 in-lbs (15 Nm) to reduce
chances of frame deformation and/or glass breakage. If the
clamp manufacturer recommends a specific torque value which
is lower than 132 in-lbs (15 Nm), the installer should use the
clamp manufacturer's torque value. If the clamp manufacturer
recommends a specific torque value which is higher than 132
in-lbs (15 Nm), the installer should contact the clamp
manufacturer for acceptance of the 132 in-lbs (15 Nm)
maximum torque value or to find alternative clamps. A
calibrated torque wrench must be used. Mounting systems
should be evaluated for compatibility before installing specially
when the system is not using Clamps.
Minimum clamp width allowance is ≥35mm, and for corner
clamping the minimum clamp width is: ≥50mm. Clamps should
not be in contact with the front glass and clamps should not
deform the frame.
Maxeon does not recommend nor endorse the application on
the modules of clamps which, as part of their grounding or
earthing function, have teeth or claw features (see Figure 2)
which may, individually or cumulatively, cause the module
breakage due to (and without limitation):
i. the grounding features touching
the front glass which is incorporated
into the module due to the position
of such grounding feature,
ii. the shape, the position or the
number of the grounding features
deforming the module top frame, or
iii. the clamp being over-torqued
during the installation.

glass may break
