ExcludedOperatingEnvironments:
Certain operating environments are not recommended for specific
Maxeon modules and are excluded from the Maxeon Limited
Warrantyforthesemodules.
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
locationswithhazardousmaterials;ormovingvehiculesofanytype.

5.2MountingConfigurations
Mounting system must provide a flat plane for the modules to be
mountedonandmustnotcauseanytwistorstresstobeplacedon
theModule,evenincaseofthermalexpension.
Modulesmaybe mountedatany angle fromhorizontal to vertical.
Select the appropriate orientation to maximize sunlight exposure.
Maxeon recommends for a good performance of the system

Commercial modules (96 & 128 cells) frames have permanently
attachedstackingpinslocateda20mmzoneonthelongsideframeat
388‐408mm(“D”areainFigure2).Mountingsystemhardwareused
with commercial modules must account for the presence of these
stackingpins(seeTable2).
Specific information on module dimensions and the location of
mountingandgroundingholesisprovidedinFigures2andTable2.

Clearance between the module frames and structure or ground is
requiredtopreventwiringdamageandallowsairtocirculatebehind
the module. The recommended assembling clearance between
modules installed on any mounting system is a minimum of 5 mm
distance.

The module is only certified for use when its factory frame is fully
intact.Donotremoveoralterthemoduleframe.Creatingadditional
mounting holes or removing the stacking pins may damage the
module and reduce the strength of the frame, therefore are not
allowed. Using mounting Clampsor clips with additional grounding
bolts or grounding metal sheets could be in compliance with this
Safety and Installation Instructions manual subject to conditions of
Section4.1
Modulesmaybemountedusingthefollowingmethodsonly:
1) Frame Holes: Secure the module to the structure using the
factorymountingholes.FourM6orM8stainlesssteelbolts,
with nuts, washers, and lock washers are recommended per
module.Bolts to be fasten according to racking supplier
recommendations.RefertoTable2forthemoduledimensions
andmountingholelocations.(Pleaserefertothearrowsonthe
Table2,E1&E2&E3&E4).
2) PressureClampsorClips:Mountthemodulewiththeopposite
clips on the longer and/or shorter side of the frame of the
module.TheclipsallowedlocationshouldbeaccordingtoTable
1.1. Installers should ensure the clamps are of sufficient
strength to allow for the maximum design pressure of the
module.ClipsandclampsarenotprovidedbyMaxeon.Clamps

these practices void the module warranty and risk glass

clamping within 50mm of
module corners to reduce
risk of frame corner

3) End Mount: End mounting is the capture mounting of the
length of the module’s shorter frames with clamps on each
shortersidesoftheframe.Threedifferentconfigurationsare
possible:1)withtwomountingrailsunderthecompletelength
ofeachshortersideoftheModules,(SeeTable1.2),2)withtwo
mounting rails parallel to the long side of the Modules (See
Table1.2)and3)withoutanymountingrail(SeeTable1.2).The
end‐mountingrailsandclipsorclamps(identifiedasA
(1&2&3&4)
in Table 1.1) must be of sufficient strength to allow for
maximum designed test pressure of the module. Verify this
capacity with the mounting system of vendor before
installation.
4) Hybrid Mount: Combination with clamps or clips located on
longerorshortersidesofModulesarealsopossible,seeTable
1.2 for allowed configurations. In any case, four clampings
pointsareneeded.
