be mounted over a watertight and fire‐resistant underlayment rated
for such application.
For Peformance 3 and 6 AC modules, in order to provide better
access of connection for AC cables into the microinverter, Maxeon
recommends the following installation sequence:
• When the microinverter is in lower position, then it is
recommended to install the modules from Left to Right.
• When the microinverter is in upper position, then it is
recommended to install the modules from Right to Left.
Modules mounting systems should only be installed on building that
have been formally considered for structural integrity and
confirmed to be capable of handling the additional weighted load
of the modules and mounting systems, by a certified building
specialist or engineer
.
AC Modules are only certified for use when their factory frames
are fully intact. Do not remove or alter any module frame. Creating
additional mounting holes may damage the module and reduce
the strength of the frame.
Modules may be mounted using the following methods only:
1) Pressure Clamps or
Clips: Mount the
module with the clips
attached to the longer
sides of the module.
Refer to the allowable
ranges in Section 5.0
(Appendix). Installers
must ensure the
clamps are of
sufficient strength to allow for the maximum design pressure of
the module. Clips and clamps are not provided by Maxeon Solar
Technologies. 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 shall not apply excessive force to the frame,
warp the top flange, or contact the glass - these practices void
the module warranty and risk frame and glass breakage. Figure
1a illustrates locations for top frame clamp force. Avoid
clamping within 50mm of module corners to reduce risk of
frame corner deflection and glass breakage. When clamping to
the module frame, torque shall never exceed 15 N.m to reduce
chances of frame deformation. A calibrated torque wrench
must be used. Mounting systems should be evaluated for
compatibility before installing specially when the system is not
using Clamps or clips. Please contact Maxeon Solar
Technologies for the approval of the use of non-standard
pressure clamps or clips where torque values are higher than
otherwise stated.
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.
2)
End Mount: End mounting is clipping/clamping of solar
modules at the corner of short side to the supporting rail. The
end-mounting rail and clips or clamps must be of sufficient
strength to allow for the maximum design pressure of the
module. Verify this capacity for both 1) clamps or clips and 2)
end mounting system vendor before installation.
5.3 Handling of Modules during Installation
Never lift or move the modules using cables or the junction box
under any circumstances. Do not place modules face forward in
direct contact with abrasive surfaces such as roofs, driveways,
wooden pallets, railings, or walls etc. The front surface of a module
is sensitive to oils and abrasive surfaces, which may lead to
scratches and irregular soiling.
Be careful not to touch the micro-inverter while unloading the
Performance 3 AC modules, as the micro-inverter height exceeds
the module frame slightly.
Shipping Position: X = 31.7mm
Install Position: X = 46.7mm
AC Modules are featured with antireflective coated glass and they
are prone to visible finger print marks if touched on the front glass
surface. Maxeon Solar Technologies recommends handing AC
Modules with gloves (no leather gloves) or limiting touching of the
front surface. Any finger print marks resulting from installation will
naturally disappear over time or can be reduced by following the
washing guidelines in Section 6.0 below. Any module coverage
(colored plastic tarps or similar) during installation can lead to
permanent front glass discoloration and is not recommended. The
use of vacuum lifting pads can cause permanent marks on the front
glass.
When a residential installation (with “RES” in the description) is
designed/planned using SunPower/Maxeon modules with different
Part Numbers (SKU’s), in order to minimise cosmetic differences
between modules, please ensure the anti-reflective supplier of the
modules are identical. This can be done by referring to the product
description, and looking for AR-XX, where “XX” denotes the supplier
and these characters shall be all identical.
Shading incidence need to be avoided during PV system operation.
The system is not supposed to be energized until the mounting
scaffolding or railing have been removed from the roof. Ties or
