Module Mounting
This section contains information for AC Modules.
Ensure that you use the correct
information for your module type.
The Maxeon Solar Technologies Limited Warranty for PV Modules is contingent
upon modules being mounted in accordance with the requirements described in
this section.
5.1 Site Considerations
AC Module should only be mounted in locations that meet the following
requirements:
Maximum Altitude
: AC Modules can be installed in locations with a maximum
of 2000 meter altitude.
Operating Temperature:
AC Modules must be mounted in environments that
ensure that the modules will operate within the following maximum and
minimum temperatures:
Max. Operating Cell Temp.
+85°C
Max. Operating microinverter Temp.
+ 60°C
Max. AC Module Ambient Temp.
+50°C
Min. AC Module Operating Temp.
−
40°C
Design Strength:
AC Modules are designed to meet a maximum positive (or
upward, e.g. wind) and negative (or downward, e.g. static load) design pressure
when mounted in the mounting configurations specified in Table 1 and 2 for the
details on load ratings and mounting locations. AC Modules have also been
evaluated to IEC 61215 for a positive or negative design load of 3600 Pa with a
1.5 Safety Factor.
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.
Important!
The following image and tables show where to mount in module
frame and the allowable load ratings corresponding to the mounting zones
chosen. To use the tables, identify the two mounting zones in which you wish to
mount. You may choose to mount at any location in zones A, B, and C, as long as
the mounting points are symmetric about one axis of the module. Identify the
combination of mounting zones you have chosen in the table and then refer to
the corresponding load rating. Note also that load ratings are different for
modules supported by rails; versus systems that attach modules underneath the
module frame or without rail support.

Additional Authorized Operating Environments:
Modules can be mounted in the following aggressive environment according to
the test limits mentioned below:
Salt mist corrosion testing: IEC 61701 Severity 6
Ammonia Corrosion Resistance: IEC 62716 Concentration: 6,667 ppm
Excluded Operating Environments
Certain operating environments are not recommended for Maxeon Solar AC
modules, and are excluded from the Maxeon Solar Technologies Limited
Warranty for these modules. Maxeon’s modules should not be mounted a site
where it may be subject to direct contact with salt water, or other aggressive
environment. Maxeon’s modules should not be installed near flammable liquids,
gases, or locations with hazardous materials; or moving vehicles of any type.
