Mounting Configurations - SunPower SPR-XXXE-WHT series Sicherheits- Und Installationsanleitungen

No SunPower module should be mounted at a site where it
may be subject to direct contact with salt water.

5.2 Mounting Configurations

Modules may be mounted at any angle from horizontal to
vertical. Select the appropriate orientation to maximize sunlight
exposure. Specific information on module dimensions and the
location of mounting and grounding holes is provided below
(Figures 2, 3 and 4).
In order to prevent water from entering the junction box, which
could present a safety hazard, modules should not be mounted
such that the front/top glass faces downward (e.g., on a
tracking structure that positions the module with the junction
box facing skyward during sleep mode).
Clearance between the module frames and structure
ground is required to prevent wiring damage and allows air to
circulate behind the module.
When installed on a roof, the module shall be mounted over a
fire-resistant roof covering rated for the application.
The module is only IEC Listed for use when its factory frame is
fully intact. Do not remove or alter the module frame. Creating
additional mounting holes may damage the module and reduce
the strength of the frame.
Using mounting Clamps or clips with additional grounding bolts
or grounding metal sheets is in compliance with this Safety and
Installation Instructions manual.
Modules may be mounted using the following methods only:
Frame Holes: Secure the module to the structure using
1)
the factory mounting holes. Four M6 (¼") stainless steel
bolts, with nuts, washers, and lock washers are
recommended per module. Refer to Figure 2, 3 and 4 for
the module dimensions and mounting hole locations.
Only the mounting holes that are 322mm from the short
end of the module can be used for the module to meet a
5400 Pa (Pascals; 550 kg/m
strength.
Pressure Clamps or Clips: Mount the module with the
2)
clips on the longer side of the frame of the module. The
centerline of the clips should be between 160mm–400mm
from the short end of the module for 2400 Pa (Pascals;
2
245 kg/m ) design strength and between 250mm–400mm
from the short end of the module for 5400 Pa (Pascals;
2
550 kg/m e.g. snow load) design strength. Installers
should ensure the clamps are of sufficient strength to
allow for the maximum design pressure of the module.
Clips and clamps are not provided by SunPower.
End Mount: End mounting is the capture mounting of the
3)
length of the module's end frame to a supporting rail. The
end frames are on the shorter sides of the module. The
end-mounting rail and clips or clamps must be of
sufficient strength to allow for maximum design pressure
of the module. Verify this capacity with the mounting
system vendor before installation.

continuous clamp may be used to clamp the bottom
flange of the frame at the center of the long sides.
Minimum clamping length shall be 150 mm on top of
flange and 100 mm on bottom. The clamps must be of
sufficient strength to allow for the maximum design
pressure of the module. Verify this capacity with the
mounting system vendor before installation.

5.3 Handling of Modules during Installation
Do not place modules face forward in direct contact with
abrasive surfaces like roofs, driveways, wooden pallets,
railings, stucco walls, etc....
The module front surface glass is sensitive to oils and abrasive
surfaces, which may lead to scratches and irregular soiling.
Modules that feature antireflective coated glass are prone to
visible finger print marks if touched on the front glass surface.
SunPower recommends handing modules with anti-reflective
glass with 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. Product datasheets
specify the glass type used by a particular module.
6.0 Maintenance
SunPower recommends visual inspection on a regular basis of
all modules for safe electrical connections, sound mechanical
connection, and freedom from corrosion. This visual inspection
should be performed by trained personnel.
Periodic cleaning of modules is recommended, but is not
required. Periodic cleaning has resulted in improved
performance levels, especially in regions with low levels of
annual precipitation (less the 18.25 inches (46.3cm)). Consult
your dealer or supplier about recommended cleaning
schedules for your area.
To clean a module, wash with potable, non-heated, water.
Normal water pressure is more than adequate, but pressurized
water up to 100 bar (min.50 cm distance) may be used.
SunPower recommends to use a large hosepipe and not at
high outside temperature. Fingerprints, stains, or
accumulations of dirt on the front surface may be removed as
follows: first rinse off area and let soak for a short period of time
(5 mins). Re-wet and use a soft sponge or seamless cloth to
wipe glass surface in a circular motion. Fingerprints typically
can be removed with a soft cloth or sponge and water after
wetting. Do not use harsh cleaning materials such as scouring
powder, steel wool, scrapers, blades, or other sharp
instruments to clean the glass surface of the module. Use of
such materials or cleaning without consultation will invalidate
the product warranty.
