Figure 2
A photovoltaic module may produce more current and/or voltage than
reported at STC. Sunny, cool weather and reflection from snow or water
can increase current and power output. Therefore, the values of Isc and
Voc marked on the module should be multiplied by a factor of 1.25 when
determining component voltage ratings, conductor ampacities, fuse sizes,
and size of controls connected to PV output. An additional 1.25 multiplier
may be required by certain codes for sizing fuses and conductors.
4.0 Electrical Connections
Modules may be connected in series and/or parallel to achieve the
desired electrical output as long as certain conditions are met. Please use
only the same type of modules in a combined source circuit.
4.1 General Wiring
SunPower recommends that all wiring be double insulated with a
minimum rating of 90º C (194°F). All wiring should use flexible copper
(Cu) conductors. The minimum size should be determined by the
applicable codes. We recommend a size not less than 4mm
2
. The
insulation type should be appropriate for the type of installation method
used and must meet SKII (Safety Class II) and IEC 61730 requirements.
4.2 Equipment Grounding
Please refer to the applicable regional and local codes on grounding PV
arrays and mounting frames for specific requirements (e.g. lightning
protection).
4.2 System Grounding
4.3 Series Connection
The modules may be wired in series to produce the desired voltage
output. Do not exceed the maximum system voltage indicated in Figure 2.
4.4 Parallel Connection
The modules may be combined in parallel to produce the desired current
output. Every series string or module must be fused prior to combining
with other strings. Figure 2 lists the maximum fuse size allowed. Bypass
Danger! Module interconnects pass direct current (DC)
and are sources of voltage when the module is under load
and when it is exposed to light. Direct current can arc
across gaps and may cause injury or death if improper
connection or disconnection is made, or if contact is
made with module leads that are frayed or torn. Do not
connect or disconnect modules when current from the
modules or an external source is present.
Important! Read this instruction sheet in its entirety
before installing, wiring, or using this product in
any way. Failure to comply with these instructions
will invalidate the SunPower Limited Warranty for
PV Module.
Important! For optimal performance, SunPower modules
must only be used in configurations with galvanic insulated
inverters where the positive (+) polarity of the PV array is
connected to ground protected by a fuse. Failure to
comply with this requirement will reduce the
performance of the system and invalidate SunPower’s
Limited Power Warranty for PV Modules.

visit our website at www.sunpowercorp.com/inverters to
download a technical note on this subject. For additional
assistance, contact SunPower technical support at

diodes are factory installed in the modules. Please refer to the applicable
regional and local codes for additional fusing requirements and limitations
on the maximum number of modules in parallel.
5.0 Module Mounting
The SunPower Limited Warranty for PV Modules is contingent upon
modules being mounted in accordance with the requirements described in
this section.
5.1 Site Considerations
SunPower modules should be mounted in locations that meet the
following requirements:
Operating Temperature: All SunPower modules must be mounted in
environments that ensure SunPower modules will operate within the
following maximum and minimum operating temperatures:
Maximum Operating Temperature +90 Celsius, +194 Fahrenheit
Minimum Operating Temperature -40 Celsius, -40 Fahrenheit
Care should be taken to provide adequate ventilation behind the modules,
especially in hot environments.
Design Strength: SunPower modules are designed to meet a maximum
positive (or upward, e.g. wind) and negative (or downward, e.g. static
load) of 2400 Pa (Pascals; 240 kg/m
2
) when mounted in one of the
mounting configurations specified in Section 5.2. A design strength of
2400 Pa corresponds approximately to a wind speed of 200 km/h (125
mph).
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 specific SunPower modules and are excluded
from the SunPower Limited Warranty for these modules.
No SunPower module should be mounted at a site where it may be
subject to direct contact with salt water.
SunPower modules with anti-reflective coating on the glass should not be
mounted in basic environments (those which have a PH balance equal to
or greater than 7). Basic environments degrade the coating, reduce
module energy gain, and may cause a non-uniform appearance. This is
not a concern in most areas because most outdoor environments are
acidic and therefore do not pose a problem, but SunPower recommends
that the site be checked before mounting the modules, especially in
coastal settings.
The SunPower modules with anti-reflective coating include models SPR-
315E-WHT and SPR-230-WHT.
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 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 or 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.
Modules may be mounted using the following methods only:
1) Frame Holes: Secure the module to the structure using the factory
mounting holes. Four M6 (¼”) stainless steel bolts, with nuts,
washers, and lock washers are recommended per module. Refer to
Figure 2 for the module dimensions and mounting hole locations.
2) Pressure Clamps or Clips: Mount the module with the clips on the
side frame of the module. The side frames are attached to the
longer sides of the module. The centerline of the clips should be
160mm–380mm from the end of the module. 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.
3) End Mount: End mounting is the capture mounting of the 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.
6.0 Maintenance
Inspect all modules annually for safe electrical connections, sound
mechanical connection and freedom from corrosion. Periodically clean the
module surface with water and a soft cloth or sponge. Fingerprints may be
removed with standard glass cleaner. 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 will invalidate the product warranty.
