General Information
The installation of solar modules requires a
great degree of skill and should only be
performed by qualified licensed
professionals, including, without limitation,
licensed contractors and electricians.
WARNING
• All instructions should be read and
understood before attempting to
install, wire, operate, and maintain a
photovoltaic module. Contact with
electrically active parts of the
module such as terminals can result
in burns, sparks, and lethal shock
whether the module is connected or
disconnected.
• The installer assumes the risk of all
injury that might occur during
installation, including, without
limitation, the risk of electric shock.
• PV modules generate DC(direct
current) electrical energy when
exposed to sunlight or other light
sources. Even a single module
produces enough voltage and
current, to cause shocks and burns
if safety precautions are not
followed.
• The shock hazard increases as
modules are connected in parallel,
producing higher current, and as
modules are connected in series,
producing higher voltages.
• To avoid the hazard of electric
sparks, shock, fire, burns, damage
and injury:
• Cover the entire front surface of
the PV modules with a dense,
opaque material such as a
cardboard box, during installation
and handling of the modules.
• Work only in dry conditions, with
dry modules and dry tools.
• Do not stand or step on a modules.
• Do not puncture, cut, scratch
ordamage the back sheet of a
module. Back sheet damage will
void a module’s Limited Warranty
and may cause fire. Never use
modules with a damaged back
sheet.
• Do not allow children and
unauthorized persons near the
installation or storage site of
modules.
• Completely ground all modules.
• Do not disassemble a module,
attempt any repair, open the
junction box cover, nor remove
any parts installed by Sanyo.
There are no user serviceable
parts within the module or
junction box.
• Unauthorized persons - except the
qualified licensed professional should not perform any electrical
work, including wiring.
• Wear suitable clothing, guards,
eye protection and gloves to
prevent you from direct contact
with 30 VDC or greater.
• Wear non-slip gloves and carry
modules by the frame using both
hands. Do not attempt to carry a
module by yourself.
• Do not carry a module by its wires
or junction box.
• Do not drop anything on the
surface of a module.
• Ensure all system components
are compatible, and they do not
subject the module to mechanical
or electrical hazards.
• Sparks may occur; do not install
modules where flammable gases
or vapors are present.
• Never rest or leave a module
unsupported or unsecured.
• Do not drop modules.
• Do not use or install broken
modules.
• Do not artificially concentrate
sunlight on a module.
• Do not touch the junction box
terminals.
• Do not change the wiring of
bypass diodes.
CAUTIONS
• Use a module for its intended
purpose only.
• Do not treat the back sheet, frame,
or front surface with paint or
adhesives, to avoid reducing its’
functionality, damage, and causing
inoperable conditions, and other
unknown troubles.
GENERAL SAFETY
Follow all permissions, installation and
inspection requirements.
• Before installing modules, contact the
appropriate authorities having
jurisdiction to determine permissions,
installation and inspection
requirements, which should be
followed.
• Electrically ground modules for all
systems of any voltage. If not
otherwise specified, it is recommended
that requirements of the latest National
Electrical Code (USA) or Canadian
Electric Code (Canada) or other
national or international electrical
standards be followed. Refer to “Earth
Ground Wiring” section for more
information.
• Be sure that the building or structure
(roof, façade, etc.) where the modules
are being installed has enough
strength to support the load of the
modules.
• For modules mounted on roofs, special
structures may be required to help
provide proper installation support.
• Both, roof construction and module
installation design have an effect on
the fire resistance of a building.
Improper installation may contribute to
fire hazards. Additional devices such
as ground fault, fuses, and disconnects
may be required.

• Do not use modules of different
specifications in the same system.
• Follow all safety precautions of other
system components which are used.
UL Listing Information
To satisfy UL requirements, when installing
the modules, be sure to:
1) Use only stranded or solid copper
single–conductor type PV wire or USE2 cable, 12AWG or larger conductors,
rated 600V, 90℃, sunlight resistant, for
modules and interconnect wiring that is
exposed to weather.
2) Observe the requirements described in
sections labeled INSTALLATION and
SPECIFICATIONS.
INSTALLATION
General
Please read this guide completely before
installing or using your Sanyo PV modules.
This section contains important electrical
and mechanical specifications.
• Modules should be firmly fixed in place
in a manner suitable to withstand all
expected loads, including wind and
snow loads.
• Metals used in locations that are
exposed to moisture shall not be
employed alone or in combinations that
could result in deterioration or
corrosion.
• Install modules where they are not
shaded by obstacles like buildings and
trees. Pay special attention to avoid
partially shading the modules by
objects during the daytime.
• If needed, contact an Authorized
Representative with questions
regarding mounting profiles for Sanyo
PV modules.
Notes on Installation
• Clearance between the roof surface
and module frame is required to allow
cooling air to circulate around the back
of the module. This also allows any
condensation or moisture to dissipate.
Install modules so that air can circulate
between the roof and the module.
• Leave 1 inch of clearance between the
roof and the module frame. If other
mounting means are employed this
may effect the temperature of the panel.
• SANYO recommends the installation
method and mounting profile shown in
Figure 1.
• A module should be attached on a
mount or support structure rail by metal
clamps. The metal clamp must fulfill
the following specifications.
Size: not less than 1.5” (38 mm)
width
Thickness: not less than 0.12”(3 mm)
Material: aluminum alloy
bolt torque range: 16N.m to 20N.m.
Operating Conditions
SANYO requires that modules be operated
within the following Operating Conditions:
1) Terrestrial applications only—no outer
space or Special Conditions (see
below).
2) The ambient temperature must be
within –20°C (-4°F) to 46°C (115°F).
The temperature limits are defined as
the Monthly Average High or Low of
the installation site.
3) The wind pressure load of the
installation site should be less than
2,880N/m2 (60PSF).
4) Some environmental conditions could
apply. Please refer to Sanyo’s warranty
exclusions.

measured at Standard Test Conditions
(STC). STC conditions are; Irradiance
of 1000W/m, 25oC cell temperature,
and solar spectral irradiance per IEC
60904-3. Note: At the time of
shipment, Sanyo guarantees the output
level of its modules to be -0/+10%
against Rated Power in
SPECIFICATIONS based on Sanyo’s
factory inspection at STC conditions.
2) Under real conditions, a photovoltaic
module may experience conditions
that produce more current and/or
voltage than reported at Standard
Test Conditions. Therefore, Isc value
of modules should be multiplied by a
factor of 1.25 to determine ampacity.
An additional factor of 1.25 may be
required for sizing conductors, fuses,
disconnects, etc. Please refer to
section 690.8 of the National
Electrical Code (NEC) for guidelines.
The Voc must be factored according
to the lowest recorded ambient
temperature recorded for the
location where the modules will be
installed. Please refer to section
690.7 of the NEC for more
information regarding voltage
