General Installation Manual
© July 1, 2008. SANYO Energy (USA) Corp. All Rights Reserved.
USE cable, rated sunlight resistant, for
modules and interconnect wiring that is
exposed to weather.
Observe the requirements described in
sections labeled INSTALLTION and
SPECIFICATIONS.
INSTALLATION
Please read this guide completely before
installation or use of the PV modules. This
section contains electrical and mechanical
specifications needed before use.
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 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. Especially pay attention to avoid
partially shading modules by objects
during the daytime.
Contact an Authorized Representative
with questions regarding mounting
profiles for modules if needed.
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 4 inches of clearance between
the roof and the module frame.
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‖ (38mm) width
Thickness: not less than 0.12‖ (3mm)
Material: aluminum alloy
Recommendation of bolt torque range:
16N.m to 20N.m.
Operating Conditions
SANYO requires that modules be operated
within the following conditions:
Modules are intended for use in
terrestrial applications only—no outer
space use.
Modules must not be installed nor
operated in areas where, salt, hail,
snow,
sand,
dust,
chemically active vapors, acid rain,
soot, etc., are excessive.
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 and low of
the installation site.
The
installation site should be less than
2,880N/m

SPECIFICATIONS
Rated electrical characteristics are
within –5% to +10% of the values
measured at Standard Test Conditions
(STC). STC conditions are; Irradiance
of 1000W/m
spectral irradiance per IEC 60904-3.
Under
photovoltaic module may experience
conditions that produce more current
and/or
Standard Test Conditions. Accordingly,
the values of Isc and Voc marked on
UL listed modules should be multiplied
by a factor of 1.25 when determining
voltage ratings, conductor capacities,
fuse sizes, and size of controls

connected to the module output. Refer
to Section 690 of the National
Electrical Code for an additional

Mechanical Loading
Modules should be mounted at four (4)
symmetrical quarter points by the
means shown in Figures 1 and 2.
This method offers a maximum load of
2,880N/m2 (60PSF) in a static state on
the module surface. Note: This 60PSF

mechanical loading value was tested
with the following mounting devices:
