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 sunlight-
resistant cable rated for outdoor use (e.g. type UF or USE) ,
for all 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
Panasonic 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
Panasonic 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 with a minimum of 1 inch clearance
between the roof surface and the modules so that
air can circulate.
•
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 corrosive-resistant
metal clamps.
•
The clamps should be made of aluminum
alloy or other material that will reasonably
protect against the a risk of electrolytic
corrosion.
•
Recommendation of bolt torque range: 16N.m to
20N.m
•
The module was tested using Unirac clamps
with the specifications below; if a different
clamp is used it must have a design load
capacity equivalent to or greater than the load
specified in this Manual.

Operating Conditions
SANYO requires that modules are 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/m
2
(60PSF)
4) Some environmental conditions could apply. Please refer to
Sanyo’s warranty exclusions.
SPECIFICATIONS
Notes on Specifications
1) Rated electrical characteristics are within –5% to +10% of the
values measured at Standard Test Conditions (STC). STC
conditions are; Irradiance of 1000W/m, 25
o
C cell temperature,
and solar spectral irradiance per IEC 60904-3. Note: At the
