MODULE INSTALLATION
•
Install modules where they are not shaded by
obstacles like buildings or trees. Especially pay
attention to avoid partially shading the modules
by objects during the daytime. If a part of the
PV modules is always shaded, hot spot may
occur and the PV module may brea down.
•
Water stains might be caused when rain water
remains on the glass surface for a long time. To
avoid water stains, Panasonic recommends to
install panels at a slope steeper than the water
gradient.
•
Modules should be firmly fixed in place in a
manner suitable to withstand all expected
loads, including wind and snow loads.
•
The modules should be mounted basically at
the four (4) quarter points by the means shown
in Figure 1, and based on installation methods
shown in Figure 5

•
Metals used in locations that are exposed to
moisture shall not be employed alone or in
combinations that could result in deterioration
or corrosion.
•
Clearance 100mm 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.
•
Do not contact
a tip of a mounting bolt to back
sheet of the module when fixing the module to
the mounting structure rail.
•
Appropriate material should be used for
mounting hardware (the module frame,
mounting structure, and hardware) to prevent
itself from corrosion.
•
Please contact your Panasonic Authorized
Representative with questions regarding
mounting profiles for modules if needed.
