 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 HIT
® .
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.
 Panasonic 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 a risk of electrolytic
corrosion.

Recommendation of bolt torque range:
16N.m to 20N.m
 The module was tested using Unirac clamps
